RE: graphite or aluminum
there are several different grades of CF. F1 carbon fiber is hand layed wiht the strands going in several directions and it is very thick. this is a very strong arrangement. however, many shock towers and suck use a lower grade. some of them use a graphite filler in the middle and the weave just onthe outside layer. CF can be very strong and i believe it could be a good chassis, i just have my reservations about mixing aluminum and CF. i know bonded CF and aluminum have corrosion problems and expansion rate issues.
but, i would love to see high quality CF chassis and towers and steering playes.
