ACT HD with a street disc will be the clutch for 90% of street use. I've had one in my FC for......damn it i don't even know how long. Too long. Because its finally starting to slip @ 20psi (~400whp+++) Best guesstimate on street miles on that HD clutch.......50,000kms or so. Mines been in roughly that long (roughly, its been years) and has only this year started slipping at higher boost settings that net over 400whp. Thats mostly street miles, not pussy miles, just street miles!
You won't bend or break anything in the transmission with this clutch as far as the heavy pressure plate is concerned. Its only when you get into the extreme plate that things start bending. The extrreme PP's have stupid heavy pedals....if you need to hold more the 380ft/lbs at the crank - buy a twin plate.
