The Panther

I am going to replace the clutch and flywheel in my C4 and am looking for opinions. This is a track car. I am not trying to break the bank, but want something reliable that will last and hopefully help get rid of this vibration I have. Any recommendations?

Call Carolina clutch, get light weight aluminum flywheel and stage 2 or 3 clutch.

Thats what I'd do If I could stay in NCCC grp II.
I have a steel that weighs about the same as the stock DM and a stage 2 clutch ready to go in when I have the funds for the install.

I have a spec aluminum flywheel and stage 2+ clutch. Has worked well so far for me.

nothing wrong with a single mass, they're a lot lighter

just a little noisier, but for a track car, who cares.

I dont have one yet but when I buy a clutch it will be a lightweight Fidanza and stage 2 clutch from Carolina Clutch.

Is an aluminum flywheel going to be a noticeable difference? Any issues with balancing?

I have the stage 4 set up with aluminum flywheel from Carolina Clutch. I do hear the flywheel make some noise but mine is a track only car too so as Brian said, what does it matter?

I wll say that it's a bit of a learning curve with the aluminum FW and the clutch disc I have. Feathering the clutch around the pits and staging area takes a little getting used to. Clutch is either engaged or not, not a lot of middle ground.

Should bolt up with no issues. The engine will rev quicker and you should get a little bit better acceleration with the lighter flywheel.

This is to be expected with a stage 4 type clutch. A stage 2 or 3 should still have good street and low speed manners.

Yep, doesn't bother me but I thought I'd mention it since the question seemed to ask about drivability.

Just bought a 16lb unit from Barnett, in Atl..

What year motor? It matters.

Check out the Sticky on ZF in the Tech section. Lots of options.

Mine was factory balanced based on application. They asked what motor and what we would be doing with the car.

The grabby clutch problems is reported to be the .100" difference between most flywheels for standard application and the DM.

No personal experience, but that's what I heard when researching.

Carolina Clutch set me up with a single mass flywheel and an Exceedy clutch 4 hard years and many track events ago. Still going strong, but I may replace it this winter as PM.
