1992 Clutch

Ok so soon it is gonna be time to replace my clutch. What do you guys recommend for a mostly stock car? Also my car has had a "blue tag" brand new transmission put in it so what year clutch kit do I need now? 89 to 93? or 94-96? Im assuming it is because of the different flywheels so I think I would still use the clutch kit for a 92. So please let me know who has had good or bad luck with clutches. So far I am leaning to a company called SPEC. They sell a stage 1 clutch for about $360. Thanks!

Some people have had problems with SPEC clutches, particularly with the pressure plates being out of balance. Lately some have claimed that SPEC fixed the problem, but, personally, I would stay away from them.

For my clutch, I went with a stock Valeo replacement. The expensive part is deciding what you are going to do about the flywheel: get another dual mass, or go with a single mass (either f-body or aftermarket).

Use a 94-96 clutch set, not the early one. They are identical except for the slightly smaller throwout bearing that fits your blue tag trans.

That all depends on who you ask. The flywheel is two parts and basically floats on springs and bearings to insulate it from crankshaft vibrations, so it wouldn't be machined like a normal flywheel. The shop would have to secure both halves together somehow before milling it down. And some think you can't take off much of the surface without screwing up your clutch adjustment, which I have a hard time believing. The other thought is that the flywheel spring wears out, so reusing it would make as much sense as reusing your pressure plate and throwout bearing when you do a clutch swap. Except those are cheap, a flywheel isn't.

From my experience, the flywheels last about 120k miles... more or less.

And yes, alignment becomes an issue if you take too much off of them.

I guess a lot depends on mileage and if you race it. Racing will eat them faster.

Think of it this way, those springs do the same job as the springs in conventional sprung hub friction disc... and I have seen those pieces come unglued, literally. There is a lot of torque and driveline shock being absorbed.

As for SPEC - stay well clear of them. Fitment is another problem. I am actually suprised they are still in business.

Alright thanks for the help. My car has 70,000 miles and I dont think it was abused too hard so it looks like i will be going with a delco stock clutch and trying to find a good shop to resurface the old flywheel.
