Learned something just now. Great info man
Resurfaced flywheels FTL with stage3-4 clutchs.
You do know that Exedy/Daiken manufactur ALMOST all the clutchs other than twin discs that are used in the Kseries trans.
The stage 3-4 clutchs from ACT, Centerforce, Exedy and Clutchmasters, all use the SAME pressure plate except for the exterior paint.
ACT hdss, Centerforce, FX400 pressure plates.
But they use different discs which are also from Exedy.
The ACT disc (exedy disc part# HD510D)
The Centerforce disc(exedy disc part# HD511D)
The CM FX400 disc(made by CM's own supplier supposedly(I suspect Exedy))
These pressure plates are a little on the "short side" for the installed height when compared to a stock dimension pressure plate. This shorter height is compensated for by the hydraulic system, but it places the throwout arm and slave cylinder close to half travel already. As you step on the clutch pedal the slave starts moving as well, but before the CMC has reached max travel the slave has . But because the CMC is traveling it continues to pressurize the system causing the hydraulic failures seen.
This can be fixed by adding a washer between the throwout arm pivot ball stud and the clutch case correcting the faulty geometry of the stage3-4 clutchs and places the engagement point up off the floor.

ima be doing this on my CompClutch Super single system
I replace my clutch a couple thousand miles ago but just with stock my jrsc doesn't make nearly as much as you dang turbo guys
well apparently turbo aint that bad man cause my last compclutch stage 4 i removed 2 months ago and was able to sell cause the disk still had plenty of meat left, after so many pulls and passes and all the drag racing not to mention it was ddriven
