how could it not help in corners? I really dont get why people think wings are useless on FWD cars. do people think wings are to help grip under acceleration? as in less wheel spin? because thats not even close to the point. if you have wheel spin at the speed when your wing actually becomes effective enough to reduce it. you have an insanely powerful car.
a wing like this on a FWD car helps overall grip, but more so in the rear. personally im not sure this guy needs it. if anything i wouldnt be surprised if he would be faster with a little rear end instability to get the thing to point easier, as FWD cars almost always deal with a bit of an understeer problem.
but anyway, the thought that a rear wing on a FWD car is useless is pretty stupid. assuming its set up right, a FWD car, or any car for that matter could benefit from a rear wing and added grip.
