Functional Rear Wing...what to look for?
I'm thinking about exploring aerodynamics for my E46. I think I understand how I want to mount a plywood front splitter...bolt it to the frame rail in the back and then use some struts to hold it up in the front. Use some hardware and elongated holes on the bottom on my front lip so I can adjust the lip to stick out less or more.
Now my question is what qualifies a rear wing as more or less functional? Is it the height relative to the rear decklid or roofline? Width? Angle?
