96SERTurbo

I am currently running an ACT heavy duty pp and street clutch. The setup has been on the car for ~27k miles, and now it is slipping badly. It started to slip about a month ago, and under 7 psi it will slip about 50% of the time. My car puts down ~255 hp. I know puck clutches are harsh engagement and harsh on the drive line; all us turbo guys know the problems with 3rd gear. Thus, minimizing drive line shock is a must. I have heard the Xtreme ACT pp has problems with engagement. ACT rates the street disc and Xtreme pp at 308 lb/lbs of clamping. My current setup is rated at ~230 ft/lbs. Does anyone know of other reliable options or have feedback to share?
