Big Brake Kits - who's running what?

[onequick4door]

I'm going to purchase a BBK right after the new year. Didn't see any compelling Black Friday or other discounts that make me want to pull the trigger earlier than that. It would also be a good thread for future reference.

A Couple Questions to make this valuable to the forum:

1. What Kit - Brand, Rotor Size, # of brake pistions, part #, weight of parts if you've weighed them
2. What Wheels are you running - Diameter and more importantly the offset to know what wheels have cleared which calipers

I will edit the thread as information is presented.

Rotor Size - 340mm
Piston - 1

Weight -

Rotor: 23.4 lbs
Caliper (with pads): 18.8 lbs

TTRS Conversion

Rotor Size - 370mm (what I found online through parts search)

I personally am not interested in the TTRS conversion due to weight, but if people know all the stats off hand I'll continue to update the thread.

I have done quite a bit of these on the New MK7 VW. They are a nice kit as well for sure.

Resurrecting this thread as I'm looking to do a brake upgrade before some spring time track events I have lined up. I'm curious of anyone's feedback that has already done a BBK upgrade. I'm slightly leaning towards the VWR kit. Their rotor is slightly larger than most other kits (also slightly heavier) and the caliper weight is nice for a 6 piston. I also like the extra stopping power of a 6 vs 4 piston though I'm not opposed to a 4 piston if someone has rave reviews about a particular kit. I'm also curious is there anyone that does pattern matching on 2 piece rotors for the rear? I haven't seen any but figured I'd at least ask.

I ended up ordering the Stoptech Trophy six piston kit with the 355mm rotors to fit under my 18' forgestar F14's for the track. The trophies are 20% lighter than the normal st 60 caliper. Won't get them installed till late February or March.

[will13k7]

I hear a lot of people say the BBK's won't do much for stopping distance, but what they do allow for is greater heat capacity, and that's the main benefit, other than better brake modulation, firmer pedal feel, and looks.

How true is this for a lighter car like the S3?

Are you referring to this kit?

[ryan_sn]

Anybody know if the Stoptech or VWR kit will fit over 18's? I'm debating ordering the BBK kit but I need them to fit over my winter rims.

this ---^. these kits are basically only good if you goto the track... A LOT.

in some cases you will probably lose real world braking distance with this 'upgrade'

This one -

http://www.stoptech.com/products/big...s/trophy-sport

Regarding the benefits -

Yes I would agree that the key benefit is heat dissipation. For street speeds and normal braking you won't see a significant difference. Go with the TTRS conversion or some of the lesser expensive 4 piston kits if you do "spirited touring". Myself, I go to the track multiple times a year and drive at a high level. You will decrease your braking zones distances with a six piston kit. However I'm talking about 140 - 70 or 90 - 40 over and over again,
not the 80 - 0/60 - 0 stats the magazines measure. BBK also help brake modulation as well as other factors that allow you to really go deep into the corners confidently and know what's going on with the traction circle(for those who know what that is)

Another key factor is the tire your running. To take full advantage of a BBK, you need to have something sticky to grip the pavement.

Thanks for the solid feedback. Perhaps I'd be better off doing something like the ECS Stage 1 brake kit and spend the money I'd save vs a BBK on an intercooler upgrade. Keep all the things cool! I only do a handful of track events per year so maybe a BBK isn't worth it for me quite yet. Suggestions for pads? There don't appear to be a lot of options for the S3 yet.

[soulflyer]

As far as pads go, I contacted Hawk and Pagid

- Pagid: they said they intend to have the 'Yellow stuff' for the S3 ready by May this year.
- Hawk: the made it clear that they are not interested to provide their race pads for the S3. Or the Golf R for that matter.

[onequick4door]

If you go up in power(Stage 1 or 2) and go to the track, I would suggest at least getting a 4 piston kit. You will be moving out with stage 2 power.

Pad options - call Carbotech. I'm going to run the Stoptech pads that come with the kit to see how they are, but once i'm done with those. Going back to Carbotech. XP10's in the front XP8's for the rears.

I did run the EBC yellowstuff in Nov with the stock brakes. I thought they had good bite and didn't fade, but where I drive (VIR) there are three long straights that allow the brakes to cool more than most tracks. If I was going to Carolina Motorsports park, I'm pretty sure they would fade toward the end of a session.

[phillyquattro]

Excellent. Thank you both for the tips!

Or you driving in the triple digits on the autobahn. Cars here in Germany like to cut in front of you into the fast lane doing 60 MPH when your doing 100+ MPH on the autobahn.

OEM brakes and a BBK kit.. there is a big difference in pedal feel due to the number of caliper piston increase. The reliability of repeat stops of course is from heat dissipation from the increase in rotor size. And of course there is the looks of the BBK... worth the $$ for that alone. Don't like that our 40k cars have brakes that look like they came off of a Ford Focus.

We just did a group buy on the StopTech kits not too long ago. Majority of the orders were 355mm 6 piston kits. They are a great compromise that gives you a lightweight and compact enhancement over stock and most other brake kits out there. All this said and done at a very affordable price point.

If anyone is looking for a good deal on StopTech Big brakes, shoot me a PM. Check them out on our site here. If you don't see fitment for your vehicle, let me know and I'll get you pricing.

Thanks,

Bump looking for any updates. Looking to upgrade my 2016 A3 APR Stage 3+, some weight reductions already and more to come daily driver that will see occasional drag strip runs. Considering as little as rotors, pads, lines, and fluid and as far as a 355mm and not sure but I guess ST Trophy Street as it is the lightest bbk?

Thanks in advance,

Lusky

[onequick4door]

I haven't seen any calipers lighter than the ST Trophy streets. I have the six pistons and would have to find my numbers I weighed, but thinking it was 7.9lbs or something. The figures above were mainly 4 piston configurations.

How was the noise with the EBC yellow pads? Did you drive them daily? Squeal a lot?

[onequick4door]

I drove them for 1 hard track weekend, then about 3 months on the street. No, squeal, except after you washed the car and let it sit over night. The first time you reversed and hit the brakes it squealed slightly, then nothing from that point on. I thought they were solid pads.

You're right about that. I can get the weights from Stoptech but the Trophy kits shed 20% weight over the regular street big brake kit from StopTech, pretty awesome. stopTech's are also known to be more compact than the competitor, great for wheel clearance.

Any of you guys have Stoptech ST-60's? I'm trying to decide between 355's vs 380's.

[XLR8 Craig]

This might not be too helpful, but the majority of the kits I have sold to S3/Golf R drivers, the difference is split 50/50 The biggest reason the 355mm kits sell well is because they fit behind the majority of 18" wheels. The 355mm 6 piston performs rather well and most don't see the need to spend the extra money on the 380mm. Some like to have their cake and eat it too, which you get with the 355mm. Fits behind 18" and 19" wheels. Ideal for track days and daily driving.

I did see somewhere (maybe I was hallucinating) that someone fit a 380mm behind an 18" wheel. Not sure on the backspace, offset, spacers used, how much grinding that was done... but I swore I saw it.

Thanks,

Greg

[Will@G-Werke]

Anybody know if the Stoptech or VWR kit will fit over 18's? I'm debating ordering the BBK kit but I need them to fit over my winter rims.

I'm running Stoptech a 4 piston trophy kit with 355mm rotors. Fit under the factory A3 18" wheels

+1 and did you have to add spacers?
