I put an exedy Twin Plate (new) clutch with lightened flywheel in my 33GTR yesterday. My old Heavy Duty Exedy Single was stuffed!!! had nothing at all left on it when we got it out... value for money on that clutch
The new twin plate is great from what i have driven so far, no rattling (yet, will happen when it gets a bit worn i think)... bites hard, bit heavier under the foot, but still very drivable.. I'm happy with it, makes my car feel tougher...
Nismo use the same exedy twin i put in...
