I have an ACT XTSS right now and considered an Action Miba sprung 6 puck to use with the ACT pressure plate, but $200 is pricey when I can get an ACT 6 puck for $100 shipped, and an ACT organic for $140 shipped. I don't understand the gouging going on for just a clutch disc! I've driven a '94 RX-7 with an ACT 6 puck and hated the horrible chatter, so that's out of the question. I'm pretty happy with the XTSS, but right now I'm only at 235whp. If I reach my goal of 350whp, and replace the clutch disc with a new organic, since the tranny will be off anyway, how long will it hold? If any of you high horsepower guys use the XTSS, I'd like to hear how much power you're putting down and how long you've had the clutch.

 

im running a act steet strip cluch on a boosted b16a, putting down 380whp, ive had the turbo and clutch for over 3 years, but have only put about 15k miles on the car since ive had it. the xtss should work fine, mines holding up so far.

 

i find that's the best combination for the streets

 

i really like the act 6 puck. it only chatterd in my car for a week or so. i'm not sure if It was wearing in or if i got usd to it but i haven't had it chatter for months now. it holds quite a bit of tq and doesn't have any of those pesky springs to break and jam up the PP. $.02

 

the ACT XTSS clutch is good until 319 ft/lb torque which on on a honda is around 450whp give or take depending on the setup

 

the XT pp has to be real fun on the street...
has two start modes: stall or spin

 

I appreciate all the replies. I'll stick with the organic disc.

You mean squeal or spin! It makes strange noises sometimes when starting from a standstill, but still holds. I like the pedal pressure.
