ive been thinking about getting a set of trailer fenders and extending them to cover everything except the bottom 3 or 4 inches of the tire. It would be attached to the spindle so it moves with the wheel.
You should be able to get a very tight fit and really minimize some turbulence, plus it would look awesome. To take it off to change a tire you should be able to jack up the car and unbolt it, my tires drop @ least 6 inches when i jack my car up.
what do you guys think?
