I'd like to reinforce this from my recent clutch job.
I purchased a used act extreme pressure plate and street disc. Low miles from a member here.
I purchased a brand new Fidanza flywheel from the factory.
From Mitsu I purchased a brand new tob, clip, pivot ball, and fork.
I have a new clutch master less than a year ago and has no leaks, slave is older but has no leaks.
I noticed that the new equipment does not sit as high as the old equipment, I think its because the oem flywheel is rediculously thick.
I read alot about shimming with an aftermarket setup but I also noticed people on here did not support that theory.
I ended up shimming with only one washer vs the reccomended 2. I was able to get my car to disengauge bairly but I could drive it. Slight grind in first and reverse. Went with the extended rod, problem solved. Hope this helps others.
