Just installed RPS carbon/carbon and everything is great besides 1 thing that It rattles (sound of metal part hitting) during deceleration in gear at highway speeds and not during heavy deceleration.

Example going 50+ miles on the freeway in gear and leting the gas off it starts rattling really noisy.

Anyone has anyideas as why that migh be????

is it something loose...or just the harmonics of those large clutch components with a relativly light load on them?

Doesn't sound like the clutch. Did you do the install? Make sure all the motor mounts are tightened up reall tight.

I heard this kind of noise from my friend's EVO with a cerametallic disc.
That sound really disturb me.

Weird because the carbon discs shouldn't make this noise.

Personally. I think it is normal.

I commonly refer to it as "decel noise"... I've heard it in everything from a OEM clutch, to an Exedy Twin Metallic, to an ATS... Im sure other clutches make similar noises as well.

I personally wouldn't worry... buuuut, who knows Ive seen stranger.

yeah, it feels like 2 pieces of metal hiting eachother. and it only does it when there is slight downhil. it wont do it on the straight road or when the hill is steeper. ???

I had the clutch installed at the dealer, same guy does all the clutches on all their cars. Also they rebuld my 3,4,5 and Reverse Syncros (Mitsu 2003 TSB)

The noise you are hearing is normal. It will become a bit less after a few thousand miles and there is a layer off carbon dust built up, but it will never go away.

Usually RPS takes pretty good care of their customers so give them a call first. If that doesn't work, try our inexpensive 6 pad race clutch had been good for a year running 9's in Jeff Hill's car.

Yaroslav, Did you have the noise in yours like I was describing above?

I havent hear from anyone that RPS carbon carbon makes any extra noises

I think it's normal as well with carbon clutch to be loud, especially the twin clutch.

I've heard few twin disc that rattles on decel as well as when in reverse idle or just normal idle.

i have the same symptoms (decel noise) with my ACT Street/ProStreet combo. I didnt have any with my stock setup. so, i figured it was due to the lighter mass of the flywheel or the slightly beefier clutch...and was hoping it was nothing to worry about, but (like many) i still am worried that my car is slowly destroying itself.

anyway, am i correct to assume this, or might there be something amiss with my drivetrain? i just find it odd that the noises started as soon as i swapped the combo.

act shouldn't rattle...

but there are a decel noise that comes from the tranny, gears making those noise, not the clutch.

sounds like gear grinding sound.

i am sure that the noise not suppose to be there, it sounds like something metal is loose, plus the clutch is $3000 so i would think it should be rattleless.
