In a 90-degree, sidewind gust, the fin would be in the range of Cd 1.15, same as a sheet of plywood. That far back, behind the rear axle, she could present quite a yaw-moment, good, safety weather-vaning, flat-out at Bonneville, but maybe freaky out on the open road.
I've driven Spirit in pre- lethal, supercell cyclonic inflow, out in the Texas Panhandle, at 75-mph, and had no handling issues.
If you have a chance to safely test for stability, it would be very valuable data.
