i'm running an ACT, but i dont know if thats gonna hold up next year, as i felt a little slip coming out of hairpins this year

i would have to say a twin disk is going to be your best bet, the brand will be up to you, but w/ the twin disk comes the risk of breaking drivetrain stuff

I run the exedy twin plate which I have had in for 20,000 miles now, and it holds well. (putting 420whp to it)

It is excellent. I will highly recommend this clutch. It is what has been used on all the Showcase Mitsu autocross cars and my own personal cars. On my silver EVO it lasted for 40K miles and about 2 seasons worth of autocross and drag racing while making plenty of torque. . .

If you can afford it this would be my #1 choice.

BTW, it comes with a lightweight chromoly flywheel. I think everyone with the Exedy Twin uses the flywheel that comes with it. . .

There are so many people selling them. If you are going to do the install, just check around on the vendor for sale section and get the best deal you can.

If you are having a shop install it, think about purchasing it from that shop if they are a dealer. Even though you may spend a couple hundred more, if something goes wrong with it they will have more of a reason to stand behind their work . . .

I, too, use and recommend the Exedy Twin HD (get HD, not SD) cerametallic. Daddio and I talked about it at Nats and both really like it. It appears Evolutionary concurs. I have used the ACT HDSS, Exedy 4-puck cerametallic, Exedy Twin Carbon, and now the Twin HD (had it at Nats), and it's a great clutch for both racing and DD. It actually has the lightest pedal feel of any of the above clutches - only stiffer than stock but not by much, although it's been years since I had a stock clutch. The Twin Carbon was superior and drove like freakin melted butter at all times, but it would slip when not heated up, which meant I could never get on the gas when on the highway without slippage, so it was annoying. It was really only for race cars, but man was it smooth. The cerametallic is not quite as smooth, but it never slips, doesn't have to "heat up," and is not annoyingly grabby like the 4-puck.

Hmmm. . . I've had a dissimilar experience with the HD. I've found it to be too grabby and hard to drive around town. Like a light switch - either on or off with no slip. Also has a fairly heavy pedal pressure. .

I recommend the Exedy Twin with the SD pressure plate. Saves a hundred $$ and is much easier to drive and will hold up to 400whp all day long. . .

The SD is typically frowned upon on the Evo due to not performing or holding up well, but who knows, maybe they didn't put on the HD cover before sending it to me, because it's not anywhere near as grabby as the 4-puck and has a very light pedal.

I am going on my second ACT clutch with flidezza (sp) flywheel. I got 70k miles out of the first one and about 3 seasons of autocross with a co-driver for 2 years.

the only reason I replaced the clutch was because it was easy to do while the engine was getting rebuilt.

I disagree with this. In fact, I believe the opposite is absolutely true. Let's not forget that for years ONLY the SD was available. The HD just came out around the beginning of '06 if I remember correctly. There have been a few who have had issues with the SD, but that is true with every clutch out there, including the ACT which is arguably the most popular aftermarket clutch for the EVO.

Sorry, after typing all that I just want to clarify that by SD I am referring to the Standard Duty Twin Disc, NOT the Single Disc. I can see where the confusion may have come. HD is the Heavy Duty Twin Disc. . .

well as some of you may know, i am going to be using an 18x10.5 in front w/ 18x9.5 in the back next year. anyways, i found some enkei rpf1's that look real nice that i really like. they come in the 5x114 and in the 18x10.5 but the offset is +15... do you think i could get that under stock fenders? we test fitted some nt03+m's in a 10.5 and they fit fine
