05 MR clutch problems...?
is it worse when it's cold? worse in reverse? worse in the lower gears compared to the upper gears? If so, it's clutch chatter, and fairly normal. If these are your symptoms, there is nothing really wrong, you'll just need to rev a bit higher and drive around it. An engine torque dampner might help also.
I don't think the disc will get glazed over from one moderate launch. My sisters WRX has the same exact problem and every 2 months it chatters again.. It is due to her driving style, too much easy engagement over and over again.. It was so bad that her whole car would shake sometimes..I just do one launch and problem completely solved. I have used this method for many stock and aftermarket clutches over the years and it works, as long as you do it in moderation. Luckily I have had zero problems with my clutch so I've never had to do this on my car and I have over 100 drag passes on it.. As far as glazing the flywheel over, that sounds unlikely because the organic material really never just transfers onto the FW and stays there, if anything, in the worst case you would have hot spots.Where the glazing occors is the disc, its porous material gets clogged causing an unstable friction characteristic as compared to a nice clean disc surface, kind of like when you move a plastic chair back on a linoleoum floor..

ill be the echo... it happens. first drive of the day, when its cold, if you dont rev up enough, if you dont let the clutch out correctly. im no mechanic but i dont think its a big issue.
If the symptom happens mostly when things are still cold, removing the restrictor might be the right idea.
If the fluid moves slower because it is cold, and the restrictor's job is to slow down the engagement of the clutch, it would follow that once the fluid warmed up, the symptom would go away. It could still happen after things warmed up because of the restrictor, maybe just not as easily.
My other car has only had the clutch replaced once in 180K. It's a 4 wheel drive and I showed it NO mercy (Drove it like the TV commercials)
My Evo's stock only lasted to aprx 27K, and I babied it.
Removing the "pill" is pretty easy. I regretted not doing much earlier. I didn't do it till, I think, around 20K. Should have done it the first week I had the car.
Good Luck

that I'm not the only one. Still sucks nonetheless, b/c I
baby the damn thing....the WHOLE car shakes when it
happens!
But yeah, it's mainly when it's cold;it does it only in
1st gear, and does not happen when goin into
reverse at all.

MR clutch chatter
This is usually a combination problem between the pressure plate surface and the clutch disc. You might try driving for a day or two intentionally down shifting (gently) every time you need to decellerate to reverse the engagement torque loads and if you are lucky refresh the surfaces of the clutch disc and pressure plate. If this does not remove the chatter you are probably looking at a clutch job and flywheel resurfacing. Unresolved chattering usually gets worse as the chatter patterns are built up on the pressure plate, clutch disc and flywheel. If you need to replace the clutch strickly follow the breakin recommendations which usually means no hard starts for 500 miles or more. Lastly, do not ever "hill hold" with the clutch. You are just begging for problems and short clutch life when you do this.
