ACT does not seem to want to make an Xtereme pressure plate for our cars. I remember a while ago Graffz told me he used a Z32 pressure plate with his 250mm flywheel. The clamping force on the Z32 pressure plate seems to be much higher, probably because they have stiffer stock pressure plate and a clutch booster equipped system. He also told me the Z32 pressure plate bolted right onto the 250mm flywheel with the same bolt pattern.
They use the same clutch discs as the 250mm Z31 (87-89T), so the clutches are really interchangable.
Using their street disc and a Z31 pressure plate gives 360lb/ft of holding capacity, while using a Z32 pressure plate ups that to 432lb/ft capacity.
About the same for the 6 puck, using the Z32 pressure plate takes it from 461lb/ft to 553lb/ft. (the 240mm for the Z31 is rated at 512lb/ft).
So, if I'm right, it would only take an additional 22% clamping force on a HD Z32 PP to make a 250mm street disc meet the holding capacity of a 6-puck. None of the disadvantages of the 6 puck, but the same holding potiential.
Ugh... So does anybody know of an inexpensive high clamp load 250mm Z31/Z32 pressure plate?
