as an aero aid they help very slightly towards fuel economy too.
These are wind tunnel tested, and developed.
Having said that, if you were to cut them off, you probably wouldn't notice the difference.
I believe you. But also I believe "if you were to cut them off, you probably wouldn't notice the difference". Then so what's the point?

In racing, where every little bit counts, why dont you see these flaps on race cars, or high end car like Lambos or Astons?
