From the way a pressure plate works, it seems those centrifugal weights should improve the clamping force as the rpms rise, by forcing the weights to the outer edges this causes the PP to acutally clamp harder down.

My ACT HD was rated at 200tq, which is like a 33% increase ( i guesstimate the oem clutch can hold 150), new one is rated at 90% increase, so should hold closer to 280tq....but we'll see how effective this this is.

one thing i wish was available, the clamping forces of all pressure plates. OEM, ACT, Centerforce, Clutchnet, Competition, SPEC, etc. Then one could just choose a damn disc he's happy with and call it a day.


You are running the Centerforce unit? I heard the weights have been known to come off the PP.

Hopfully it works out for you. Did you replace the ACT because it was slipping? Or you are expecting it to slip?

i had a cfdf on my fwd eclipse, loved it, but i never planned for big power in that car. I don't see any reason not to go with the act xtreme, they had a great rep in the dsm community and i haven't heard of a miata burning one up. for me taking the trans off again is too much of a pita to cheap out on a clutch

Yeah, CF Dual Friction.

My ACT HD could slip if i dumped it really hard in gear, tried once or twice....and it slipped once at 12psi with a passenger. Since i hated the ligthweight flywheel I decided to upgrade in antipation of more power. while i swapped the JUN with an OEM.

I have a Centerforce I on my altima for over 3 years and I've have no problems, other than a failed TOB, but that was a nissan part, no problems with the weights.

I was trying to find a cheap ACT XT, but this local deal came my way, barely used going to be a built spec miata, so i jumped on it.

I heard good things from them, so time will only tell, i'm just iffy on the kevlar thing.
