Ok, pulled the flywheel off today, tried to mesure the best i could, hard to hold that thing up in the air and take a pic at the same time. lol.........not the best pics but it shows im a little short of a inch thickness, bought this flywheel new in 2010, so far by looking at past pics ive had, its been turned twice........ i measuraed in a few differnt palaces so its off a hair here or there so this would be the 3rd time, gonna get a new pp and clutch, been using the center force clutch for a long time, but would like to hear any other opinions on a new one, if you guys think doing this for the 3rd time is ok, might try it, otherwise im thinking of just getting a new one.

I've been recommending SPEC and/or ACT. I lean more towards SPEC, they are less expensive for one, and have firsthand knowledge.

I would recommend the Stage 2+ :

Their' website leaves something to be desired, but I always just use a 70 GTO 455 as the app and be done with it.

For ACT, someone here mentioned they used the full organic one, which is the GM4-HDSS:

ACT doesn't really give a TQ rating, they just comment it being X% more than 'OE', so I would probably suggest the next step up, which is the GM4-HDG6, but again, I have no personal experience with these, going by what others here have commented on:

Also note, it's not often you get the correct bearing/ bushing or throwout with 'kits' for Pontiacs, and you need to be prepared to check and possibly buy a separate one.

I am very abusive when it comes to clutches/manual trans', and have tried many. Plenty of opinions here, so choose wisely.

SPEC does a lot for modern muscle, and use hybrid materials, while many still use the same 'ol same 'ol. Some of the high power modern muscle guys around here use SPEC, and have recommended them to other modern muscle guys who also are very happy with SPEC. Was how I came across them.

Take it to the machine shop, let the expert tell you if it's suitable for another cut.

One would think that the flywheel manufacturer would have a "minimum thickness" spec, just like for brake rotors...although I've never seen one. I also haven't been into a manual transmission since the '80s, either. Have you contacted the flywheel manufacturer to see what they suggest?
