Wheel Well Covers Greatly Disappointing

[Mayhim]

After much fussing and fitting I made some nice sheet steel (20ga) skirts for the rear wheel wells on the CRX. They stuck out no more than required to clear the wheels--not more than an inch away from the wheels. They fit snugly in the opening and the attachment points were solid and sufficient.

Results - 10mpg less than without. Repeated 50mpg w/out. Repeated 40mpg with. I even tried air deflectors under and in front of the rear wheel wells. No change.

Oh, well. I can cut them up and use them for sheet metal repairs prior to painting it this summer.

And I was SO hoping they would do better. They did look cool, though.
