The Honda S2000 spins the right way. Even comes with a RWD transmission - the transmission is big though. I am sure you know of this site already, but have you checked
LocostBuilders There's a ton of useful information there..
If you want good fuel efficiency, the Super 7 is a pretty horrible choice though. It has some of the worst aerodynamics you could imagine, and would need quite a bit of redesigning to improve that..
