I envy your simple and reversible construction method. I made a similar one of coroplast for testing but I don't have easy attachment holes. Do you have scraps left to make flat coroplast wheel covers? Perhaps in the future you can extend your Kammback for a longer, removable tail. I have welded up a bracket that fits in my receiver hitch for this purpose but that is as far as I have gotten so far.

I agree that the %%%% add up over time!
I do have several pieces left over, I am thinking about wheel covers, not sure if they are worth the risk of unbalancing the tires.
I also had thought of using my towing hitch for making a boat tail support. I am not sure if I will make one though. If I like the Kammback I might make a longer one (or just add onto the length of this one). I can add another brace running across the top and sides (attach at the shock mount brackets). I would also extend the braces coming from the top (bolts where the OEM spoiler was). This would let me make it longer in a modular fashion and who knows where it will end uphttp://forum.ecomodder.com/images/smilies/biggrin.gif .
