Yeah, I wondered why they put them all over the car. A golf ball is spinning and has to have them everywhere.
A kammback is in the future for Tank (82 fullsize stationwagon). It would be simple enough to make one with dimples, or rather would be simpler than dimples in the wagon. Of course its going to require A-B-A-C-A testing. No Kammback, smooth Kammback, and a dimpled Kammback of the same exact design.
I have been thinking about how to make the kammback/dimples. Before I say anything I am going to do a few tests on materials that fit my range of tools.
