Sorry, not too crazy about the wing, but your car's mad clean. I like it, excellent work.
To ppl flaming the wing, it helps by extending the streamline of the car. creates less turbulent air between the wing and the back of the car. The eddies formed by the turbulent air at the rear of the car without a wing actually creates more drag and does make for a slower car. Mugen dun make no rice.
MAD PROPS TO U DOOOOOOD!
