The manufacturers are doing such a good job of developing these cars now that there is very little that companies like Schnitzer can offer to improve on them. Personally, I think the wing looks tacky and as someone who does a lot a track days, I can tell you that most people on here can't even drive a car with 350 hp to 7/10s of its limit so l get a kick out of those who whine about needing more power or that an aftermarket splitter will make a difference when they are parked at a car meet
