Well, in my eyes just because its not a huge name brand doesn't mean they aren't good parts. I mean I ran a hypersingle on the sr, and would love a similar clutch.. But as I said, I do not have 1500$ to drop on a clutch and I need to get my car back on the road.
I have read a lot of good reviews on Z1's new clutches, afterall they are a Z based company.
