does the rear wing ACTUALLY provide any benefit?

areodynamic imbalance ment that the Audi TT was suffering from highspeed oversteer issues. Which was in part solved with a small spoiler. The TT still was running positive lift, just the small addition of a rear spoiler added some rear downforce reducing the rear lift, and bringing the car into better balance.

few road cars have actual downforce, but that doesn't mean that spoilers, splitters, etc don't help by bringing the lift closer to 0.

Audi's Electronic Stability Programme, and rear spoiler were added, along with suspension modifications. All changes were subsequently incorporated into future series production versions of the car.
