Im doing an engine swap on a 2001 Audi A4 and the clutch was slipping before so im going to change it while i have the motor out.
any suggestions?
want a performance clutch or a stocker?
not all out performance where its hard to drive, but something better then stock.
triple plate? 
i have had good luck with ACT.
ECSTuning.com sells the (high quality) OEM clutch for my VR6 for a ridiculous price. I paid $165 shipped for a new Sach’s disk, pressure plate, and TOB. Not sure about for your car, but take a look there. Shipping was fast too.
+1 for ecstuning
