Default Slippy Clutch

A couple months ago I practiced launching for the first time. I thought I was releasing the clutch pretty quick but I guess not because now the clutch slips at every redline shift. If I granny shift its fine but I can't race anymore. Which part of the clutch is to blame for this? Friction disc or pressure plate? I can't afford an aftermarket clutch kit right now so I'm trying to isolate the problem.

Thanks

Probably the friction disk but when you go through the time and expense of pulling a clutch you normally replace all components. I have sanded both a FW and PP and just installed a FD, but only when there were relatively low miles on them.

not cheap at all.

It is a good 8 hours of labor, maybe more. You're looking at over a grand when all is said and done.

How much do the clutches cost? I was quoted $390 for labor on my car (although I do not currently need a clutch). Do clutches really cost around $600?

IIGQ4U, the damage to your clutch has already been done. My car is actually sitting at the shop right this moment waiting for the clutch to come in so that it can be installed. Labor is horrendous to get the clutch out of the s2000. There isn't alot of space under there for anything. The problem is that once the friction disk or pressure plate gets warped there is no way that the clutch will not slip anymore. The slippage will cause hot spots on the pressure plate which will be worn smooth. Think brake discs and you will understand how it works. The friction disk will expand and contract and warp due to this temperature difference. My suggestion is to drive the car normally no more redline shifting. If i were you, i wouldn't even shift higher than 6k rpms. Clutches for the s2000 are very expensive, just because the car is an s2000. Even if you go stock clutch and components you are looking at about 1k after everything is said and done. Drive carefully until you can afford to change the clutch. You should be fine.

s2krazy01 is the original poster. I was asking a question about S2K clutch costs in general. I contacted my mechanic to get a labor quote just for my own information. My clutch works fine and has 0 slippage unless I try to perform a hard launch and come off of the clutch too slowly.

The 'book' rate on an S2000 clutch is 8 hours labor so you will find it costs from $200 to $600 in labor. Parts will run $600 to $900, so with shop supplies and tax it is easy to spend anywhere from $400 for a cheap FD only replacement to over $1500 at a dealer charging to dollar.

I have done them in my garage and it has taken me the better part of two days with hand tools but I could probably get it done in a day now that I have air tools and some experience.

Just had mine done. Ordered the parts myself for around $400 I think. Had it installed by Honda, 8 hours of work @ $70/hour = $560. Flywheel was sent to a local machine shop for resurfacing ($50-$75 I think). The total labor cost was $712 with tax. The total with parts was right under $1100 I think.

Clutch feels pretty good, 130 miles into the break in so far. Does anyone know if the clutch will start to grab better as you break it in? I would think so since so since one of the reasons for the break in is to make sure all the surfaces that come into contact are mated together properly.
