My clutch is feeling the effects on my CTSC NSX. Anyone have any firsthand experience with aftermarket clutches. Spec? Comptech Powergrip II? RPS? ACT? Not worried to much about pedal pressure, as my stocker feels very light (I'm not small in the body department) Long term thoughts and or ideas on which one to put in once? Would you go the same route? :smile:
Thanks in advance,
John
 
I have the ctsc w/the power grip and have been extremely impressed.:biggrin: Clutch feels very capable handling the extra power and no fade when pushed. The lightened flywheel is also a big plus.
 
Sachs racing Germany built a custom made race clutch for me - using the CT light flywheel I already had. It sure can handle a lot more power than my N/A engine has (it's also the first that survived a racetrack season without any signs of wear) but it is not very comfortable for street driving (no damper springs, digital pedal).

Expect a price in the region of other aftermarket clutches. Details for U.S. customers are here .
 
Thanks for the info Wolfgang. I am more interested in a streetable clutch, versus a track one, which is more of an on/off switch. Enjoyed your version of the "nsx files"
Take care,
John
 
I second the power grip II ,the only caveat is my first one only lasted 25k miles,it failed at the glen,going into turn 6,I have it replaced with another of the same,I must say though that the newer clutch plate had more springs than the old,so maybe sachs did some updates in the interum.
 
Hi John,
For my CTSC, I thought I wanted a "heavy duty" clutch so I chose the Exedy single disc street clutch and switched out my barely used OEM clutch at 19k miles. That thing grabs very well but that is exactly the problem. Since there is no slip, launching the car smoothly has been a problem. If you are in traffic, that thing chatters like hell. I can't wait to use up that clutch so that I can go back to stock clutch. I don't think it is going to be anytime soon. I might just take the plunge to spend that $800 labor to just get it done. Andy uses the stock clutch in his BBSC NSX and he is very happy with it.

I drove a friends 95 NSX with the exedy clutch, and while it was good on the track, it was horrible around town. He actually swapped it out for an OEM clutch and took quiet a loss in $$$ shortly after NSXPO 2002. It is basically and on/off switch with lots of effort. Not my favorite - actually, probably the worst clutch for street driving I have ever used.
 
I would highly recommend the RPS clutch. The pressure plate and clutch disc is the same German made Sachs unit as Comptech, however, the flywheel is a much better design. After 40k miles, the Powergrip 2 clutch in my car had a warped flywheel surface. Although the pressure plate side of the liner on the clutch disc was ok, the flywheel side showed significant wear. The warped steel ring on the flywheel acts as a cheese grater when it is no longer true. There are some animations on our website showing this patented design of the RPS clutch. Price is several hundred less as well. This clutch includes both bearings and is compatible with the 6-speed cars with the early flywheel bolts (same as Comptech).

Please let me know if you have any questions.

I am very happy with the single disk Exedy. It takes a bit of finesse for around town driving, but really no worse than the PG2 I had before, just different. The PG2 is like a leg press, gets pretty old in traffic, the Exedy has a VERY small slip window which can also get old, but the pedal feel is just a bit heavier than stock so I liked the trade off. My PG2 came apart after 25K which seems pretty common. Both clutches are great on the track and have enough holding power for the CTSC, the Exedy is heavier (28.5 lb.) than the PG2 (26 lb.) as a complete clutch, I weighted them, so those are real weights, not claimed. The Exedy has a lightened, one piece steel flywheel which should be pretty bomb proof, plus they are cheap!
 
I would recommend the Clutch Masters single disc. I have one and Brad Able from Autologic Inc. (Houston TX) has one. The clutch in Brad's car showed almost no wear after 18 months. It is a very streetable clutch and the pedal feel is not that much stronger than stock. I have had no problems with mine. I wanted a single disc for the fact that they last longer and I could switch over to a 6 sp tranny if I wanted to. This clutch is perfect quality and clutch masters has been proven. Clutchmasters did this project on there own to develop a single disc clutch. You can contact Brad Able for any detailed questions. 713-516-2081
