CMC let go. stock clutch , 31k . AMS cmc ordered . i wasnt expecting to upgrade until my clutch was shot. oh well, happy monday.

Pretty rare to see a 2010 failure, especially on the stock clutch. Are you sure that's your problem?

Yes sir

I think some early 2010 EVOs may be affected. I bought my 2010 in November 2009, and in June 2010 with little mileage and stock everything, the master died without warning- 1 corner from my home, that made it OK.

It happens.

my evo was built in june of 2010. mc let go about 3 miles from home. could have been worse for sure.

Why are the 2010's so special? I thought Mitsu never changed them?

Is this a frequent issue?

apparently. the oem clutch master cylinder is made of plastic. the kit i bought is basically an adapter to use the evo 9 aluminum cmc.

That is better, why would Mitsubishi be so cheap? Well their metal sucks we all know that! I would imagine the plastic used may swell letting the rubber cups inside push fluid around the bore? Who knows the real issue Ia m just trying to make sense of it.

Good job ordering a better one. Honestly when you get your old one off you should take it apart with pictures and measure a few things?


Good luck man!

i may, but i'll probably just slam it in the garbage

Hah! You really should look into it and do a write up (: or send it to me and I would!

I love knowing why things do, and do not work

More or less frequent, especially on cars with upgraded clutches.

I can't help but ask again--why are the 2010's so special? I thought Mitsu never changed their CMC designs?

72K on stock 2010 clutch and still running strong.

Each year they have become more reinforced. They're still made of plastic, but it's only the 2008's with somewhat high failure rates.

Interesting. Has anyone been able to do side-by-side's?
