Okay. I was thinking that the factory piece was on the bottom. As you can tell, I havent had mine out yet or the bumper off. I was thinking of the bottom deflector actually sitting below the bumper about an inch and pulling more air up from underneath. Curbs would be the biggest worry and since our cars are so short I am usually not anywhere close to them. I'll do some cogitating when I get to installing the LET HE from Woody.
