Clutch Dying?

[Vladsta]

Hey kleinerbastler,
I'm stuck between getting the genuine replacement parts of going with the Exedy Heavy Duty...

If you could pick between the 2, having now go the HD, which would you go?
Is it so heavy that its a pain in the a$$?

Also,, where did you order it from?

Cheers,

@vladsta
The exedy hd with flywheel becomes litghter with the pedal with time, now it´s just a bit stronger than orginal, but the clutch closes at point - no slip.
The only thing against this exedy stuff is the noise from flywheel/clutch, but also this becomes less, now just in low revs you hear it. But with it, it is possbile to shift fascinating fast and smooth.
I bought it from horsepowerfreaks.com

Is there anyway to dampen that sound/ vibration through the lift off acceleration. Exedy hd clutch and lightweight fly is kinda loud : (

don;t buy exedy....?

My Sachs clutch is silent, smooth and a softer pedal than stock

Don't think its the Exedy clutch, more the SMF > DMF and the ORC lightweight flywheel rattling

[Robbks]

well, if we're talking clutches for 3.0 then there is no DMF to worry about.
but heaps of WRX guys with both 6 speeds and 5speeds (running SMF) whinging about the noises from Exedy clutches.
I drove a 6speed lib with exedy clutch when deciding what to go with for my car, and Exedy was immediately ruled out.
OEM clutch is too stiff on the pedal and teh Exedy (non-HD) was worse than that.

The noise is no clutch problem, it comes from the light flywheel. It depends on how the mass is shared, if low mass is in the outer region of the wheel, the noise is more present than if the mass is more in the outer region. The noise will decrease with time and km (~1000km), but if it new installed you are right, you think the car will broke.
Using the original flywheel with exedy clutch should cause no noise.
Some guys have good results with lighten the orignal flywheel, so you can influence the massallocation.

here is the clutch problem thread on rexnet.
worth a read

It's not the clutch being an Exedy that's the issue
it's Exedy making a cheaper version as an "OEM replacement" that's inferior to teh real thing.
Regardless, i was informed by my mechanic, box builder and the clutch builder that exedy have changed their "organic" friction material over the past few years and it's an inferior product to the earlier stuff.

and the pics.
the first one is the Exedy Aftermarket one that rattles
NOTE: 4x single, big springs


and below is the Exedy Built, Stock Subaru Clutch
NOTE: 4x Dual Springs, with subaru PN stamped on it

[kleinerbastler]

Yes, there are maybe differences in design, but there are no OEM stuff which hold 500Nm or more.
If you are looking after chattering or rattle of stronger clutches, so you will read that not only Exedy have this noises, also ACT and other aftermarket stuff (Carbonetic and so on). And if you use a lighter flywheel the risk of noise will increase.
But i have writen, that after 2000km the noise is gone, just a bit now in low rpm.
If you will use no SC or Turbo on your H6 are maybe OEM plate with stronger pressure plate enough.

I just had mine replaced with an exedy heavy duty clutch, no noise and it's great. I didn't do the flywheels, just machined it. I was going to go for a Jim berry but I was given reports about how it wasn't that much better. Doesn't really bother me because I'm running anything more than stock

[hamish_023]

Rob, just read that entire thread and my symptoms are exactly the same.

Anyway my story is that my clutch was in need of a replacement badly and couldn't wait for an order through PHAT. Took it to S&J Automotive and they suggested two options, OEM clutch and Exedy replacement. I asked in these exact words "Are there any down sides of the Exedy clutch" and the answer was no.

So agreed to have the clutch replaced and then asked if it was worth doing DMF>SMF and they said the prefacelift GT's already had SMF so didn't need too.

Phone call 4 hours later saying They fitted the SMF and exedy clutch and was going to cost $1800...

Hi I have a MY05 JDM 3.0R spec B. AT the moment I am hearing some weird noises when I depress the clutch and I also hear a loud shriek at the point of load when moving off. I was advised that it was clutch time .

Since I live reasonably close to the US I plan to get the clutch kit from there. But when I do searches I only see clutches for 5 MT and not 6MT.

Could a 5MT be used instead? If not could I use the clutch from a 6 speed WRX?

Should I go back with a stock one or should I get an after market one to deal with my heavy foot?

Thanks for any info you can provide.

do the 02+ USDM STi's have a 6speed box?
if so, a genuine STi item to suit that may be a good option for you.
higher clamping than the 3.0 unit, but OEM feel

I priced up a genuine STi clutch for my 3RB and it was about $800.
(given that exedy clutch part numbers for 3.0 6speed are the same for AUDM 02 STi WRX)

I did some checking and some of them do have 6 speed boxes. Unfortunately the sites that I know of that I would get the parts from only have for regular subs, not the sti models.
