Exedy Twin Plate Clutch

[R33-RB26DETT]

Exedy Twin Plate

Says plate thickness is 2.75mm each. How can you tell how long its got left by this..?

I have searched for original plate thickness but couldn't find anything..

Any help appreciated. THanks.

contact an exedy dealer to find out what the minimum limit for thickness is.

Hi Guys,

Okay, found out that brand new they are 4.05mm each!

If they are 2.75mm each now, would they suit a rebuild OR could i just put them in as is?

Potentially how long could this clutch last for with this knowledge in hand? THanks.

no idea. you need to fine out what the actual thickness is of the friction material not the plate. you need to know the new thickness, and the replacement or minimum thickness.

even that knowledge still doesn't tell you if the intermediate plates are warped? or the diaphragm is shagged.

iv got one on my line. have had it now for 1.5 years been smashing it the entire time. prior owner in japan installed it so not sure how long it has left in it i would say about 20-30% more play. makes so much noise from the floating plate especially in low revs. but for drag racing and pounding the clutch it can take a beating for a long time. im getting rid of mine once it dies as the vibrating noise at low revs gets annoying after a while. lots of other options out there. i love the lightened flywheel that came with it though. revs up very quickly wants to sling shot off into the distance without even giving me warning.

From what you have said your clutch must not be fully engaging to be rattling around when your revs are low. If it is rattling abit when your idling at say a set of lights with your foot on the clutch that is normal but to be rattling when your foot is off the clutch and the clutch is engaged should mean something is wrong in my experience. I had an exedy twin plate and never rattled except when i pushed my foot on the clutch.

GTR-PWR. For that price i wold say your better off getting a brand new one. That way you know it will last a long time and everything about it will be new. Eliminates the chance of buying and finding out there is something wong with it like beer baron said. From memory they are only a few hundred more new but that was a couple of years ago.

yeh wouldnt say rattled when foot was off the clutch. but at low revs. it was very noisy. more like a heavy vibrating sound. i was actually not going to buy the car because i bit worried of the noise. but had a vehicle inspection and yeh was just the clutch. 1.5 years later still drives the same. highly recommended for heavy foot pounding though. great for drag racing.

No, not necessarily. My Supra's twin-plate (with lightened flywheel) is incredibly noisy at idle with my foot off the clutch (ie: with the car in neutral). In fact, it's a LOT noisier that way than when the pedal is fully depressed. I've had the car inspected and there's definitely nothing wrong with the clutch. Possibly it could be because you've only had a twin-plate with a sprung centre and anti-rattle clips, and maybe yours didn't have a lightened flywheel? That alone can be responsible for a lot of the noise. Mine is the HKS GD Clutch Pro which is the more racing oriented version, which means it doesn't have anti-rattle clips, it has an unsprung centre, and doesn't use the sequential plate engagement system that the Clutch Max uses. Under load, under 2000 rpm, it is INCREDIBLY loud. As in, maybe twice as loud as the car itself. So I think it's just down to the individual clutch/flywheel design?

I've ridden in a Skyline that had a more road oriented Exedy twin-plate with a sprung centre and lightened flywheel and it was considerably quieter than mine. I could only hear the rattle from inside the car (with the windows up) if the engine was at low revs under load, not at idle. It was incredibly easy to drive, too. Mine, however, is a bit of a bitch
