I'd predict no noticeable difference on my '59 if the fins were lopped off.

Speaking of which, I've always been confused about the mechanism for the BAT cars' aero success regarding their fins. I can't figure how they work to lower drag and actually it seems to me that since vehicles are operating in crosswind conditions almost always, those huge fins would add sail area and leave trailing wakes. So like the '59, I wonder how they'd test sans fins.

Speaking of testing, perhaps the published Cd figures are erroneous? Bad figures have been put out there more than once...
