Question Removed my burned Spec clutch; which stage it is? pic inside

Like the title says, anyone knows what model it is?
The flywheel is heavy as hell, around 50lbs LOL its an old model, 6 years old at least..it started to slip recently on the juice. There is no part number on anything.Is the flywheel still good too, after resurfacing?

Yup, +1 on the stage 3. Regarding the flywheel, generally, they can be cleaned up (re-surfaced) once. As long as, it's not much under the manufacturer's minimum thickness, it's good. Just, don't ask me the minimum thickness, 'cuz I don't remember. FYI, I've gone .030" under minimum thickness without any flywheel flex issues on 500+ BHP. If you do this make sure to have an adjustable clutch master cylinder or use a flywheel spacer to make up the difference (point being, don't do something like this (under min. specification) blindly).

On spray, you'll want to go w/ a full clutch disk like a 3+; more surface area. Spec can tell you the best recommendation based on your BHP while using spray.

thanks buddy for the info;I was going to check for shimming anyway I was thinking about a LS7 clutch lately for the price and cause my car only sees roll racing and very occasional spray. Plus, I would have a more streetable clutch..but I'm leaning toward a Spec 3 again or a Monster.

I called Spec and they suggest me a Spec 3+ but its outta my price range, unless if I reuse my flywheel..

I used a Spec 3 for a couple of years and I'm going to an ls7. My friends run ls7's and I LOVE the feel of them. It'll hold 525rwhp safely with limited track use; why not have a comfortable pedal too? lol

Ls7 will not hold 500+rwhp or spray well.
