I had this on my car 3 years ago. I had it in there for UNDER 1,000 miles and blew the transmission up and decided to go with a C-4. This is Ram billet steel Sfi 28 oz imbalance flywheel(157tooth), and 900 series pressure plate and disc 26 spline for Tremec TKO. My car made 625rwhp and 650rwtq and this clutch held. Never ran slicks. This stuff is in very very nice condition. I've had it laying around...now i'm unloading. Fits 86-95 Mustang...i'm sure it fits many other applications. Haven't figured a price yet and it will probably be on Ebay shortly. PM me if you are interested.
