If your car looks like this example below, then you already have a clean sharp edge for the air to release from (which reduces turbulence).

However, that said anything which makes the body longer ratio wise is usually good.

These retreating edge treatments (found on hatchbacks and SUV's) seem to get more common and larger every year (see image below).

I have begun sketching up a Phase-2 roof wing which includes cab side returns. Just have to figure out how to export the sketches from my phone to my computer, and then I will post them.

I currently do not make a big distinction between a roof spoiler and roof wing. However I do favor the leading edge air-slot approach of the semi-wing, just have to prove it works better than a flush sealed edge - somehow.
