I did contact them and the owner/proprietor is VERY interested in doing a FULL, and FUNCTIONAL aero package for our rides.
He is going to try and get a FiST into his R&D shop to do laser/CAD-CAM scanning/modeling, and 'virtual wind tunnel' testing on it, and see what can be done.
He DID say that there is a very fine balance between functional aero, and speed sapping drag, I believe in reference to the time attack style, 'big wang' rear monstrosities, so do NOT expect that, but hopefully something like what is used on the WRC/GRC, etc. cars.
I did have to 'bring him up to speed' on these cars though, since he did not realize how light they were, nor how much power they were stock out of 1.6L, and how much could be pulled out of the Ecoboost either.
