What kind of power are you pushing?
How good are you at driving with a clutch?
SPEC makes a SPEC 3 or SPEC3+ which is an all around good clutch for high power engines. The center hub is springed for street driving. If you are good at driving a springless clutch then you can get the SPEC 4 or if you want they make a SPEC 5 which is more of a pure race style clutch.

Springless clutches take a little more finess when driving on the street because you don't have the springs cushioning the bite. Think of a springless clutch like a true on/off switch. It is engaged or not engaged that is it. Very little slippage. But when racing on the strip, You have full pressure which makes the RPM/power during shift have near zero loss due to slippage/cushioning of the springs. Takes a little bit of getting use to it, But for getting max power quickly to the wheels it is the best way to go.
I am using a 6-puck SPEC 3 clutch. (They didn't have the SPEC 3+ back then or I would have chose that one) I've had it since I did the swap 5+ years ago. Have had no problems with slippage. Car has seen the strip, road courses, and street driving. Never had an issue.
