Race teams do this, so they can run higher speeds into corners (without losing the front end), and it also keeps the car stable at maximum speed on the straightaways.
Oh thanks. It seems like this would be something that would hurt aerodynamics, but I guess its more important to keep the front of the car from lifting up, lol.
So I guess the alms m3 which uses one is blazing fast then! Why did they need chains to hold it on?
