Its not foam CsGTS. If you look at the top of the wheel wells, it would have been flattened against the tire by gravity. Its cotton balls squished together to look like smoke(from your tires spinning so fast, ya know?)
Its gay, retarded, and takes away from the look of the car.
Why ppl continue to do it? Who knows. Why do ppl do half the stuff they do, like "diving board" size rear spoilers?
QTRMRL_1, I think the hot naked woman would get more attention faster than the ghey white cotton, am I right?
