an exedy tripple carbon.
clutch is totally gay for street use, but it was very stock-like to drive
look at what is says on page 2

and to rebuild it is rediculous, for another 18k

hey nice detailed write up ...
i just baught quarter master twin for my evo last week...
the reason i baught this clutch is that i dun drive my car daily ....and ive been having misshifting problems since last 6 months due to bad clutch so my 1st prioroty was to get the clutch which shifts perfect ....
i hope i made the rite decision and wil fix my mis shifting problem after installing quarter master this week ...

The original clutch being discussed was the SPEC Mini Twin. For all practical purposes it is the exactly the same as the QuarterMaster twin disc. I ran the Mini Twin clutch for 12K miles before it started slipping. It was noisey as hell and had light switch engagement. It was not my favorite
However, it is a race clutch that IMHO is not for someone who spends alot of time on the street vs. track. On the road course it was a phenomenal clutch. Shifting was incredibly quick and the low inertia made heel toeing a breeze. I didn't like it for drag racing, even though I could shift the snot out of it, because modulation/engagement was poor and I could never get a decent 60'. I would either slip it to long or roast the tires. Many, many, many, others have used this style of clutch ie. Tilton, SPEC, QuarterMaster and been able to use it effectively at the strip, but I was never that guy.
In regards to the Super Twin that is now being discussed, I think it is a much better alternative for more street/less track people like myself . It is much heavier than the Mini Twin which means shifting is slower, but the mass quiets down all the rattlely/ clankity sounds and improve driveability tenfold. I was more than glad to trade outright shift speed for everyday liveability and function. It has not seen the roadcourse yet , but it has been to the strip a few times now and modulation is much improved. My 60's are much more consistet as well. It's up to me to get better now that I can't blame the clutch anymore
.The larger disc area also provides retarded amounts of holding power over the Mini Twin as well. Who the hell is gonna need 1000lb/ft capability in an Evo?
The only issue I still have is a screech or honking noise when leaving from a stop. It is not present in Ted's car at all. When I asked SPEC about it the stated that Carbon content of the friction material can vary slightly and this may be the culprit. It is annoying when it happens, but this clutch is soooooo much better for my intended use(more street/less track) over what I had previously that Im very pleased overall.
