IDK dude, a lot of those miles are highway too.
Everyone's testimony seems to contradict what your saying regarding the mileage, at least when it comes to the Exedy...
Truth is, it may not be the disc, and if that the case then its hard to blame the clutch. Maybe your trans is bad...?

Most of my parts will be here this weekend or early next week.
Rebuild kit, TOB, and AMS trans mount courtesy of Mark and Mike of EM2 Performance. These guys run a great shop.
Clutch fork stop, new clutch line (full line) courtesy of Emery from STM. Free shipping from STM FTW! Also picked up the STM uicp while I was at it. (Marc, I will bring yours to the next autox)
Also ordered new OEM fender liners and all the needed clips from Mitsparts.com (Cherry Hill Triplex)... $9.00 flat rate shipping ftw!

Marc, I was banking on experiences like yours, so I didn't think my clutch would ware that quick. I think Petey has like 50k on his, and he beats his car at the track all the time. I don't drag race, so I think its just my driving style for the most part and the heavy traffic I drive in all the time. I also started to launch at the autox. Whaever, I don't care for the ware. I just hope thats the case and not a bad tranny.
You also have to remember that I'm not making as much TQ as you are, that is a factor also. I also think your problem is more of a mechanical wear issue on other components, not the discs/clutch... a problem like you're having in my limited experience usually points something mechanical failing either in the trans or with the hydraulics.
A disadvantage to a twin disc is that since a twin disc clutch has 4 wear surfaces, a twin disc if it's slid a lot as in ordinary driving, experiences accelerated wear and a rapid drop off in clamp load from the pressure plate with subsequent slipping. This sensitivity to wear can make rebuilding a twin disc in a daily driver an annoyingly frequent occurrence. - Mike Kojima
The man is the biggest nerd so I just believe what he says.

I have a buddy who HATES his carbonetics clutch with a passion. Hes only making like 400wtq and its already slipping...

You guys know how I drive, I probably race more than anyone on here, but I like to think I'm easy on parts. I never ride the clutch, always rev match on downshifts and I know how to launch so it doesn't slip too much and overheat. If the clutch didn't work so well I wouldn't still be using it and I would be recommending it.
I don't agree with that statement. Here is why; two discs = twice the surface area to spread the wear around on. Thats the whole reason why they are prefered for a high HP application, because in order to hold all the TQ you need either A: more clamping force, b: more surface area on the discs, C: a more aggressive disc material, or D: a combination of all 3.
I know, I wasn't trying to sound harsh or anything, just giving you my unwanted opinion.
I kinda understand the engineering behind it (at least I think I do). The smaller discs are easier to spin compared to one larger ones due to less rotating mass. That should translate into faster shifts and quicker accel/decel... I remember all that crap from when I bought mines back in 05

I would be surprised if it was the disc, just doesn't seem like much use. I always thought the exedy would last longer than that, I've heard of the others not, tilton, spec...
You'll figure it out.

Doesn't matter, I still like it alot. Just becasue it's expensive doesn't mean it is supposed to last any longer. It has been a great clutch while it lasted. I would not mind getting another one at all...thats why I'm rebuilding it. I estimate around 15k on it, both daily driving and autox'ing, maybe more. Its about average for most people with these clutches. I drive my car more than any of you, and stop and go traffic does a number on any clutch.
If you think about it, a regular clutch and a lightened flywheel already cost about $1000.
BTW, I'm not rich!

Twin disc has more friction surface area so his point is moot.. On the other hand if you wear one disc more then the other, then yes it will wear quicker, but he wasn't even close to saying that.. What he was saying applies to single disc clutches in the same way...... boom
