Well I had the dealer install the oem front lip so I don't know if it will affect the way we remove the front bumper. I understand there are 8 screws/nuts at the bottom holding the front bumper - does this still apply when removing the bumper with chin spoiler? Am getting fog lights installed in the lower grills tomorrow
