Ah. Well I wish I knew if it was any stronger that what I got. I emailed FM about this, haven't heard back yet. Stronger with a lighter pedal would be good selling point.

Same clutch I have, probably about the same age. It is rated right at >300 ft-lbs torque, although I don't recall the actual number (over 300, not very much over).

Unless you are running the 405 tq rated version then no it is not. The next highest rating for ACT clutches is 340 and the organic disc extreme is 271. The FM clutch sits above those with a torque rating of 353 and it operates well on the street which is a common complaint about the ACT clutches being on/off switches.

The 300rwhp miata I tuned a while back had an FM2 clutch. Felt great to me.

Bump!

Well I took it to the track tonight. Aired down my tires, dropped the clutch at 3,600 on launch control and it bogged. Did it at 4,000 and the clutch noped out big time, slipped really really bad. Had to coast it down the track and drive it home. Also damn do these things hook hard when aired down...

I think I'm going to try installing the 6 puck sprung hub on my existing flywheel/XT PP for now. That will be cheap and stronger than what I got. If it sucks, then FM2 I suppose, but it's more $$$.

Bummer. But at least you're having logical problems now

Indeed. Just ordered the disk, will be here Monday. ACT said I could just remove the old organic disk and swap in a 6 puck. But they said you can't go back to organic once doing that, which is fine.

The good news is, the car ran GREAT before the clutch let go. I got the launch control working great, and flat shift is better than ever now. Ran a 7.7something (7.70 i think...) with a passenger and a trunk full of tools/laptop and a **** 60' from bogging out of the hole. Something like 2mph slower than my previous best pass and I now have 70lbs more crap + a 250lb passenger at the time.

Should be racing again next weekend.

That's an 11.6'ish 1/4, pretty good! Are you trapping 95-98mph in the 1/8th?

Not last night it didn't! It was 92.something last night with the extra weight and slippy clutch. I looked at the datalogs and the clutch was slipping on every gear change from the first pass.... I just didn't notice with flat shift until it overheated and gave up on pass 3 at the launch.
