I've been looking all over for some aftermarket front bumper cover / fender set that actually improves aerodynamics. Most are just for looks and actually make it less aero.
I've found this 1 so far that looks good, for my EG Civic;
it looks like the bumper cover & fenders on this 3 piece kit flare out over the wheel wells, so if you kept the stock wheels maybe you could cover them up and still have room for turning?
my goal is to be as aerodynamic as possible and still be able to paralell park downtown. it would be great, I think, to have a detachable boat-tail to just use for long trips.
