I forgot to add, the actual height of it makes it a prick to put the box on if u dont lower the engine subframe

bullshit...ive done a few too....in and out in well under two hours just to check flywheel crank bolts.

that clutch is a little different to the one i have but height looks the same.

Merli wont buy one anyway...he's a bit of a brand whore... :P I bet he wears CK underwear.

i had this arguement with dan aswell.

like him, you can get f**ked too

ATS carbon twin = excellent clutch, only driven 2 but liked them and heard good reports.

OS twin = good for the money. and easy and cheap-ish to rebuild with genuine OS parts (no need to re-line second hand plates with new friction material etc). I've had a few and a triple plate as well.

Nismo twin = excellent clutch too. probably the best street/track compromise clutch.

ORC also make very good clutches. a little more exxy than OS but in my eyes just a bit nicer too. I've even used a blitz/ORC single which was awesome (made like a multi plate but with just one plate if you know what I mean)

I haven't tried the NPC but looking at the pics it's made the right way and has the right ingredients to be a very nice clutch. I would certainly consider one.

those extreme clutches are shithouse. I can't count the number of failures i've seen in everything from silvias, to GTI-R pulsars, to skylines. they are just shit. I wouldn't normally generalise about any brands product like that but I think i've had enough first hand experience of those failures to say so. and having driven on them they are not even nice to drive. shit shit shit shit shit.

be thankful it's f**ked now so you can move on to something nice.

for your car I'd probably just go the OS or ORC twin. or look at price of ATS carbon twin and the NPC twin too. if the NPC twin is less than an OS or ORC twin then seriously consider one. they look very good.

I will still stick with my origanal comment ATS for the win IMHO and as I stated once you use one you will never go back to a conventional clutch 1 of the GTR track cars i have built rego 26R32 has been running one of these clutches for 2 years now and has done a shite load of race klm's is making 500awhp and has never had a problem when the engine was last out of the car the clutch plates looked as if they had hardly worn at all by far the best clutch from my experiance expensive but worth every cent.

Not knowing ANYTHING about carbon clutches, I was a little worried about the durability of them in track/race only applications... But sounds like they're up-to the task!

Looks like there's too long a wait on the OS clutches anyway, so I'm waiting to hear back about availability of the ATS twin carbon and Nismo Coppermix twin.

:P

if you can wait till next week, an ats twin carbon will be up for sale. Darren and I will both be putting getrags in our cars. so it wont be needed.

Merli, Darren certainly knows his stuff and his recomendation would be enough to convince me ATS's are the shiz. Looks like you may be able to pick one up for a good price.

Thanks guys...

Daz has already PM'ed me about it... If I had known about this a few days ago, it would be a no-brainer, but I have already paid for another clutch, so I'll have to see....

Our clutch specialist checked the old clutch and says the 4 spring Extreme are a problem and the 6 spring ones they do are ok. Measured the clamp load to be 1220kg and can increase this and make 6 button, and would be fine, espcially with air cooling we do. I have single plate clutch 6 button in my car for many years and no problem. Heat kills clutches, and mostly sealed bell housing is bad enough for big hp road cars, but if going to the track they get very hot. Get some air in and out is the trick.

How are you getting air to the clutch?

<sigh>

Thanks for the heads up guys...

I've been through seven different twin plate clutches (and one triple) in my travels, some good, some bad, some excellent....

I thought I'd try something new, but after hearing the above reports, I'll stick with the tried and true OS Giken TS2CD. It'll be my THIRD one :P

At least it'll be a known quantity, but I miss out on trying new technology :ermm:

Mine was two or three meetings old and had done some dyno time as well.

It sheared the driving lugs off the two carbon clutch discs. Engine was making just shy of 500Kw. It let go coming out of the pits at wakefield park so I decided that clutch was not the best option for me.

I kept the whole thing but didn't even bother looking into warranty. Its still in the garage in a box.

What was the Torque Output ??? At the Engine ? , so where you running about 650hp ?

Those are some lovley vids (ads) that you have linked to there that are virtually void of any real tech info apart from how a clutch actually works wich I would assume most people in the motorsport section have a fair understanding of. Correct meif I am wrong but I was under the belief that the excedy carbon clutches are not actually a true (100%) carbon clutch. The actual friction material certainly does not look like it is 100% carbon they look like a woven blend of carbon and another material unlike the ATS clutch wich is 100% carbon. I have heard several bad reviews of the excedy carbon clutches but have not used one personally so cant comment from 1st hand experiance with their carbon clutches but going from my own experiance with some regular excedy cluthes theat have not been great and going from the experiance of others I dont think that I would take the chance with my hard earned money.

    • They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required. 
    • I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.
    • I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something? 
    • I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday.
