ACT Extreme pressure plate??? and flywheel step??

[becauseican]

Does anyone have any experience with the ACT Extreme PP?, I have searched but havent found much info on it. I am currently running the ACT HD PP and its great, but I think I need something to hold more power but I dont really want to go with RPS max due to crank walk issues.

What is the clamp rating?. I know the ACT HD is about 2400 lb, and the RPS is 3200 lb.

Also what is the correct flywheel step for machining?. I assume the 1jz uses the same step as the 7M?

I dont think act makes and xtreme pressure plate for the a70?

I used a .020 step i think. 1jzs use a 7m clutch so the step will be the same.

HPF lists an extreme PP with a street disk, which is rated for 590 tq.

I bought act extreme from speed solution for $551 shipped, Heres a pic.

HPF offers it with a sprung full face organic street disk, I am torn between this and the HPF Bronze disk.

That 6 puck solid disk would be harsh.

I have been eyeballing that exact clutch setup Randy, (ACT XTSS). I would be very interested to know how it is in real life. I'm tired of my harsh 6-puck.

act does not make an extream pp you looking at the w58 ones


why not just get hfp bronze or fermic clutch should do you well with a reg act pp

and yes the 1j has the same step as the ma70 just diffent fly wheel botl pattern that yuo all ready know about

you are wrong they do make an exteme and its in the car a week now you have to call them to get the part number as they do not list it on their web site. the also have a six puck with sprung hub and this is what i ordered. pressure plate is 2650lbs and is rated to hold 632tq with a six puck

I ended up buying and installing the ACT XTSS kit from A2 Motorsports (CKanderson) : ACT Xtreme pressure plate with ACT full-face street disc. The pedal is stiffer than the ACT Heavy Duty plate I had in there, but it is not outrageous. Street driving is not hard on my left leg, despite the extra push needed, and I'm assuming is not as stiff as an RPS 3200. And it is as smooth as stock! I'm still breaking it in, and hope that it lives up to it's handling rating of around 522+ tq, since I will be throwing around 400-450 crank tq at it regularly.
