New Clutch Installed... (Exedy Cerametallic) - Honda Prelude Forum

Padge · 07-03-2004, 09:39 AM

I have my exedy cerametallic thin disc in now, and I have to say that it is much different then stock. The clutch pedal feels the same, but engaging it results in a hell of a lot of bouncing. I dont know if it is going to be like this the entire time I have it or just for the break in.

Some other guy on this forum said that this clutch is only for full out drag cars, not daily driven cars... and this is the reason why the clutch "bounces" so much. He says the clutch is only meant to be full engaged or totally disengaged.

Did I go overkill

Does anyone else have this clutch?

Is it bouncing because your still driving it like your stock one? Are you trying to slip it and stay smooth?

I just got done with my breakin on my ACT XTSS and it was bouncy the first time i took it out since my first reaction was to slip it like my stock one, but i soon learned to not slip it, either engage it or disengage, no in between. I don't have much experience with the Exedy's...but i'm sure NXlude will chime in!

what do you mean by slipping it? I find that I have to get those RPMs up pretty hi before I let the clutch out, otherwise there isnt enough power to make it not bounce, with my stock clutch I could leave in half in half out and have no problem with bouncing at all. Is this what you mean?

I just thought that I shouldnt be dumping the clutch at high rpms since it is new and I am breaking it in.

ok i have it too, its called clutch chatter. That is a stage 2 clutch which is fully streetable, you just have to learn that it doesnt feather out like a stock clutch. With practice and breakin you can get it down to near stocklike comfort. (i did) You willl need to take off at slightly higher rpms to get rid of some of that chatter......its really not that bad though.....

yep ive been driving it for over a week now (550mi) and I have learned to drive with it. No chatter with higher rpm drops and it doesnt slip at all. It only sucks in the parking lot

PS: Got my first kill with this clutch and the nitrous (finally no slipping) last night...

I have this clutch also, and I haven't noticed these problems. It doesn't really chatter on low-rpm starts, and it doesn't really grab too hard. I actually found it very easy to drive! And pedal feel is only slightly stiffer than stock, IMO. The only difference in this clutch i have seen is that when I downshift to a lower gear and it rev's the motor up higher (>3.5k), then it will make the car shudder......so i guess that's the disc chattering upon engagement.

And just a little FYI: the Cerametallic clutch does not have to be broken in! So romp on it already!

i got the XTSS.. n everytime i take off it chatter.. i dont lik riddin the clutch.. almost every time i start movin under 1000 rpm. so is chattering bad??

MNludeDVR · 07-14-2004, 07:42 PM

I also have the XTSS, i have absolutely NO chatter.....

JaXx4k · 07-14-2004, 08:07 PM

^^ but how high u rev. match? i hardly rev higher then 1000 to get it start movin.. i tap the gas but i dont keep it on the pedal.

MNludeDVR · 07-14-2004, 08:32 PM

neither do i....my old Sach's OEM spec clutch had more chatter than my XTSS does. I tap the gas to maybe 1500ish or so

why do you say that it diesnt need to be broken in?

I know that the ACT 4 puck and 6 puck clutches don't need breaking in like the street disks. Here is the quote from my ACT brochure:
"Break in period for a new ACT Race Disc can be accelerated by performing several hard slips in high gear prior to racing. Allow the clutch to cool for about 10 minutes between these slips to prevent overheating the clutch. The object is to lap the surfaces together under cad so the full surface makes contact."

That's what I read on Honda-Tech. It was something like the materials don't need a breakin due to the materials it is made from. They also said due to its materials, it can't really overheat, which I found interesting.
