Twin Plate Clutches

[Uncle Arthur]

In particualar the plates themselves. Have heard that facing materials such as carbon and kevlar give a smoother and more progressive uptake, better than the metallic materials usually used. Also what type of plate eg button types are a bit in/out from what I've heard.

Got to drive the car in traffic, need a twin plate to keep pedal pressure under control given the potential power involved. So whats the go?

[R_ZEE]

I have a an exedy twin plate in a jza80 supra and its an absolute bitch in day to day driving,they are not meant to be slipped,either off or on.

I had a conversation with the exedy reps at w.s.i.d last saturday night.The carbon plates are only really designed for racing because they can withstand alot more heat but the downside is they need heat to start working properly otherwise you will have clutch shudder and they will slip when cold.

What sort of power are you making or planning on making because the twin plate was only recommended after 450rwhp

[Bob Saget]

You'd be better off getting a custom twin plater done, by someone like direct clutch in brisbane. Tell them you need the clutch to be easy to use in traffic but take xxx amount of Hp and they will come up with something.

An R ZEE says off the shelf twin plates are more racing orientated

and i had a conversation with the Exedy rep at WSID last Friday night, regarding the Hyper Single.

Basically, Exedy are shit other then standard type OEM clutches.

Plenty of other options.

Jim berry (QLD) for starters or western clutch in Sydney

Yeh I know about DCS and Jim Berry, just wanted personal experiences. Don't some cars have twin plates stock? How do they go?

[Morgs]

The F6 Typoon is supposed to have one, apparently a few failures during Motor mag testing etc.

I had one for a while in the GTR (then pulled it out for a tripple plate), sprung NISMO twin plate, didn't rattle, held up to punishment and as easy to drive as the stock clutch.

GTR are deceiving though, they have a vacuum booster on the clutch master, no?

[IMOA]

We use Exedy twin plates in the drift car and the GTR. Drift car gets the utter bollocks belted out of it and the clutch is standing up brilliantly while being happliy driveable in sydney traffic. In the GTR it's gets semi regular redline dumps which it's handled fine and it's often driven to work in sydney peakhour by a chick in high heels. Easily the best clutch I've ever used

[Uncle Arthur]

The linked Tilton FAQ on plate materials is interesting, seems like this is a crucial choice http://www.tiltonracing.com/content.php?page=faq&view=2#qid4

that was only due to a very selective (to the inline 6 only) harmic vibration issue, and has since been fixed. It had nothing to do with too much power etc

[Uncle Arthur]

Any experiences with various plate materials?

[EfiOz]

The Typhoon had big clutch probs during development. That model would have been released months earlier except for that issue.
