Grim,
It is alot of CF lol
As far as bouncing the car back, it never did it at speed, but we did hit numerous prking blocks nd curbs at anywhere between 1 to 8 mph and the car would literaly bet pushed back, the only damage that ever happened to the cf becuse of it was slight chipping and scratching of the clearcoat.
CF truly is great strong material and there used to be a few videos of guys jumping off the roof of their house and landing smack dab in the middle of the hood and not cracking or shattering it. ( I wouldn't recommend it since any resin based product only has so much give before it starts cracking and fracturing)
