SimBa always spots the AI bots. Thanks!
Just a data point from an ancient FM2 user. I think the SM friction discs are very nice. Just replacing my current 4 puck with an organic. I was getting about a year of hard launches out of the organic, so I tried the 4 puck. I got about a year out of the transmission this time... It still holds though.
Their pictures don't do it justice, this is the organic one.


The other side is not as beefy.

Well I got the level 2 installed and have about 70 miles on it. I'm still doing break in miles (not sure how necessary that actually is, but whatever). I will say the pedal is very heavy. I should do a back to back comparison but it feels similar to the non-hydraulic clutch in the '63 Chevy pickup I have. Compared to the ease of the level 1 I'd say this is a pretty significant downgrade in that category. I'll give it some more time and see how I adjust to it. It's also a bit harder to tell what parts of the drivability/engagement should be attributed to the clutch vs the lightweight flywheel since this is my first time with one.

Overall I suppose I'm a bit indifferent to it. I won't be telling everyone how great it is, but I also don't think I'll find myself complaining about it

Yeah Lightweight flywheels in combination with a heavier pressure plate is definitely an acquired taste... And you never really grow to like it you just get used to it and accept it because of what allows for when you're actually driving and not at a stoplight. That's why I did a lightweight flywheel but a more standard clutch (ACT street stage 1). It's still easier to stall but the clutch isn't an on off switch and its barely above stock effort.

Your experience going from FM1 to FM2 is exactly the same as I had years ago when I upgraded. I also then had tons of problems getting clutch pedal hydraulics set right with the FM2 and not needing to be adjusted.

Overall I am now all in on the Supermiata Sport Clutches now. It's all I will use or recommend to my customers.

I think it's all perspective, coming from an act xt for the last 15 years (that clutch has lasted 3 different setups and was still going strong) I went with the FM2. Pedal feels the same and the clutch really similar. I'm not thrilled with the lightweight flywheel in traffic but the shifts are nice and the rev matching makes up for it.

I tried SM stage 1 and didn't like it. Way too light, felt like a stock clutch, or maybe even lighter.

My perfect setup would have a pedal weight somewhere in between the two.

Honestly having put some miles on the level 2 now I would probably recommend the level 1 to just about anyone who is pushing under 350 WHP. IMO that is a pretty perfect clutch and mine wasn't slipping at ~280 WTQ. Unless you really really need the extra 40(?) Crank TQ that the level 2 is rated for, I'd be sticking to the level 1 and praying that it doesn't grenade itself.
