Sorry to hear about the car. Why do you like the act kit? I don't know much about evo clutches. I've heard stories about the twin disk clutches shuttering when you shift gears.
I think the main reason I chose the ACT is because it is the cheapest clutch out there that can withstand my setup. I really can't justify spending $1400 on a twin when I'm only making 400whp or so. The ACT HDG6 that I'm planning to get should hold 500whp just fine; I know evos that are making 600whp++ with the same clutch.
Here's a post on a triple that exploded taken from evolutionm.net. It sure can happen to a twin also.
