    So the Avant was at "Skunkworks" for 3 months getting "Simo-ized". Just got it back a little while ago. I know she's dirty but I wanted to share. So happy to have her back.

    Can't wait to begin R&D. better images soon and of course some discussion about the custom modifications. I'm still not allowed to go into too much detail....yet.... but I'll share what I can

    Looks great! That front looks awesome. If I had any confidence in someone matching my paint properly I would do the same.

    I just has my Avant detailed as well....and "Opti-coated".....amazing difference...better than new.

    Thanks! I'll start getting into the custom mods over the weekend when I have time to go through the photos.

    @coy_can... yeah man I need to get her detailed right away. Planning to do a little shoot with a TT-RS and Blizzard this weekend... If we don't end up enjoying too many cold ones

    "Opti-coated"? do tell...what's this? wax/sealant?

    ^ ceramic clear coat. This site would do a better job of describing it than I could

    http://opti-coat.com

    I had it done when I bought my car (back in Dec 08) and just had it reapplied. It really does an amazing job of keeping the paint looking great.

    Thanks bud! I just scheduled a detail with a local Opti-Coat distributor. I'll be talking with them about Opti-Coat after I see how they do on the paint correction.

    I was never into "low and slow"...but "show and go" works for me. I know my Avant is rough around the edges but I try to keep her looking purdy.

    Oh man! Warren I can't tell you how tasty that frosty mug of Dos Osos looks! We've got to enjoy a round when I get back down to SoCal for a visit.

    Been going back and forth with Kevin at Acon Kits for 8+ weeks... Over that time, I tried to order several times.. Each time, there were more questions that required photos of the hardware (field serviceable or non) (I have 2 sets of STaSIS hats, early and late style, but both 12 bolt) photos of the rotors both use the turbolator style race rings...and micrometer measurements of calipers, pistons, bores, etc were taken to make sure that we were getting the right parts. Even after all that, for something as seemingly simple as the anti-rattle clips, (even once the caliper had been identified by Alcon UK) there doesn't seem to be much certainty even though we have the part number.

    I pointed out that during all this back and forth, I'd become aware of Steve Petty Motorsports (SPM) marketing a 375mm Alcon rotor with the new style Alcon "S" curve pre-mounted on new hats with new caliper brackets...for $300+ LESS than AK was selling the 370mm rotors and mounting hardware. I also mentioned to him that AK had now changed their website stating a 2-4 week special order time on those parts. I did find an Audi Club discount for $25 off at AK on rotors but that is off the price of a pair. After everything I'd been through with AK, I decided to go ahead and order anyways... After all, I had no luck reaching anyone at SPM by phone and none of the sales people returned my voice-mails. There may be an issue with their phone system as I tried numerous times and some extensions just hung up when dialed... For some reason, when I tried to order and apply the discount at AlconKits, (it makes you login to your account to do that), it would refuse to complete the transaction by not allowing me to login and clearing the cart at the same time. Maybe it was just not meant to be. Sometimes you can't push the universe too far or it starts pushing back...

    My poor Audi technician put in much more time taking measurements and getting numerous photos than he should have needed to in order try and resolve this brake issue and I wholeheartedly thank him for his time and continued friendship.


    I was ready to bite the bullet on a custom full race setup with another manufacturer...

    Then I noticed that one of SPM's employees, Josh, was active daily on the the forums. I called his extension at SPM and left a message. He called me back right away and said he had the 375mm setup in stock and ready to ship. He asked me to place my order over the website, which I did. Josh called me back minutes after I placed the order to clarify some things and told me that the order would be shipped, Express... Can't wait!

    Might just be able to get my car out on track for AudiTron this weekend, otherwise, I'll only be riding the passenger seat instructing. We'll see what happens. Things will line up or they won't...I'm not going to cut any corners where safety is involved for myself or others on track with me.

    But at least an end of sorts is in sight.


    Just wanted to let you know how things are shaking out/shaping up...as well as let you know about my experience with SPM.

    Just thought i'd share the other side of the story here and how that 8 weeks came to be.

    As most know, obtaining some of this Alcon stuff has been a challenge as of late. Alconkits decided since we (obviously) have an affiliation with Alcon, we could try to fill the gap left for those people who could no longer get parts for their Stasis BBKs. It's been a learning process for us, trying to identify what's been used in various Stasis BBKs. We recreated the two types of hat hardware (actually required that we have a one-off "bobbin" machined- we weren't expecting that.....), identified as many disc applications as we could, pored over the Stasis instructions, asked as many installers, shops + customers, even some Stasis employees, about info. Still there's been some bumps along the way but we've always been forthright in our attempts to source what is needed for the customer. We're not trying to gouge anybody or jerk anybody around.

    Aside from the basic components of the brakes, then there's been the challenge of identifying the changes that have occurred in the Stasis kits and their part numbering system. Considering that we have not physically measured most of the Stasis pieces, aside from the hat hardware, we've had to rely on what information we could mine from the web in order to iron-out the specifics and ensure the parts we provide are correct. On top of that challenge, Alcon's ever-evolving product line doesn't make it easy to identify what's needed to fit the Stasis BBKs. But we try our best.

    However, that above information is basically irrelevant to Marcel's plight in getting parts. With respect to the anti-rattle clip issue, I admit it took a while to get that information from Alcon and still it wasn't entirely clear to us which clip is correct or what/why there's a different clip for the three different Mono6 calipers (three different part numbers in our system). You'll recall I suggested that, A. you could do without the clip for the time being because all it does is provide light spring pressure on the pad to keep it from rattling in the caliper when the brakes aren't applied. It's not critical to the operation of the brakes. Or B., you could order both clips and see how they compare. They're not terribly expensive at $20-something each. Not cheap by any means, but not kick-in-the-head expensive. I'd even have been willing to eat the cost of the unsuitable pair of clips to make sure I got you what you needed.

    After the clip saga, which I own-up to, I waited weeks to get pictures from you to confirm what were the specifics of your rotors. Sorry, but the reason for needing that important information is there is a physical difference between the various Alcon 370x32mm rotors. One is a Turbulator extreme duty 48 vane rotor with an additional 2mm of offset built into the mounting lug area, the others are a common "flat" 48 vane rotor with considerable additional weight. W/out confirmation of your existing rotor type, I could not get the ball rolling on sourcing rotors due to the dimensional difference, as well what hardware they use. I clearly explained that in our email exchanges.

    The lead time on the rotors is because we're still held to ordering 3-pair shipments. It's hard to tie up capitol on 2 pairs of these rotors if we don't have someone lined up to buy them. So as we gauge the demand for Stasis replacement disc requests, we build-in that 2-4 week lead time, expecting other orders to come in. Truthfully they've lately been arriving much more quickly than that

    With respect to the online ordering difficulties, I personally checked your account for operation on my end (remotely, mind you, not at the hosting site for the website or by doing it as a site admin) and it worked. After you still were not able to get your order into the site for some reason, I called & left a voicemail with my personal contact info so that I could place the order manually for you if you would like to do so. Didn't hear back from you.

    Had to assume you'd decided enough was enough. No offense taken on my part, as I can understand the frustration and delay you went through. Nonetheless, I wanted to be clear how it played out to prove we're not complete incompetent boobs on our end at Alconkits, who did nothing to assist with your desire to get replacement parts.

    Good luck with the SPM stuff going forward. We'll keep refining our Stasis replacement program to do our best to get customers what they need.

    Keep the shiny side of the car up & get some cooling to those brakes. Effective cooling is absolutely paramount to making your expensive pads and rotors last MUCH MUCH longer, which is in conflict with those of us who would prefer you use up brake parts as fast as possible!

    For those unaware, this is Kevin Lehmann, Engineer & Sales Associate at AlconKits.

    Hi Kevin,

    Thanks for visiting the thread and your clarification of things on your end. I never implied that you or that AlconKits were "incompetent boobs on your end at AlconKits." My apologies if that is how it was interpreted. I stated facts and perhaps did not explain clearly enough what had happened.

    It did in fact take a week or two at times to get photos and/or measurements of the parts in question. (calipers, rotors, I have both types of STaSIS hats/rotor, hardware, piston bores/pistons, and clips) I don;t deny that at all. Since my Avant was at the dealership for 3 months, it could not have tied up the lift of the shop foreman during that entire time so I often had to wait for the car to be brought back in and raised, wheels, calipers, and hats/rotors to be removed so that new photos could be taken of the requested angles or parts. The dealership was extremely accommodating and did not charge me for this repeated disassembly/reassembly. But I also could not expect them to drop re-prioritize other customer work during this period of time.

    This was an unfortunate sequence of events that your company found itself in the middle of much sooner than expected. While many of us saw the writing on the wall for STaSIS, nobody could have seen how fast they would fall apart. AlconKits stepped up to try and fill a void in the marketplace and allow those of us with the STaSIS/Alcon BBK to have a new source for replacement parts. For that I commend, applaud, and thank you. I have not given up on AlconKits as you may have assumed. I gave up on getting replacement rotors in a timely fashion and the clock was ticking with the car still at the dealership. They were incredibly gracious considering that during that time, 15-30 customer cars could have taken the space occupied by mine and brought in many times more money than I was eventually charged. In seeking to put an end to the delays, I turned to SPM (for their 375mm Alcon Rotor/hat replacement kit which comes pre-assembled and includes the new mounting bracket necessary to relocate the caliper out 2.5mm for several hundred cheaper than Alconkits cost for rotors and hardware which then require assembly time, etc.) I had difficulty reaching anyone at SPM for awhile so, as I wrote you in my last email, I turned to another manufacturer altogether. I called Stoptech and spoke at length with Ryan Kim, their race engineer and learned quite a bit more than I'd anticipated about upgrading as well as braking as it relates to the Audi B8 platform. We spent time discussing a one-off custom upgrade but that also would take more time than I had/was willing to inflict on the dealership.

    In a last ditch effort to find a solution I contacted Josh at SPM. Left him a message and he called me back moments later and confirmed that he had the necessary parts in stock. I had them sent overnight and proceeded from there. The dealership could not get it done in time for that weekends AudiTron event at Thunderhill but it is now done. Now I have to wait until Fall as I no longer run the Avant at anything but AudiClub track events. I'll use other cars for other club events although with Summer upon us, most clubs are dialing back their events due to the heat. The Avant will be back on track for AudiFest at Sonoma Raceway for it's first round of R&D on the effectiveness of the brake cooling setup that has been custom fabricated by Simo (Thank you Simo!). If I still have brake cooling issues, I'll be looking at a full race setup from StopTech...otherwise, I'll continue with the Alcons. I'll probably order another set of Alcon rotors from AlconKits (regardless of cost) so that I have a set for when I show the car on the lawn at Legends of the Autobahn in Carmel this Fall.

    Regardless, the SPM setup is an unknown entity and it remains to be seen how they'll perform. I hope for the best but always try to prepare for the worst. Since I'm still waiting on some thermal tape, I won't be even bedding the ST-47 pads for awhile. So, the Avant will be stored and only occasionally shown over the Summer.

    Anyway, I wanted to clear the air regarding AlconKits. Dealing with Kevin by email and phone was always a good experience, although frustrating at times due to the attempts to unravel the STaSIS mess. I sincerely hope that our relationship is solid and look forward to doing business with him and AlconKits in the future. If anything, I have nothing but respect for the fact that he did not want to sell me anything until he could be absolutely certain that I was getting the correct parts. Thank you Kevin!

    Marcel,

    I was at the track yesterday.. and I ran a lot faster than I expected.. but I really feel that these leather seats in our cars suck and I am seriously considering seats next year. Have you done seats at all or considered it? I would imagine it would really help with lap times as you don't have to focus on getting back into a proper seating position all the time?

    I have the S-Line Alcantara sport seats so I don't move at all laterally, I also have harnesses which I have not yet installed on the Avant due to concerncerns about the rear ,punting angle potentially breaking the seat back. I've been considering a harness bar or caging the rear of the Avant since it rarely gets driven on the street anymore. In the meantime, I use the centrifugal lock. The process is fairly simple. Find your proper seating position. Then lay the seat back as much as possible and jerk the seat belt so that it locks. Now raise you seat back to the original (proper) position while holding the belt in the locked position. You should find yourself held firmly in place by the belt which will not move during your session. It has helped me immensely when riding shotgun as an instructor in a variety of different cars that often don't have harnesses or even sport seats, much less bucket seats.

    Hope it helps.


    btw, nice sig

    I tried that seatbelt lock but i find its not consistent with the locking.. and since my seat is still a leather surface i still slide around. I think i may just sucker up and get a bucket if i am still tracking a few times ayear.. and satisfy a want since i have been cravin one for a long time.. lol

    And you shld help me find more worthy sigs.. hahahah

    Memorial Day. It is a day for remembering the men, and now, women who have fallen in service to our country. Whether you agree with the wars or conflicts is irrelevant as it was those men and women that were called and went regardless of beliefs or ideological conflicts. Their loss is a loss to their families, their friends, and us all... as a country. I have long believed that Memorial Day is also a day to give thanks for being alive wherever you are and whomever you are with. Libations to the fallen and gratitude for life and all we are able to enjoy every day that we often take for granted.

    Thanks for the tip. I took Blizzard in for a bath at a local dealer for opti-coat. The owner wasn't there so I couldn't get a quote but I'm definitely interested in getting it done.

    I want to get the clear bra pulled off. The front bumper is not wrapped and having the hood and fenders as well as quarter panels done makes it look like the bumper isn't color matched.

    Haven't decided whether to just re-wrap the front clip afterwards or do a full wrap...

    Unfortunately, on the way to the detail shop, I experienced some severe vibration as soon as I got up to speed on the freeway so I took it back to the Audi dealership.

    They were nice enough to set me up with a 2014 S4 while they figure out what is causing the vibration. Not bad for a stock car. The B8/8.5 S4 has come a long way in 4 years.

    I love the meaty grip of the wheel but find the flat bottom to be obtrusive in city driving/or maneuvering. I want that sport diff badly.

    Marcel, with all the serious tracking you do, I would personally believe that having the full clear bra on your car is a must, including on your new bumper. I also have a feeling you won't be happy looking at the "lines" on a front clip only treatment. They do say that the clear bras can yellow over time, especially the earlier ones and especially on a white vehicle. People today are saying great things about the newer Expel Clear Bra products though. I've also heard good things about the Opti coat. It offers an extra, harder than your paint's top clear coat layer with a "sacrificial" layer of protection against light surface scratches as well as protects from contaminants eating your clear coat. However, that said, you would still want to clean up things like bird droppings, etc right away. Should keep your car cleaner longer and no more need to frequent wax or seal.

    Also, thank you for sharing your comment about the flat bottom steering wheel. I think you just saved me a few bucks on a possible mod

    I have a couple of other cars that have the front clip clear bra'd and don't notice it at all. As long as the installer wraps around the edges and is conscientious about those areas, it is not noticeable. It's the template cut OTS clear bras that drive me nuts since the edges catch wax and dirt. I don't notice any coloration issues with my other cars. Granted both of those cars are silver. The ibis white of the Avant shows a slight yellowing but no big deal considering that it was on for 5 years and withstood quite a bit of punishment. I expected the bra to yellow more than it has and intended to replace it awhile ago.

    It's always important to get bird dropping and other contaminants off the surface ASAP whether it's paint, clear bra, whatever... The acids can etch the surface and obviously staining can occur. That's why I keep a waterless wash/wax and microfiber ready to go in the car at all times.

    Regarding the wheel,don't get me wrong, they are nice looking and feels great while cruising straight and works fine on a casual windy road but I find the flat portion to be really annoying when making even just a 90 degree turn (every city block). I just wish it was round...

    Got a call from the dealership tonight. Seems that the Raybestos ST-47 front pads had a bit too much meat on them and were not allowing the pistons to move properly. They sanded the pads down .5mm each and then did a road test and say that the vibration is completely gone.

    I still have to wait to bed them. We are waiting on some thermal insulation tape to shield certain components during the bed-in process.

    Before I go through the rest of the brake cooling setup photos and get them ready to post...here's a shot from underneath to give an idea of what's been done.

    Any guesses as to what's been changed?

    Sweet! Gotta love OEM subtlety.

    I doubt that most techs would even notice the mods unless they were looking for them.

    I believe you have a large hole underneath near each front wheel for more air flow to the brakes.. hard to tell if its directed air flow though from that photo.

    Are those cooling vents for your brakes? Do you have tubing or piping that directs the air flow directly to the brakes? If so, is that plastic or some other type of material?

    Glad to see your still rocking the Avant love man.

    I'll play. I see NACA ducts and a scoop on the right hub.

    What's the deal with the green washers?

    You are all on to some of what's going on here...
    @The Ghost, the green circles are not washers. They are paint. It lets anyone servicing the Avant know which bolts to remove in order to drop the belly pan.

    The NACA ducts are an OEM Audi part. Any guesses as to where they came from?



    A closer shot of one of the duct and the backing plate air scoop.


    The air scoop and splash shield are modified VW Phaeton parts but they wouldn't have done much without all the other mods since there is so little airflow in the B8 platform wheel wells.

    Early mockups of the backing plates/splash shields to determine how they would need to be modified


    Modified VAG parts


    Remember though that back in December when I upgraded my bumper to the Caractere one, there was a method to my madness...

    After all, I knew I had this project coming...although the scope was still unknown...

    Those massive honeycomb intakes were going to be functional by the time we were done...


    Photo courtesy of user "chet" who spotted Blizzard hiding in the back of Stevens Creek Audi on a nice Spring day.

    more coming soon

    So, back to that set of VW Phaeton scoops... Great for directing air where we want to the inner area of the rotor where it connects to the hats. But...to direct air, there has to be air to direct...

    So we've got those NACA ducts that bring in air from under the car as well as the air dams to create a high pressure zone in front of them forcing air into the NACA ducts.


    But I need serious brake cooling...

    Take a peek through the honeycomb mesh and what do you see?



    Do you see what I see?

    Where's that going?

    Aha!


    So now we have multiple paths for air to reach the scoops. Thank god Blizzard isn't an S4... I feel sorry for those guys with their intercooler on the side blocking airflow...

    As if $2k in parts wasn't bad enough then they'd also need to relocate their intercooler... It's almost as if Audi didn't want anyone to take anything but an RS model to the track...

    Speaking of which, at least they wouldn't need the belly pan I'm using since it's from a 2012 S4. Looks almost identical from the underside but on the engine bay side, it's completely different from the A4.
    The A4 belly pan uses hundreds of cubes of different sizes strategically located in order to attenuate engine noises that the average A4 owner might find offensive apparently...

    The S4 belly pan is smooth with an even layer of a soft slick dampening material.

    That brings me back to the corners now where the NACA ducts are as well as their channels and the "winged" wheel well grate... I call it "winged" because they are not just slats but actually have a wing profile as well as curvature to them.

    They are meant tho accelerate airflow into the wheel well while helping to channel water and debris away from the brake air scoops.

    Here's a better angle that should help illustrate where air is being channeled and how debris is blocked by the grate while air gets through. It also shows how the scoop lines up with the channel and grate.



    Any guesses as to the source of the NACA duct/grate panel? I'll give you a hint. It's a quattro.gmbh part

    The B7 Rs4's have those ducts but what you have looks larger...my guess is R8.

    Dam, that's good!

    The only way I've seen for s4s to do it property is through the lower part of the front grill and cut a hole in the wheel well like psychotnik did.

    Partly correct... the corner sections are from the TT-RS and the lower lip edge is from the R8 V10 Plus... albeit with lots of custom work on all of the pieces...

    I'll post what the parts came from. I won't have part numbers as I was never given a breakdown of parts by p/n. Lots of stuff went on and was scrapped during the 3 months that the install occurred.

    It's not for the faint of heart. The bill was close to 3k and it's still not 100% done... but if I still have any brake cooling issues, then the problem is obviously located somewhere between the brake pedal and the seat back.

    Just remember that none of this stuff is a bolt on solution and requires a significant amount of customizing to make work on the B8. If you were local, I'd recommend going to see Simo at Audi Stevens Creek for the "treatment".

    Thanks. Simo spent a lot of time measuring, planning, and revising before the real cutting and grafting began. He's meticulous and a stickler for OEM solutions believing that they are the usually the best since they've been through rigorous engineering and testing to make certain that they are effective.

    Interesting.. how'd he route the air laterally?

    Fortunately, A4's can take the direct route.

    Any chance you'd try to run actual ducting through there to force more air directly through the created cavity to the outlet in the wheel well?

    No. The path is direct on both sides.

    A B8 S4 would almost certainly be forced to do that but it's not ideal.

    This is the reason that Simo chose to stay OEM throughout. The TTRS ducts just like any Audi R8 or "RS" model are designed to prevent water and debris from reaching the rotor and caliper.

    If you run a NACA duct or front ducts directly into the wheel well, they will allow water and debris (gravel, rubber marbles, etc.) to potentially blast your brakes.

    If you remove the splash shields, then you make the situation even worse as that water and debris would be directed right at the backside of the rotor and caliper.

    If you run a set of tubing into the splash shield or like the S4 on QW, then you are really forcing any debris or water straight onto the rotor and caliper.

    If you have a race car and only track when it's dry, then that's a great solution. High level race cars often have valves that can be manually and/or thermostatically operated to only cool as needed as well as divert debris and water.

    Similar to what you would find on this Audi R8 LMS I spotted sitting on a chassis dyno before the Monterey Grand Prix. (and yes, I got permission to take this photo)

    What you are trying to achieve is not that hard to do. Psychotik is on the right path. If you guys want absolute air, and at all speeds, just run these on a toggle switch. They are cheap:

    swoardrider,
    Some really innovative ideas on your links. Seems like with 3-d printing, one could make a rooduct for our cars. The fans are a really cool idea, although it looks like they are in the duct which would still require some routing in our cars.
    And Quattro, what a fantastic effort to help educate our community on brake cooling. Unfortunately not all of us have the patience and funds to make such a refined end product! Learning a lot in this thread.

    Hi, I'm the guy with the Rooducts.
    Thanks for looking.
    I was at an Audi meet at Pocono earlier this year and had a look at what you're up against.
    If anyone serious is near Buffalo for a day, let me know.
    Buffalo is conveniently located near Toronto, Watkins Glen, Beaver, Nelson's and not too far from Mid-Ohio, Pocono and many more.
    Some measurements can work but having the car to try parts on is the best way to be sure they fit and don't run into things they shouldn't.
