A98COUPE There is a couple of things I learned with any clutch and problems
1 Clean engagement, all surfaces have no fluids,dirt, or film on them
2 Break in is very important to get a good gripping surface of both flywheel and pressure plate. 500 miles.
3 Quick in and out of the clutch pedal, NO RIDING it.
4 Air gap clearance between .035"-.050" with clutch pedal pressed in.
5 Clutch pedal stop. The pedal doesn't need to go all the way to the floor. Pedal should have about 1" of free movement before engagement of the slave cylinder. If you have a HTB thats a different story and need the correct clearance to not wearout the bearing permaturally.
6 Racing the car, goto DOT 4 fluid, if not either DOT 3 or fluid designed for hydro clutches
7 Does your disc have a spring hub? This helps absorb shock load to the drivetrain. If not the shock load goes straight to the trans or rearend. Which every the weaker part is will break first.
8 Forget the numbers of what Mcloed is using. This info is for min 3,000-3,500 pound cars. Your car is what 2,500 pounds. The only reason for running a higher pressure plate and solid disc is racing on the track, mostly 1/4 mile and 5000 rpm launches.
9 For 7 years I ran a 452 motor with 368/448 HP/TORK. Ran a 2,400 pound pressure plate and organic disc. No failures or slipping problems. Wear on flywheel was min. I have gone to a 482 motor with 540/620 and this motor is too much for this clutch. I also run a softer tire. Brent sold me a Street twin. It holds my motor, no noise, and should last 10 years of auto cross and road racing on the track. I run GM input shaft trans. May be easier to get clutches for this setup. My flywheel was custom for either Ford or GM pressure plate bolt patterns. Figured if the disc or pressure plate broke, local store would have an 11" clutch in stock to repair at the track and keep running.
10 Last note, until I went to the Twin setup, I wanted the clutch to be the breaking part of the drivetrain. It's the cheapest and easiest to repair. The higher pressure plates and solid discs are not always the best for your driving or cars drive train. Good luck Rick L. PS bigger is not better always except in cubes.
