Christ,that would be a good cleanup to the rear and get you in better position for more daring mods later.Also,have you considered integrating fairings for the rear tires into your valance? Those would clean things up even more.--------------------- And another thought looking at your photo.The rear windshield is blacked out on both sides and you have no vision there.If you made flat panels which mated to the contour of the hatch,which projected straight back a couple feet,with a top which sloped down like the Kamm roofline,and a bottom which came up like a diffuser,you could capture a big chunk of wake,and the surrounding air would skid off the attached vortices formed inside the voids outside the panels,and off the top and bottom panels.----------- It wouldn't be as good as a very complex and difficult to build formal boat tail,but you'd see a benefit at the pump.---------------- Continuum Dynamics has already proven the concept under a DARPA grant from NASA for an 18-wheeler.You could build it over a weekend probably.
