^ I wouldn't. Looks fine as a functional race car but atrocious to me as a street car. IMO, the R8 is way too classy to be driven around with a wing like that on the street, functional or not. Let's hope Fast and Furious 4 doesn't get any ideas from this.

On older DTM cars you'd see a big vent on the flared door instead of the cut away fender, but nowadays the designers want to maximize the track width of the car, which means that they put the wheel as far out as the rules allow, so there isn't any extra bodywork on the side to use for a vent.
Looks weird, but is VERY functional.
