Fan Fin - Motor Sports (gambling)


A fin on top of the hood of an IRL car, behind the air box and just forward of the rear wing. The main purpose of the fin is not aerodynamic, but rather to have a large vertical surface to paint the car' s number on, in order to make identification of the cars at speed easier.
