On the formula car, whats the advantage in using a cantilever style front suspension instead of a 90* inverted shock? I see that style on all open wheel cars. Im wondering becase Im toying with the idea of building a tube frame car similar to that using a 600cc CBR motor/trans.

Also I dont know how high the budget for the cars are or if it would help, but quaife(sp?) makes differentials for chain driven vehicals using motor cycle engines or similar motors. only down side its a $1k unit.
