Spec 1 is more than enough for NA stuff. . .

I think you should skip 2 all together and go to 3 if you plan on heavy FI stuff. . .hehe, that's what I did, of course it's a fast, sharp engagement, chatters if I don't engage it right, and is pesky as hell, but once I have the boost on tap, I want the assurance of a clutch that can take 400+tq. . .
