This is my stock clutch, which cooked after 4500 miles. Never been to the drag strip with it, only autocross.





The disk has lots of meat left on it, its just glazed to hell and gone...

 

will warranty cover ur clutch if it has lots of metal left and it is glazed?

 

What are you planning to replace it with?

 

No clue if warranty would of replaced it, but I really don't need another stock weak clutch to fry. So I put in an Exedy Hyper Single disk, and its working well so far.

 

where did u find it?

 

Z-1 Performance. Good people there, they got one overnighted to me for less than the price on their website.

 

if u replace it witha aftermarket clutch, will it void tranny warranty?

 

No clue. I autocross with the local Mitsu service manager, so I am not too worried about warranty issues.

Likely if your dealer is an *** they could make a case that a performance clutch puts more stress on the drivetrain.

You haven't been to the dragstrip, but have you done quite a few 4k plus rpm launches with it ? Or is this from just normal use ?

 

Yep, I have done lots of hard launches, never dumping the clutch but quickly rolling off it. Every autocross run ='s a hard launch. So my wear isn't typical, but even a stock clutch should not have failed so quickly. Most won't have this problem within 5K miles, but from the looks of things a whole lot of Evo owners will be seeking new clutches by the 10K point.

 

yea thats the problem, hard install, plus a good clutch for us is $1000-1500... is the single disc better for the street than the twin disc?

There is no way i'm spending 1000$ within 6 mos of owning the car to replace a clutch. I assumed that after 7 versions of this thing they would have made it bullet proof by now.

 

I am not surprised by the clutch wear. Because of the grip of the tires and the awd, it puts a lot of stress on the driveline (aka driveline shunt). No matter how smoothly you think you leave the line, it is a shock when the reciprocating parts engage. By putting additional stress (ie hard launches) on the system, then you risk wearing things prematurely.

As far as the car being bulletproof, I would only be surprised if I threw a rod or something running stock boost. Wearing out a clutch because I thrash is a different story.

When I had my S2000, people used to complain about that car's clutch, too. I drove every day in stop-go L.A. traffic and had 60,000 miles on the stock clutch when I traded it in. Just a matter of being mechanically sympathetic.
