I am working on modifying the rear bumper of my wife's A4 Avant 3.0 Quattro. A little while ago I picked up an oem S4 rear bumper and I started customizing it. I made a digital 2D design (I suck at CAD). I want to make the rear a bit more aggressive looking, but also a bit distinctive from the rest.





















I've done this before with the previous A3 8P of my wife which worked out quite well.
