Ground effects. Ok so i bought a gto that was a show car, so it has all kinds of parts on it that i don't know who made them. I have the ground effects on the side of the car. They are not the stock ones though. I can't get pics up right now, so i can only describe them. The look the same, except toward the very front of the ground effects near the tire there are these two vent looking things. Anyone have any idea who would make these.
