I actually run an autozone clutch, I want to stay away from realy strong clutches right now on the stock t5. The reason is well I want the clutch to be the weak link not the trans. I would rather blow a clutch that has a 100% lifetime replacement than a $1,000+ trans. Now when the t5 does blow and I get a tko well I vote a centerforce or spec. I have had two buds blow 3 king cobra clutches, one shatering the disk.
Oddly the autozone clutch lasted 3years with 125 shot of n2o at the track, alot of track runs. and me not being easy on it at all, in fact the only reason it failed was the input shaft bearing failed causing uneven wear on the disk/plate.
