I would have thought that if they were good for aero, it would be best to have these on all 4 wheels? If you were only having one axle with covered wheels, surely makes more sense to cover the rears (leaving fronts open for brake cooling?)

I'm not saying these guys are wrong, i'm sure there is a whole bunch of work to come up with this set up but not sure if i understand the logic?

Any one care to comment?

GOOGLE for an image of the 1987 OLDS AEROTECH long tail,land speed record car.This car made more concessions to drag reduction.
