To answer about the hybrid disc. I had a stage one but they are available in every disc compound they produce.

I have two of these, but can't comment yet. Then one at LR is installed but never driven. Bought that setup so long ago I can't even remember what type it is. It does have Spec lightened steel flywheel an pressure plate though. The CA car has all the latest with the all aluminum versions but I have been too lazy to install yet. Hopefully I can give you an update soon!

This is what the spec clutch disc looked like when I pulled it out of the 968 engine. Note the cracking and how the friction ring is not well attached to the hub.

I have a Spec stage 2+ in my '88 TS and it has performed well over last two years since install with a Fidanza Aluminum flywheel. I did have a problem with chatter during uptake in reverse and 1st gear, which has gone away after installing new cv joints and filling the stock trans mount with polyurethane. I track my car regularly. Mike

I had a spec 3 hybrid with the lightweight pp, it was smooth to drive but the organic side of the disc started to slip after 1 summer so i changed the organic side to 6 pucks also.

yes it´s a little bit trickier to drive slow with it and i don´t like stop and go at to many stoplights in a row ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
Or did you mean the full metal disc?
no corleones car didn´t not shatter like a 6 puck disc at all

Update:
Loving it still! city driving, mountain driving, full throttle driving. Doesn't chatter.
occasionally it will but with some smooth engagement you'll pass it very easily.

I've just decided to go with the Spec 3+ after reading these reviews (and many others). If I didn't need the clamping power I'd consider something more "streetable", but the final destination of this car is the track. It's an '89 944 S2 waiting for a turbo charger. I just bought it (with a bad clutch) and want to track it before the turbo install to look for other kinks that will need attention. Didn't want to do two clutch jobs in the same year...

I had a spec stage 2 on my 924S with their light weight flywheel and pressure plate, the clutch was great on the track, clean shifts, good engagement... It SUUUCKED to use in traffic or stop lights, it didn't like to be ridden and would shudder. But once outta first gear it was great.

Any clues? '89 944 S2, stock drivetrain.

Given the number of people who've complained about it's performance, I've decided to not experiment with an aluminium flywheel at this stage of the build, instead I'm planning to resurface and balance the stock flywheel. I need to be able to drive the car safely between my shop and the track, which is only 50 miles from me (Laguna Seca).
I have heard success stories from people who've used 16lb flywheels, They're hard to find, one person described them as "hen's teeth". Some of have said a decent lightweight FW for the S2 can run as much as $2000 if purchased from someone who really understands the engine. That's a bit too exotic for me at this point.
