i have a luk clutch. it works good. my centerforce stage 1 crapped out on me and I sent it back for a refund. The clutch material was better, but the pressure plate was a piece of crap. A bad weight kept putting a lateral load on my t/o bearing and that which cut a nice groove into my input shaft bearing retainer. Which wouldn't allow me to shift.
I've heard King Cobra clutches are good along with Spec. The luk clutch is basically OEM but feels a little grippier.
