'boss' Drive On A Twin Plate Clutch

[LotusGTR]

My goal is to find a twin plate clutch that as much as possible will be tractable and quiet and at the same time hold 350RWKW (which I don't have but I might one day and can't be stuffed doing the whole clutch thing twice. I've got 300).

In my searches I've found a Nismo Coppermax and Exedy 'something or other' twin.

I've come a cross the term 'boss drive' and would like to know what this is and what it means in terms of how the clutch will perform. Also, I understand clutches with sprung centres reduce vibration and chatter?

Any suggestions in terms of me finding a clutch that meets the above criteria will be gratefully received.

Cheers.

I would definately get one with a spring centre, far more streetable than a solid centre

[LotusGTR]

Thanks. So boss drive = solid centre?

So, does this have a sprung centre? Sure looks like a series of small springs in the middle jigga?

my ats carbon twin plate is very tractable. Its only a little rattle from around 2-2.5k other then that is great.

yes that is a sprung centre

Any decent twin plate will hold 350rwkw

Yeah but the 'wrong' one will be a bag of shite to live with.

My HKS Tripple has a solid center and i am not looking forward to that.. wish i went the sprung center now.

Nismo Twin super coppermix in mine..smooth as a babys bum...Had ATS carbon in before but that only lasted 1500k's before frying.

The Nismo twin feels like standard

Why only 1500kms? What makes you think the Nismo item will last any longer?

[elrodeo666]

The Nismo has already lasted longer...I dont know why the ATS fried as was rated to 600PS and car wasnt making anything neaar that at the time. I live in Hokkaido(Japan) and it gets real cold here in winter(-10 to -20c) and all I can think of is the carbon doesnt like the cold.. It was put in by reputable jap tuner and they couldnt figure out why..

The Nismo is way smoother to drive though..

Looks like the Nismo item is the way to go. I still don't know what boss drive is. Perhaps it's academic as I now have a clutch of choice.
