Something so easy as picking a clutch is turning into a difficult choice. I recently broke my stock input shaft and now that I'm upgrading to a 26 spline input shaft I need a new clutch. My Cobra has a ported blower putting down over 500 rwph and about 500 rwtq. The car sees both street and strip use. I use slicks when I go to the track, I'm not sure if that's relevant or not when choosing a clutch. I had a Spec clutch and flywheel when my stock input shaft broke. I liked the Spec clutch but I don't know what stage the Spec clutch was because it was put in before I got the car, it looked like it was a stage 1. A twin disc clutch would be nice but they're a bit too pricey for me so I was looking at the Spec 3+ or the CenterForce DFX. I also plan on reusing the Spec flywheel. What do you guys have and what would you recommend for me?
