Wing

For the wing, I chose a 70” x 14” element with large end plates from RHR Performance. Since no one made a mounting solution I liked, I went it alone and fabricated my own. I first mocked up the mounting interface to the rear deck lid (which wasn’t easy since there isn’t a flat or straight surface on that damn lid), then suspended the wing in position and mocked up the mounts using cardboard. Once satisfied with them (much trial and error here…) I cut them out of 3/16” aluminum plate. These I had TIG welded at a local fabrication shop. Spoolgunning with a MIG wasn’t going to cut it! The wing is 2” above the roof line and half its cord past the bumper.

Multiple angles to deal with.


Made a jig to suspend the wing. Trial and error on uprights. Cardboard is cheap...


Using 3/16" particle board to make final template.


Bits ready for install...


And now the money shots...


Very happy with the results.






Gotta love the distortion in this view. Looks like the wing is 12' wide...
