Organic vs Button clutch

I'm looking at clutches at the moment, and my dilemma is this:
I'll be seeing a minimum of 230 rwkw, quite possibly more. Obviously a button clutch would be the best way to go, however I do approx 1000 kms/week, with a lot of that in traffic. With even the mildest button clutch that will still be moderately unpleasant. Will an organic clutch take that sort of power RELIABLY? If so, is there any particular composition I should go for?
I'm told Western Clutches in St Mary's are the go. Can anyone back this up, and/or recommend other places?

Perhaps go for a heavier pressure plate and maybe mod the hydraulic system to provide more lever force for the same pedal force.

Go a ceramic plate, or brass button clutch. 5 Puck.
They're not hard to drive in traffic once you've gotten used to it. And YES you can feather a brass button clutch. Just people who try and do it first time they drive one can't.
I can take off normally in a 5 puck brass button clutch (No huge revs needed etc etc) just nicely take off fairly smooth.
Just learn to drive it. I also couldn't tell too huge of a difference between my standard clutch in my nissan Navara and the 5 puck in the other car I was driving (Regarding force to press it in)

although i havent purchased from jim berry ive got a number of mates that have and have been most happy with his advice and service.
im currently running a 4 puck ceramic in the aw11 and its fine.. was a bit horrid for the first few weeks in traffic but once it bedded in it was tops. and still is. works a treat and isnt too tiresome in traffic. if i had the option again i probaly would have gone witha 5/6 paddle clutch just so its a little softer on the take up but i have no issues with it as it currently is nor does my gf.

I drove my GSR with a 4 puck BB sprung centre for a while, it was a great clutch, never slipped, and was 'reasonably' compliant in traffic, but as 'friendly' as a BB can be,i still wouldn't recomend one for someone who drives in serious traffic daily, you won't get the same performance out of a full plate clutch as you would out of a BB, but its also going to be gentler on the driveline..
there are also sprung puck clutches that run different friction material (ceramics or kevlar etc) and have like 10 or so pucks around the friction plate..
seriously though, if you are 'only' looking at around 230rwkw, you should be able to get away with a serious organic or simular... as long as you know it wont stand up to heaps of runs at the drags on a tracion prepped surface (it won't have a problem with a few) however you wouldn't want to run slicks

Well 230rwkw is probably where the power will start at. I'm not sure what to expect after a tune. Hoping for 240... possibly even 250rwkw.

What you could do is, take that lovely and much sought after manual setup for the 2JZ and sell it. Then put in an auto for your commuting needs. A well setup auto will be a nice thing in it anyway.
Besides it's only a supra so it's not like you'll be messing up the handling with an auto

ive got a 3 puk ceramic button and its simple to drive with every day i regularly commute to and from work and out to windsor on the weekend and have never had a problem with it.. The clutch is a bit heavy but so was the dakin h/d i had in there b4 hand anyways..
The only issue ive heard with brass button clutches and driving them in traffic is that they tend wear out quicker than organic type clutches this is only what ive heard tho..

or just get an organic twin-plate...
although it's twice the cost of a serious other clutch, you also get twice the clamping force for the same pedal force (since you are doubling the area being pressed against by the pressure plate)
new they are around what? $1000-1200? and that includes the flywheel required?
|
The ringing sound of a twin plate can be quite annoying in traffic though. In fact I get really embarrased when I pull up at the tolls and people look at me like my car is falling apart just because of the twin plate.
I'm pretty sure they are a LOT more than twice the price of a good single plate as well.
I'd be interested to check out the drivability of an organic twin plate. Mine isn't the best but it is an unsprung ceramic setup rated for 700ps.

Speak to Justen, as he has some good experiences.
Extreme clutch here in SA (and on the web) supplied mine, and I got a 5 button sprung centre jobbie, and this should be fine.
It is only the solid centre ones that get really grabby. Norbs shoild have some good hints as well.

Yeah, I have a 5-puck ceramic clutch with a sprung centre. Once you're used to it you can drive it quite comfortably in traffic, which I do regularly. I wouldn't trust an organic clutch to reliably hold that sort of power long term. Keep in mind I've had mine for over 2 years and it's still going strong, not a hint of slip ever!

the one we have in the 4age aw11 is a four puck exeedy sprung centre.. it is pretty easy to drive in traffic and as said above id trust it with that much hp in front of it more then i would a organic.
once you are used to it its pretty polite to drive in traffic you just have to be careful.
my mates levin has what feels like a 6-8puck ceramic sprung centre.. not really sure casue wehavent taken it out and it feels very polite around. infact next clutch for the other mr2 will probaly be something simialr. a hit less agressive then the 4 puck but much much grippier then the organic i currently have in the gze mr2.
