just a few more loose thoughts... moon discs... just any round plate that could seal of the rims basically... if they help on normal cars where the wheels look fairly aero friendly they should do something on these big wheels... than again they'd have to be strong for off road stuff.

next, perhaps a bridge to far, but not impossible is just make a whole new roof/windshield. it's involving, but given the fact the windshield will just unbolt (right?) and the vehicle doesn't have a fixed roof, means it won't involve gutting the original vehicle.... a plexiglass bubble would be cool (but like i said, probably not really practical)

on a more modest basis perhaps you could redesign the windshield to have more curved sides.... maby it's possible to saw the whole windshield assembly including the a pillars from a wrecked car and fix that? a saab 900 (don't gut a good one please) would be an interesting candidate, but a crashed metro might be nice too.

another idea is to install two lengthwise rollbars that from the A pillars and curve back all the way.. a fabric cover over these would also form a nice aero shape...
