I have a 96 audi a4 2.8 quattro. My clutch is slipping I was wondering what is a good brand for a clutch kit? Is it advisable to purchase a stage 2 clutch? I've seen F1 racing, sach, exedy, SPEC clutch kits are any of them good? I would love to get my hands on a Clutchmasters clutch kit but that's out of my budget. any feedback would be greatly appreciated.
