Current spec is ACT Comp Clutch with maybe 10.000 miles and OEM Flywheel; it slips terribly at anything above 3rd gear 5500. I had been told that there was a danger of crankwalk due to the clutch, TOB and fork design and that a carbon carbon set-up was recommended. Thinking of going with a Tilton 5,5 or 7,25 carbon carbon with lightweight flywheel option and their TOB set-up. Is this a good option or will it mess with my synchros/tranny? Also will this minimize crankwalk possibilities? Finally be aware I have a DriveShaft Shop driveshaft/Nissan Z rear end good for 1000HP - is there anything else I should be concerned with in the driveline? Is there a better set-up. Essentially looking for something we install and don't have to mess with anytime soon. Been following the 2nd gear woes but don't really drag race this thing street nor track

Skilled driver, licensed road racer and certified HPDE/Race instructor so shifting/footwork is at least adequate - no drag racing although I would like to use this sub 30.000 mile car for daily driving and occassional HPDEs.

434 Wheel Horsepower / 255 Wheel Torque - pretty mild by most standards here and frankly still too much for my usage

Goals are:

1. to have a clutch so strong would never have to worry about it even if doing skidpads all day with students or stuck in traffic or if I just wanted to beat the hell out of it.

2. had heard that the combination of the style TOB and fork combined with ACT HD Race clutch were jeopardizing the motor due to inducing crankwalk.

3. ACT clutch has NOT held up well - less than 10.000 miles and not abused.

4. experience has been that no clutch feels like a carbon carbon multidisc - albeit no experience in a S2000 application.

Educate me on pros and cons of each in your opinion and experience with S2000. Is carbonetics trustworthy and can I use the Tilton TOB with it???

comp clutchs are good, i ran their sprung 6 puck for a few years with no problems, although people are gonna say its hard to drive, which its not, i currently switched to the comp twin and love it, but thats way too much clutch for the power u have

I've ran Tilton carbons in 2 of my previous builds (7.25"). Best clutches I've ever ran, and the only ones that didn't need any servicing. Not to mention the benefit of an all carbon clutch setup. I was also told by numerous people that the this clutch would wear out fast if driven on the street, but that wasn't true at all. As a matter of fact it lasted longer than any of the other. Tilton even includes an extra "floater" that you can switch too when the discs wear to a certain thickness (measuring tool and info included with the clutch) but I never had to even do that.

I've also ran CC, Clutchmasters, and ACT clutches with success, but all 3 of them had any issue or two throughout their lives.

Passmans2kny: why will any other single plate hold any better than the ACT when it has given up the ghost at less than 10k without being abused? Supposedly this is a robust clutch that has crankwalk as its only downside. Not flaming, asking for explanation. Suspect a lighter flywheel will actually help the situation though. What are the downsides to going to a smaller inertia clutch such as a small diameter double versus a big single with such low hp car?

Bosstedf22c: did you also do the tilton flywheel? What was your experience with the Tilton TOB set-up?

Anybody experienced with Carbonetics carbon carbon /flywheel set-up - yeah nay and why?? Can the Tilton TOB be used with this?

i dont have any experience with act on s2000s, so i cant comment on that, but a lot of people run them with no issues, also i heard act changed the design a few years ago bc of the crank walk issue

Actually just got off the phone with Carbonetics and am pretty impressed. Their design is pretty unique and for a track as opposed to drag oriented car, very sensical. Their price points are about half a tilton and I like that the use a design that is easy on tranny and motor shockwise. Essentially they provide a lot of holding power but by being a little heavier as a package fill the void nicely between the toggle switch Tilton set-ups and OEM. Any feedback I should know? Oh yeah and it is compatable with the Tilton TOB
