fins are probably bad

I am reasonably sure fins are bad in almost all cases

Aerohead and Darin will probably swoop in on us for even discussing them

the caddy fins probably create tip vortices (similar to picture below) off of the top of each fin as the air tries to flow around the car. That would basically be like running down the road creating little tornados of lost energy.

why do you ask, are you contemplating some fin mod?
