I think many of the failures (maybe not all of them) are due to drag racing. The Evo was never meant to deal with launch after launch of drivetrain abuse like so many typical idiot American drivers will subject their car to. Any powerful AWD manual transmission sports car will naturally eat the stock clutch after repeated abuse.

 

Your transfer case must hate you.

 

I think it likes it...

 

My 03 has 49k on the clock and i still have the FACTORY installed original stock clutch. This is wit roughly 350whp but i can tell the clutch is at the end of its life. I just today ordered an Exedy twin HD; thought i would treat myself to a nice new clutch since i got so many miles outta the stocker!


I am damn surprised that i got that many miles out of it, especially with the abuse i put it through (autox, drag, launches, highway onramps). I think it all depends on the driving style and VERY much on how you launch and how you release the clutch pedal.

 

isnt it the same exact clutch in the 14k lancer?

i think thats some bs.

 

I replaced the clutch on my 03 Evo after 19k, as far as my 06 evo 9 i have just shy of 27k and the thing holds strong, 03 evo was stock the whole time while i have been modded for about 400 whp on my 9 for about 15k!!!

 

just got my 2003 unmodified evo at 22k throw out bearing was makin a lil racket whey clutch was out. at 2738 miles started sliping now in the shop at 28089 miles clutch is bein replaced hunk of ****! should have keep my sti!! lol

 

Mine was good till 11000 miles.... then I dropped in a set of 280's and I could feel the clutch starting to slip at peak torque... actually, the data logs showed it too

So I replaced it before it really failed, but it was going to soon enough

 

i heard that the stock clutch from mitsu was only rated for a max of 250 lbs of torque and it makes more than that bone stock. an upgrade should be one of the first mods especially if anyone plans on adding power, which what evo owner isnt gonna add power

 

just blew mine at 15k miles, i think. My car does not accelerate after like 2k or 3 k rpms. so after reading everyones posts i think it is the clutch, SOB cant believe this, so early brand new car.

this is my first stick shift and i did grind, launch, missed gears all that bad stuff.

im gettin an ACT street clutch and is a flywheel necessary to add too? let me know thanks

 

hey LIQQUID, who installed ur clutch and how long and how much did it cost? i am lookin for someone to do it asap. thanks

 

yep it is^^^^^

 

hey LVIIIR, who replaced ur clutch? how long and how much? thanks

 

Almost 18,000 miles w/ over 30 launches and lots of ripping. Constant heel-toeing and high rev matching. My buddy Dustin has a little over 18,000 miles and probably over 100 launches and his clutch still holds and doesn't slip (and he has about 340whp). My clutch squeaks when I push it in when its cold out (i think my throwout bearing is a little messed up because I had the same problem with my Integra)...this might make the clutch go out a little faster but shouldn't make too much of a difference.

 

No, it is most def. NOT necessary... even ACTman will tell you that

You MUST have a fresh, flat surface to set the new clutch on, so if you are going to keep your stock flywheel as I did, you need to take it to a machine shop and have it ground... mine was covered in heat spots, they took .020" off and it cost me 30 bucks.

I kept the stock one as I like some weight on the flywheel, when you go to a lighter wheel, you loose some inertia, making the car harder to daily drive in my opinion. I went with a stage 2 Exedy clutch, so it was going to be harsh enough already without a lightweight flywheel adding to it.

For road racing, I know its a differant story... rev matching is easier, I've been told.
