i notice that all of you who are having gaps problems havent fully installed the lip on your car..... you just put it on the car. you can adjust the gaps in the front buy pulling the lip all the way back onto the bumper. use 3m d/s tape and srcews. also once the lip is on in the front.....you can go over to sides and adjust the gaps more by flaring out the bottom part out a little. my lip fits fine and it is in c/f. ill try to dig up pic's of the lip.
