Don,
I guess you could go with many different set ups.. I wouldnt recommend ACT SS. They say its rated around 400.. But I don't think so.. I think people had better luck with ACT pressure plate and 6 puck plate..
Or SPEC.. but some had some issues with their stage 3.
I'm about to try one of Exedy clutch. I'll let you know how that goes...
Also, I have a ACT MZ-011 - Heavy Duty Pressure Plate. Its used and needs a new clutch plate.. I'll sell you the Pressure plate by itself for 175.. This way you could just get a new 6 puck for like 125.. and have a kit for 300
