I have experimented with flush coroplast wheel covers. You can make a compass out of an old yardstick with a hole drilled for a screw to spin it in the coroplast and another hole for a sharpie marker. Cut them out with old fashioned tin snips. I used 3 wire ties each and just snipped them to remove them. I did a study of them if you search posts started by me. There was a slight improvement but I think I get more of an improvement from my homemade belly pan/diffuser.
