Spec Clutches, Slipping No Warranty

[fasterthenrs2]

That is the case, my SPEC stage 3 failed at 340WTQ, that is 425FTQ SPEC was rating that clutch at 460FTQ clutch was driven for only (1800 miles witch I did put on in a less then 6 weeks) no warranty.
That Engine did get blown up by unprofessional tuner …
Build another one a lot of help from 034, thanks. SPEC sold me an stage 3 plus rated at 630FTQ, I did go easy on that clutch for 1800 miles with 450FTQ braking in build engine ETC. It did hold up on a dyno with 584FTQ, soonest I did hit the street freewheeling. NO WARRANTY 3 days over time limit warranty. WTF

Spec gave me mixed feelings over the years. In the black coupe the spec stage 3 hold out to the very last day i drove it. No problem there what-so-ever
In the blue coupe it slipped almost instantly with a 3+ kit. Spec claims that they send the wrong plate, it would be to thin....
I've just installed a spec 3+ on an RS4 and including this one all the spec clutchs I have had/driven, have yerky take off characteristics. Now I'm at point to decide about a new clutch, and i have hard feelings about spec....

I have not dealt with spec so i don't know there claims as to wear and life expectancy.
From looking at the pics, you all are running ceramic clutches!?
They only last may be ten races in a race car! no traffic work there, they are not designed to slip on take off. more of a switch, on or off.
No way would I run such a set up on a road car!
You need a twin plate organic. Anyone tried Mcleod in the states, I have one for my Mustang, twin plate, can deal with 1000 bhp and is organic.

MOst of the racing sportscars I run/prepare try to keep to an organic, the pain of ceramic is just not worth it. All the dust sticks like cement to the input shaft, stops the plate moving as it should.
Just a NO NO on the road.

Yah

That is what I think, on a street with fidanza fly., every take of steal insert gets hot starts to warp etc.
SPEC is stating 3 and 3plus is the best setup for street, long lasting etc. (Hate Layers) Every time I called them after they product failed they answer was try this another stage setup it will cost you another 700$

I've been hearing good things about South Bend Clutches on Audi-Sport.net - anyone had any experience of the DXD 'Organic / Feramic' clutches?

[fasterthenrs2]

That is what I got now, it doesn’t slip at all, and Andy was very helpful. Thanks South Bend.

Well, thats very interesting! Can you suggest a clutch for the 3B flywheel?
Incidentally my Spec 3+ seems to have bedded in nicely now, its even fairly smooth on takeup. At least its a continuous ring and not a paddle.. I would far prefer an more normal feeling clutch next time though and if an organic can be made to take the torque then thats what I want.

Here is what Spec say about the stage 3+click , they call it a carbon metallic friction material BTW. They used to say, on 034 site, "you will not blow this clutch" or something like that, that claim is now gone..

Is SPEC laying??

Stage 3 was freewheeling at 340WTQ, 3 plus 467WTQ, way under SPEC provided figures, Is SPEC laying?? ???? To up sell they product.

well a rough assesment is that 467at the wheels means 580 at the flywheel.when i bought spec 3+ it was rated at 550hp but at the 034 web site it never mentioned if it was wheel power or flywheel power.I always concider this as flywheel just to be sure.

now im running a setup that is close to 400hp flywheel and possible in a little while will be 420hp meaning that it will not be more than 350wheel power.This is far away from the power that the stage 3+can handle.
Up to now,other than the jerky movement as others have mentioned above i see no problems with the spec so far.
If they do come up,then sachs organic will be my choise which are said to handle 52Nm of torgue(accordiing to sachs) but they seem to handle more than that.

[A80Avant]

also im running mine with stock dual mass flywheel setup.i dont know if it has anything to do with it,but i read somewhere that the dual mass,tends to absorb more stress from the disc,thus allowing the disc not to be overheated or warped..seems logical

I have a spec stage 4 clutch in my golf. done 425miles so far, but it grips ok. I run steel flywheel, ally flywheels are, in my opinion shlte. the dont get rid of heat from the clutch.

The stage 4 clutch is very on/off but it is taking the torque. Time will tell as boost is about to get turned up on saturday when Doug and I do some more mapping, only running 1 bar for running in.

Will be taking the gearbox out early next year to fit an LSD, so if the clutch is still alive, with take it out and inspect it.

Have a read of Spec's Warranty Information. It says it all really.
