diy high bias torsen diff mod washers. kits available inside.

[Ian@Absolute]

available here is a set of washers which will turn your 2:1 center torsen differential in to a 4:1 center differential.

in case you are wondering about testing: i have been running this mod in my personal car for ~3500 miles.
i have done donuts on closed courses. been to the drag strip. and drive my car 120+ miles per day. 5, sometimes 6 days a week.

we are selling these washers for an introductory price of $155/shipped in the 48 states. international is available but will cost a few extra usd dollars.

we are also a stocking motul dealer. gear 300 oil is available for an additional cost. my gearbox took 2 liters to refill.

if you have any questions feel free to post or pm. or if you are interested in purchasing a set please pm or email [email protected]

*note: ^ this stuff helped alleviate a lot of the vibration caused by the
install of both stern's power ring and rear diff bushings in my personal car.

$155 for washers?

[lil' is 300]

$155 for washers?

My thoughts exactly.

[FrimmelNoJerz]

I'll take six!!!

[Johnny Bravo]

How do you ensure the bias ratio after you reassemble the diff? do you have a friction meter? or are we just assuming that the coeff and preload of the washers, will do and the tolerances are close enough? I don't know how stasis ensures their bias either? Am i asking the wrong questions.. what can you tell us?

Are they just washers? Obviously some thought ( at least i hope ) has gone into the design. what is the alloy? they are not your off the shelf galvanized steel washers? Explain more, educate us. :) what is the stock friction level? what is are theses?

Can you explain how to ensure that the Diff is properly timed, so that when you go for a drive you dont frag your housing?

[lil' is 300]

I would assume at the very least these are precision machined. But still...$155? Does it come with free lube?

Dude! You are forgetting those black bolt looking things are included also.

[lil' is 300]

Scary thing is that this is the "introductory price".

[DefiantS4]

Wait, so to go from 2:1 to 4:1 all you have to do is stick some fancy washers in your differential? I thought there was more to it than that, like new gears and so forth.

[BastardS4]

What the hell do you think stasis has been doing with their 500$ center diff mod??

[Europowerhaus]

Redine Gear oil is whats up!

[AB18]

Geez, thats unreal. 155 for a set of washers downright funny. I can't believe statis does this for 500, AND takes your stock dif. Funny.

the tolerances are perfect. the machinist does a very good job.

they are thru hardened steel washers. i am not sure of the exact material. they start life as thrust washers and then are machined.

the timing of the diff will be correct when you reassemble because you are not disassembling the entire diff. the parts only go back together one way.

http://www.torsen.com/fsae/fsaefaq.htm

One of these factors is the friction coefficient of the washers, which the side gears thrust against when torque is applied. We use a variety of different washer types to adjust the TBR. Higher friction washers include plain steel, steel with nickel plating or FNC heat treating, and hardened bronze. To reduce friction, we also use needle bearings as well as washers with a Teflon-based coating.

to the people questioning the price... http://audizine.com/forum/showthread.php?t=206325

Go to a machine shop and ask them to grind you two thrust washers. this isn't something that is simple milled. They are PRECISION GROUND. I'll be honest, once I had the dimensions I sent them to the guy that does all out tooling. I was quoted $135 for materials, labor and having the parts heat treated and polished. Yes, ordering in a large batch cuts cost since the set up time is reduced. The labor is still there.

[Alex@VAG]

Before bashing this, anyone looked at the price of materials and machining these things? The s4 market is a very small and cheap market, if you bash everyone that comes with a new solution, s4 will remains unreliable, overweight, understeering pigs. How about you wait to get a little more info before saying it's overpriced. I am not affiliated in any way with absolute but just think that you guys are quick on the triguer. 155$ shipped, that no even 2 tanks of fuels in Montreal, take the bus 2 days and tada won't even show in your budget!

[Ian@Absolute]

thank you.

[Dimcorner]

So i can technically come over the store and pick a set up?

[Ian@Absolute]

yes.

These are the same idiots that are bashing about stainless steel manifolds in your Gt kits Alex.

`` 2000$ + for manifolds ?, I can get them on ebay for 300 $. After all, it's only stainless steel and a few quick welds``

LOL

New things into the S market is always a good thing for sure.

Ian can you find out what kind of material is being used for these??

Cheers

[Ian@Absolute]

i will try to find out tomorrow for you.

Honestly though with all due respect you really can't say anything about people complaining about prices. Afterall, you are trying to sell your GT kits so you're not really speaking for us since you'd want to sell your kits at a profitable price as well.

I'm not speaking of the idiots you were referring to about bashing kits and stuff. I personally think lots of the kits are well made by shops and don't doubt for a second that there have been tons of R&D done. But it's no secret that the prices are hiked up just because we are all Audi "s4" owners. But that will change soon since these cars are going to 3rd and 4th owners. Original owners have moved onto RS4s and RS6s and much more expensive cars. Obvious price hiking for parts on these cars isn't going to survive for very long. I think all of us will start seeing some real competition for parts and prices soon.

Price hiking is part of making a profit; but with that said alot of people dont understand that to have someone machine a set of high quality pieces costs a good amount of money and then he has to turn around and try to make a profit as well. Unless you have a CNC machine or another piece of equipment in shop its hard to get prices to the rock bottom low that everyone wants because of all the maintenance our cars can require if not taken care of or just need it due to higher mileage.

I would rather pay 150 than send it into Stasis and have them do almost the same thing for $500.

[F16HTON]

By no means I am putting down Ian's product but when STaSIS installed my high bias center diff I physically watched Ford (their mechanic) walk over the the parts bin, pull out a bag and lay everything out on a workbench.

The STaSIS package included planetary gears, washers and pins. I do not know if the new gears were necessary, but they are part of the STaSIS installation.

The installation did look to be pretty straighforward however, they put the car on the lift, removed the propshaft from the tailhousing, secured it to the exhaust, removed the tailhousing and then the center diff, put the center diff on the workbench, disassembled it, repalced the gears and the washers, and reinstalled it back into the transmission.

Since I was already using Motul gear oil, all they had to do was top it off, may have taken six or seven ounces.

oh cool, lets compare some washers to manifolds, that sounds like a great idea

i would much rather "waste" or give my money to stasis based on principle, these washers are a RIP OFF no matter which way you slice it

Well then.. I guess thats why stasis is still in business.. Good to hear not everyone looks for alternatives to save money.

The manifolds are an example of a custom product being made.. same as these. *have to machine them and that takes $$

Case in point. More products for our cars mean more options for people. More options means not having to waste you money on overpriced products that include a surcharge just for a brand name. I dont mean to bash StaSis as they do make great products but they are just alot more $$ than I am willing to pay to get the same result.

I'm glad some of us understands the cost of machining or custom building one by one examples.

[Europowerhaus]

a cnc mill still wont precision grind like these washers are, I have never seen a cnc grinder so maybe I'm wrong, but I dont think the prices are that high but eventually these will be dup'd just like everything else :(

[GURUMAN]

I was selling a full kit, custom everything, Vbanded including fueling for half th price of the competition. If there was a 10%to 15% remaining towards my pockets, bro it's the way life works in general...

[Europowerhaus]

or maybe these are in fact duplicates of Stasis, doesnt matter either way because everyone does it, biz is biz period

I really don't think price are hiked because they are s4's. Parts will cost more than some other cars because it is a very small market with a lot of competition. No one will invest in mass producing something, because you'll never sell enough to make it profitable at a low entry price. It's not a ferrari, it's a freaking vw but it's a bitch to work on and they where sold for 3 years to a limited audience. Of course parts are going to be more money than a civic.

If I was only reading these forums I would stop selling anything s4 related. As soon as someone brings something new, he gets bashed like there's no tomorow and people want to copy his stuff for a lower prices. Thank god I get to speak to s4 owners that don't have that attitude that keep me willing to invest time in these cars.

[Wizard-of-OD]

I doubt...

But it's no secret that the prices are hiked up just because we are all Audi "s4" owners

Incorrect.Prices are Hiked up to cover overheads and due to demands.Ever tried buying bulk?

I am tired of people TRYING to compare the Audi market to the Mitsubishi or Honda communities or whatever else is out there.
You want to hear a sad scenario?Edlebrock when they cast the Victor X manifolds they do batches of 1000+...think about that for a minute. 1000 MANIFOLDS....compared to APR that does a batch of probably 10% of that.It may take APR 3 years to sell all those manifolds but I guarantee by the end of the season Edlebrock would have sold all and its not because the price is cheap.Its because as much as we laugh @ the ricer boys or whatever else ,those boys pump the money where it belongs.Same for the Mitsu crowd and the Subaru crowd.

Walk on over to US (the VAG owners) and everyone calls us cheap.
VAG owners dont seem to realise that VAG tuners HAVE OVERHEADS.We do not run charities....we run businesses.Businesses take time money and effort all so that we can produce parts that YOU the end user will like and buy.

But then of course there is that VAG attitude...

"if he can make that part and sell it for $X then why cant I?,let me try stealing some of his profits"

As for these washers being too expensive.Well considering that Ian is not making 1000 pieces I can see why they are.Either dont buy them or move along...dont complain about the price unless there is an alternate solution.

[k0mpresd]

I really don't think price are hiked because they are s4's.

to further prove this point..i have gotten a much more respected responses from b5 a4 owners.

and just imagine how cheap they are. i would know. i am one.

edit: thanks issam

[casawhites4]

hmm, is this worth it...honestly..

[k0mpresd]

this mod is for the performance oriented owner. it will change the handling characteristics of the car.

is that you or something you are interested in ? if so, then yes. it is worth it.

[Poopie]

It works pretty good. Drifting in the rain is fun when you push. If this a daily car you don't really beat on, you won't no the difference. If you go into a corner too fast and understeer, the power sent to the rears makes it easier to correct. The mod only takes effect when the tires spin at difference rates.

thank you for this post. this one seemed to come from a totally different outlook than your others.

[Boris]

I think some people are overreacting. This is the internet. When I told him about the first tour his brother did in Vietnam, he did not believe me.

I told him, He came back a different man, that he was spooky. Fwiw, I think your out of line , you're criticizing him on something he can't help. Being in Da Nang is alot different than being in Cambodia or the golden triangle doing who knows what for who knows who. I would cut him some slack man.

[F16HTON]

thank you for this post. this one seemed to come from a totally different outlook than your others.

My opinions about the high bias center diff come directly from my own personal experiences. I fully respect that you are offering an alternate solution to STaSIS, however each of the approaches taken are different.

Until you mentioned it, I did not correlate that Ian@Absolute and Kompressed were one in the same.

Maybe others will understand more about this modification if you are able to post up some technical information or videos similar to Jay's blue glove productions.

[AB18]

I am not saying the market prices for turbochargers, intercoolers, and other kits should be cheap like other cars, but these are freaking washers. I don't know, maybe its just me, but i find it hard for myself to spend 155 for a set of washers. Maybe to some its worth it, more power to them.
