Where are all of these IS F's in PA? I'm there once a month near Philly and I've only seen one IS F on the road in obsidian black.

To the OP, looks good.

LOL at the EVO's VG, it looks almost the same (but underneath the car).

It looks good, and it is growing on me too but one question, what will it do at speed, will this diffuser add lift to the rear of the car? Probably the only way to know is to get the car into a wind tunnel.

Good question what it really does.

The Diffuser (properly designed and matched to the car) is designed to do the opposite of lift to the rear of the car. It is designed to increase traction at high speeds.

I think this diffuser was really designed for looks rather than actual traction gain. I don't think the designer/manufacturer spent wind tunnel testing to determine that.

I know if placed properly were there is air flow separation they can be functional on top of the car. The EVO has them and my buddy has some on his Supra. Aside from all the claimed benefits, he did notice that his rear bumper and window don't get as much dirt stuck to it as before. These could work on the IS-F too, but to be placed properly they would have to be stuck up on the roof about the same level as the sharkfin which would look silly. As for these type of vortex generators on the bottom rear of the car I can only imagine it's for looks only.
