You forgot: add squats and calf raises as part of your routine. Then no clutch will be too heavy. Bonus, your legs will get firmer and more toned!

I never thought the FM2 was that heavy. the FM1 felt like stock if not softer.

This is what I was hoping!! thanks! I have also heard of a few others whose FM disk shattered. Idk the back story though.

Was there a defective batch of FM2's or something? I remember reading something about spring issues a while ago.

They had to be paired up in cars with ST valve guides.... Otherwise, good to go.

My mom (at the time 54 years old and 4'11", maybe 120lbs) was able to handle FMII. That should be a good point of reference.

Drivability on an FM2 far outweighed the chatter of a stage 4 pucked competition clutch or the tiny amount of added pedal effort.

It'll also holds enough torque for many.

I called up 949 yesterday and talked to them about their super miata clutch (with ceramic 4 puck which they're currently out of stock on) :( :( :( :(

but he told me one of the goals in making their pp was for it to be easier to push than the FM2, roughly 25-30% easier. it's claimed to hold 340ft/lb which would be perfect for me.
does anyone have this clutch? how does it feel?

They won't have them in stock for roughly a month and I've got a big track event early June. ugh.

Not sure why you're skipping leg day when you have options available now. IMO, with a lighter pedal engagement and high tq capacity of a 4 puck, I think you're going to be forced to be skilled on the pedal to avoid chatter and roughness as noted above. How rough do you plan to be on the clutch for the track event? Are you just looking for durability?

It's a two day track day event GRIDLIFE BRO! (I'm just doing HPDE not time attack or drifting or anything) but the last drift event I was at it would slip bad (smoke coming in the cabin bad) any time I tried to use 4th. Seem's to be fine 2nd and 3rd. It's a fast track so I will definitely be needing 4th and possibly 5th, but I won't be dumping the clutch to get it sideways like last time

terms of durability I just need a clutch that will hold the power level I want which is ~330-350 whp and probably low 300tq. I would prefer harsh engagement over a heavy pedal

I daily an fm2 and I don't think it's heavy at all. I have an MSM so according to the numbers posted earlier it is barely heavier than what my stock clutch was. I actually find it very easy to modulate because it has some resistance in the pedal instead of being floppy like some lower powered stock clutches can be. However, I am a man and I don't skip leg day so YMMV.

EDIT: I should say I HAVE DD'ed this clutch. The miata is no longer my DD but it was for 60k miles, much of which was with the fm2 clutch.

Yeah, my FM2 clutch isn't bad at all. Heavier than stock but not as bad as my Mustang clutch was. Far better drivability than any puck clutch I've driven - OE level progressivity I'd say. I'd rather a heavy clutch you can release smoothly than a lighter clutch you have to ride in order get a smooth takeoff.

i currently have a Competition Clutch stage 4 in my NA. It sucks in traffic. I keep telling myself I need to man up, plus it keeps people from asking whether they can drive my car. But at night, when I quietly cry myself to sleep, I wonder if I could pair a stage 3 solid disc with my stage 4 pressure plate and still handle 300 whp?

Don't waste your money on FM products. Spec, Competition... all equally low quality.

949 did the legwork to obtain much higher quality parts for their clutches.

Wait for the 949 sprung 4 puck. I'm driving on stock power levels with it, zero chatter. Normal clutch pedal pressure, narrower engagement, and slightly grabby, but how a clutch should be. A little noisier than stock on decel, on top of just a lightened flywheel.

What's your basis for the 'FM products are a waste' line?

Also, don't you think it's a bit strange that you're giving advice on a clutch that you're using at stock power levels? Have you ever driven one of them at anything resembling the OP's power output? i.e. what's your basis for the recommendation outside of a complete trust in Emilio? Not that there's anything wrong with that...

Well, I should have said, don't waste your money on parts that FM resells. They purposely use low cost parts. I have had nothing but early parts failures from them. clutch slaves (two of them rusted out and leaked in under 6 months) throw out bearings/release bearings (one early failure and the replacement was defective) pressure plate (defective and was causing clutch slip with stock power levels)

I just tell people to steer clear of their low cost high volume high profit parts. Just my opinion and experience with them.

I've gone though 3 clutches in 3 years, and I'm finally happy with the sprung pucked 949 clutch. They have a lower profit margin, much higher quality components.

Sure I only have stock power levels, but I'm just giving my input on clutches. I don't want other people to deal with the crap I've dealt with, just trying to look out for members if I can help them. If I'm wrong, fine, but I'm still steering people towards the higher quality clutch.

I wasn't doubting you. I was just curious as to your rational after all these folks were recommending the FM2!
