DONT DO IT...

First of all you should have used at least Vortekz Generators (shark fins). Air tabs have WAY to much frontal area to have a net positive effect, or at least a VERY small one. TRUST ME.

Second, It will not help since you are not attatching the air to anything. And thats what vortex generators are used for. In other words, vortex generators only help sedans in the most part and coupes if the angle towards the back is greater than 10 degrees. It does not work on hatchbacks, suvs, or trucks where the air just detatches anyway since there is not more body for air to attatch to... you will only create more drag.
