I have ran a CenterForce Gold (which was a joke, but then again at that stage I really had no clue what I was doing) it didn't last long, then later a Dual Friction (which I didn't have long and smoked at Fun Ford Weekend back in early '96), then I ran a Zoom Kevlar (which I was pulling the tires with, running 11.4s, late '96). In my present car, PBF put in a RAM 900 Series clutch (on a bone stock motor though) when they installed the Tremec TK500 and Lakewood Bellhousing. That clutch grabbed hard, but there was no slipping it and I hated driving it on the street. When I later pulled it out to put in another Zoom Kevlar, I noticed the Surface of the pressure plate had alot of cracks in it. I was using a billet steel flywheel at the time too that PBF had added. Later I heard that the RAM 900 pressure plate requires a special flywheel other then a billet steel flywheel. That may have been the reason why I had driveability issues, ie. lots of chatter and no slipping.

Just some info, so hopefully if someone has any info to add to my experience or has more info it will help you out.
