Those of you with turbo boosted 3.7's....what are you running for a clutch kit? I've been doing a lot of research and I've been looking at Auto Mafia Racing's twin disc kit (pieced together with a McCleod RST/lightened steel flywheel with braided line and a slave spacer) or..the Spec stage 3 single disc with aluminum flywheel. Looking for input, I can't make up my mind.
