Roof Spoiler...Aero effect?

Really, it's called the Ghetto-effect. Your car won't go any faster but your IQ drops 20-40 points, instantly after installation.
The wings and spoilers put on passenger cars have no aero effect except for:
1. The massive WRX Sti / Evo wings, which probably add some downforce, and
2. The little pop up spoilers on cars like Cayman/Boxster, and then only at VERY high speeds (well above any legal speed). They added a fixed spoiler to the back of the Audi TT because the early un-spoilered ones experienced lift and instability at very high speeds.
