HKS Twin Plate Clutch Slipping

Have a HKS twin/ dual plate clutch in my supra and its slipping (as soon as she starts coming on boost). The pedal has no play in it at all and is very stiff.

Is there adjustment on these clutches and if so can someone point me towards some instructions?

Thanks!

Cmon guys someone must know?

My search skills are lacking at present-day I can't find any info anywhere

Ever thought the discs need replacing?

Maybe best to order a rebuild kit from hks?

Yeah the discs prolly do need replacing because its done a whopping 3000kms since it was fitted...

From what i understand there should be nothing wrong with the discs because they were in EXTREMELY good condition when the clutch was fitted and the car hasnt been driven hard at all..and its only done 3k kms

Although the clutch was second hand it was fairly new (previous owner hated how harsh it was)..

I have read somewhere that the HKS clutches can be adjusted but i cannot find any more information.

Can anyone tell me if they have adjustment?

They can't be adjusted and they are a total POS. I think you'll find it's *uggered.

probably the most non-technical explanation you have given - still accurate though

And here I was thinkin' 'geez I hope that troll Chris Wilson wanders past here and throws his 2c in (which at current market rates is usually somewhere between worth a shit load and priceless).

No but seriously thanks Chris I was hoping you would happen past.

I don't suppose you may throw another opinion to this thread- are the exedy twin plates any good? if not I am torn between the 'RPS Carbon-Carbon Twin Disc Clutch which will work out the same as I can get OS Giken Triple Plate Clutch- OS Giken R3C type clutch.

Would you reccomend either of these?

I like all Giken stuff, and their clutches are first rate. Like all cerrametallic multi plates they do not like lots of slipping. I fitted a customer supplied RPS carbon clutch to his MKIV a while back, and it seemed finem but he wrote the car off before it had done many miles I am not a fan of aluminium flywheels with bolted on wear faces, as they tend to warp or come loose, but it's hard to say what the long term durability of the RPS would have been like. I am sure others here use them. I have triple plate Giken in my RWD Skyline, and I should really have used a twin plate as engagement, whilst not grabby, is too sudden to modulate the car properly in the wet. Do you NEED the torque capabilities of a triple plate?
