I think with the Startech V8 with 420+ hp have proven something behind the functionality of the SRT-6 wing. With a much bigger displacement and faster engine, the Limited wing with the addition of another smaller rear spoiler made the Startech V8 possible!

Startech is a Mercedes tuner and with the speed of 420+ hp, why did they not include a whale type wing to be able to make the Startech Crossfire perform well and safe to drive?
