Venting of the bumpers have been big in the Japanese vip scene for the last 4 years but have still to catch on here in the states. When done to flow with the rest of the build and in moderation, it can look really clean. Brabus notably made the 2 slits in the bumper popular in the early part of the 2000’s and are given credit for making it hot in the vip scene.
El Presidente was not scared to cut up his rare Auto Couture half bumper up on his Jaguar. Rather than cutting two ovals, he went with the slanted rectangles to better go with the lines of the bumper. This should look real clean once painted.
