Leave them alone if you plan on running the side skirts in your sig. If you fill in the bumper, gotta fill in the side skirt vents too.

 

Fill in one of them (the front one) and just leave a pair of gills there, whether they're actually cut out or not. Doing that would throw off quite a few people who are otherwise familiar with your bumper

 

So just to let you guys know the front bumper is getting shaved and filled, (just the side vents) I should have completed pictures by the weekend as the car is going in on Monday. I am also doing a few extra things that you'll have to wait and see ...........
