I recentely put a ram kevlar disc and an aluminum flywheel with a stock pressure plate, have well over 500 miles on the car went to the strip today first launched at 2700 tires stuck car bogged, next launched at 3400 tires hooked clutch slipped, again lauched at 2700 hooked and bogged. I believe this kevlar disc should not be a problem but who knows where I question is the pressure plate i am only making 450 to the wheels but plan on at least another 100 so if I am having these problems now whats to come. Does anyone have any brands that they have had great luck with. Thanks
