Cup Fly Wheel

Hi everybody a new member from Australia.

I have found this site really informative especially the info from Loren re 04 suspension alignment settings.

I compete in Tarmac rallys and have used both MK 1 and now a MK 2 Gt3.

I have just decided to change the final drive to the 4.0 / 1 as it makes the car far more driveable and much quicker in acceleration. My MK1 had this conversion and I do recommend it unless you use your cars to cross the country.

I need some help however regarding the clutch. I recently fitted the Cup clutch (puck type ) and matching flywheel. The car however is now not nice to drive as the clutch has no springs and shudders on slow engagements as this type does tolerate any slippage.

I want to keep the flywheel but change the clutch for a more forgiving type. The problem is the RS or MK1 CS type does not match to the flywheel as the contact face on the Cup flywheel is about 70% of the std single mass flywheel as it is suited for the puck type clutch and is much lighter than the RS type.

Does anybody know where I can get a performance clutch that is more forgiving but matches the Cup flywheel. Please help if you can oherwise I will have to go to a complete RS kit.

You would have done better to install the flywheel and clutch out of the 04 GT3RS street car. Its a single mass flywheel (~20lbs lighter than stock) and a spring centered clutch. I just did this upgrade on my 04GT3. The engagement is similar to stock and the engine revs much quicker. The cars really should have come from the factory that way.

Gert @ Carnewal.com has all you need.
