Amazing build guys! The whole concept just looks so obviously fast that it makes me wonder why this isn't a standard configuration for a stream liner.
One thing catches my eye here, or I may not be seeing something that's right in front of me. (That has been known to happen
) The rear end axles look to be relatively long, with no support outboard of the differential housing, which is solidly mounted to the chassis. This area looks like it could use a little more beef to help stand up to the pounding of a rough track.
Maybe something like the support rod that runs from side to side under the diff on a Harley Servicar diff, with turn buckle adjusters on each end to provide preload adjustment. From here it looks like you could build it to fit inside the aero package.
Like I said, just an idea that's probably worth everything that you paid for it.
