ive got the spec stage 2...about 1500 miles since i installed it, and i love it...it engages a little harder than stock, but not enough to make it not streetable...its a great clutch in my opinion, 100% satisfied. my car has well over stock power, it'll outruns ls1's(2000 SS, and a 98 ws6), and im about to install 4.10's, so we have close to the same setup, and i fully recomend the spec clutch

 

I have 311rwhp & 324rwtq on my 98ls1 and you are saying b/c of your clutch you can outrun me? Not attacking, just asking if the clutch made that difference for you? If so I need to order a performance clutch. Mine is slipping.

 

i smoke ls1's all day long im about to redo my lower end of the engine may make it a stoker

 

had my centerforce for about 30,000 miles no problems, and i spray a 125 shot through 4.10's and a set of stickies!!! no slipage at all!!

 

We've got a new Drivetrain forum which includes talk of clutches. I'll move this there for ya!
