ACT with Fidanza is also a great setup. Drove one and I really liked it.
Does the Exedy single come with a flywheel or no? I'm assuming not for the price, but has anyone have experience with the Exedy single and Fidanza flywheel?

Please post.

A good quality cerametallic will hold about 25-30% more torque because of the extra friction, with the tradeoffs of rougher engagement and possibly increased wear on the mating surfaces. I wouldn't say quicker wear life, but increased wear on the flywheel and pressure plate and probably less on the disc.

We have found that the Exedy stage 2 with a CCI flywheel work great together. With that said, I am not sure how long it will last since none of my customer has more than 10k on that clutch yet.

From my past experience, ACT makes good clutches but the pedal feel is just too harsh for me.

Thanks,
Tom

I know on gen 2's act clutch with their hard thick pressure plate forks caused most of crankwalk...4 of my friends all gen 2 turbo had act and they all had crank walk lol..Maybe the motor had something to do with it also but I have never seen one crankwalk on stock clutch..Maybe that isnt the case anymore..Has there been any redesigns on the act clutch or does it still have thick clutch forks?

I have heard of crankwalk on stock clutches and even automatics believe it or not. It is definitely an engine thing, but certainly a heavy clutch is only going to make it worse, especially during extended high rpm launches, etc where the engine is spinning real fast under high thrust loads.

With the CCI flywhee, is it too light where you need to double clutch on up-shifts? That is one thing I am worried about with a lighter flywheel. I don't want the revs falling off so quick that I have to either power shift all the time or double clutch on upshifts.

Bump for new clutch. What about the new RPS clutch that is in the same class as the first two?

what about the RRE Dont they offer a nice setup too, and why not shave down the stock flywheel and make due with that ? No a good idea either?

How about a custom setup with a ACT or Clutnet clutch? I have had both with no issues on other cars making more power

I nneedd a clutch REALLLYY bad So any info would help!

I don't want to take up any more bandwidth on the subject, but I would like to continue the conversation with you about organics and other materials if you have time. I am going to be out all week at SEMA so maybe when I get back. Drop me an email if you would like to continue or maybe give me a phone number.

No argument, just giving another member some advice from my past experiences. I've used the product and was just letting him know that there is a reasonably priced and superior alternative to organic.

No real difference IMO. They are performing the same task. The difference comes with how much power it can hold (or transfer to the trans) and how harsh the clutch engages which is controlled more by the disc than anything else. Harsh engagement will transfer the power over a shorter period of time which is more like an impact than just torque transfer. Obviously impact plus torque can damage parts more than just torque alone.
