RE: graphite or aluminum
maybe that chassis will work well, but i know there are potentially many problems. bonding aluminum and CF is always hard. getting the parts to stay bonded and not corrode has been a problem in the past. huge problem: different expansion rates as the chassis heats up from the engine. the chassis is a heatsink for the engine and does expand (alum expands quite a bit) and those two expand differently. maybe none of these problems will be evident, but they are potential problems in that chassis.
