Hmm, I actually kind of like it. It sort of simulates a wide body kit, but it's a very subtle change. I think it would probably look best on any car besides black. I'd say it's probably on a similar level as the "hood pop mod" where a few spacers are put on the hood mounting brackets near the windshield to provide a slight gap for hot air to escape at the rear of the engine bay toward the windshield. It's not for everybody, but it's a really cheap mod and it has a small effect, so if you decide to do it, more power to you. I'd kind of like to see it done nicely on a WRX, so if you go through with it, please post a pic or two and let us know how you did it.
