Between the front and rear tires, you can put in a catamaran which is a box between the wheels.
What you've described here is basically what Aerocivic has done here: he has deflectors in front of the tires, long parallel channels (like double sideskirts) running the distance between front and back tires along the outer and inner edge of the tires, and a mini boat tail shape after the rear tire.

This whole thread has been really informative for me as I consider what's best for my metro which already has a full bellypan.

I'm willing to build catamarans but I think doing the airfoil shape before and after front AND rear wheels like suggested in Post 11 (I imagine I should only angle the foil for the front wheels as air is traveling more head on by the rear wheels?) would might prove effective and would allow for better clearance of driveways and the like.

What do you guys think?
