Flyin Miata Happy Meal
#2
Im kind of the runt of mt.net, Ive had defective parts sent to me by every vendor here. I've had the worst luck from fm. My first happy meal was slipping on stock torque, the replacement kit had a defective throw out bearing, and the replacement bearing (now upgraded to the heavy duty variety) was also defective. They also sent me a clutch slave that rusted out in a few months without any salted road contact. I dont purchase anything from them anymore, but boy, do they have a good tech support staff.

im rocking my second level 1 FM clutch without issues. it has a nice engagement and holds my 300hp and 265tq just fine.
no complaints.
although either my pilot bearing or throughout bearing is not great, it makes a slight humming/spinning noise when in neutral and clutch is not depressed.
Both my FM clutches did this, its not bad, just a little annoying. and no way am i pulling the transmission just for this issue.

I have a 300hp FM clutch. Had it in my 91, never any issues(only for 2k miles). Swapped it into my MSM, but noticed one of the 4 PP Springs is loose in its cradle. FM said it should be fine. I really didn't want to put it in, but I also did't want to spend more money. Driveability was great, no shudder as I only have a 14lb flywheel. My Pilot bearing was ******* shot thought. In 2k miles? Yikes. Put an oem Pilot, and FM's new heavy duty TOB which looks **** compared to the ACT "heavy duty".

I have not replaced them yet, but plan on it shortly.

i bought new excedy master/slave cylinders on amazon for like $30 and will update if my shudder goes away once i change them out.

because my car does the same exact thing, i bleed the clutch and its all good for a while, and then it starts to shutter again. i am guessing air gets into the system from weak seals in either master or slave cylinders and air causes the shutter as it doesnt release the clutch as smooth as airless fluid does. that is my theory.

My clutch is only doing it when it's hot though. Could be when fluids expand from heat it would allow air in?
edit:
Reading m.net suggests a few things. Could be motor mounts. Mine are shot.

I'm on a FM1 clutch with a OEM flywheel. New master and slave. I get an almost imperceptible amount of shutter. No complaints from me. ~250wtq

I installed a used one (10# flywheel level 1) with an FMII with about 10k miles. I used new oe bearings, and replaced the master previously that was leaking down. I've put another 10k on it and have had no issues. Not sure how true this is, but the install manual says most issues are from incorrect linkage adjustment.

My car had cold start-off shudder when I bought it with 60K miles on it. I replaced the clutch with an FM happy meal with the 11#(?) flywheel in anticipation of boost. It shudders a little less when cold now. At the time I bought mine, FM was including OE bearings, which was good to see. Anyway, the clutch was not the cause of the shudder, and I need to look at various drivetrain mounts/bushings and/or hydraulics. I rather like the FM clutch and flywheel. The feel is very similar to my RX-8, which is quite good.

I've always liked the feel of the FM Level 2 clutch - progressive engagement and reasonable pedal effort. I'm on my second one (the first was changed because I had the transmission off for other reasons and bought another just in case it was close to being worn out - it wasn't). The second lasted 4 years and 32,000 km (<20K miles) before shifting became progressively more and more difficult. Here is what the back side of my clutch looked like:
Root cause is that the failing clutch was dragging during shifts, making them nigh-on impossible without matching revs. Needless to say I'm not impressed and my new clutch is the SuperMiata twin (with street flywheel).
