hello, first of all i'm new to this forum, i have a customer who has this very well modified Evo V, we buy an ATS triple disc carbon clutch for it and it lasted just a few runs, at first it was hard to engage gears but last he ended broken the tranny's syncros (if a dog clutch gearbox has syncros), when we disassembled the clutch we can see the floating discs with warpage and a great blue color on them, the people at ATS said it can be a driving error because of sliping the clutch too much at the starting line, but we know that the car's owner (and driver) is an excellent driver, so there's something that produces that the clutch can't engage adecuatelly, anyone has any clue of what can be causing this?

 

what kind tranny fluid did you use ??? and how was the release bearing bad shape and was it new when you replaced the clutch trying to get a feel and see where your at thanks let me kno ill try to help you out

 

one more thing did you have the clutch adjusted ? the problem could of been that the clutch was preloaded while the clutch was all the in and it wasnt fully dis.

 

you clutch is slipping, in other words?

other wise check your shift linkage and adjust your master cylinder rod.

 

Clutch was slipped too much plain and simple. Carbon can withstand astronomical temps and not warp. Steel cannot. It sounds like the clutch never even got a beakin period. Carbon on steel clutches dont make sense to me. carbon on carbon is the future of clutches.

 

carbon carbon is already out with carbon carbon carbon being out as well.

or are you talking about carbon disc on carbon clutch.

 

instructions state you may need to adjust the clutch pedal after instal, did you do this? Also make sure the rod to the slave cylinder is adjusted correctly.

 

yes, I did that. you should too.

 

ats is the best clucth compare to ogura clucth but ogura more expensive than ats . especialy for carbon clucthit can slip . the problem please check the installtion cos mostly the ats change clucth from pull type to push type. I have already use for my evo until now and no problem

 

On the 8 you need to notch the release lever opening in the bell housing per ATS instructions. Not sure about yours but that could cause a lack of full engagement.

Thanks for the replies, no the clutch doesn't sleep nothing when in gear, at first when the clutch was recently installed it worked perfectly, but seems that the problem was no break in period, in fact the car was raced almost inmediatelly. All the pedal adjustments and the rod to the slave cylinder was adjusted too. We're gonna get the carbon plates instead of steel ones so it won't warp again. That's sad considering ATS triple carbon clutches aren't cheap.

 

Get the carbon coated metal option.

 

ah yeah the break in period is very important on the carbon clutch. Even before you race your suppose to warm it up.

 

Where in the instructions did it say this? I recently installed mine and had read about having to do that on these forums, but I didn't see anything about it in the instructions. Can anyone send me the instructions on this part?

 

Also, my clutch rattles really while decelerating in gear at around 3500 rpm. Anyone else's doing this?
