I was planning on getting some thin Plexi and using silicone sealant to hold them in place. sure, you'd have to peel them off when it's time to remove the tires, but it wouldn't be that difficult. And clear silicone is pretty cheap.

While Bonneville cars all have these wheel covers, I suspect they go a bit quicker than we do, and I think air resistance at 200 mph is 16 times the resistance at 50 mph (correct me if I'm mistaken--if it quadruples when speed is doubled, and I doubled the speed twice, 4x4=16, but I may not understand it fully)

Either way, aero drag is a HUGE factor at their speed. Not to say it wouldn't help, but I wonder if skirts wouldn't have a bigger benefit, especially at our speeds.
