Just the bumper by its self will not look right IMHO. in fact even with the stock spoiler it needs some help. Here is a pic of my car and what I did was order the carbon signal add on spoiler that was molded to the stock spoiler that gave it that extra 2-3inches that I felt made the rear look right. Side skirts are a must to bring the body lines lower to fit the rear. As far as the front you could bet away with just a lip kit like the stillen, etc but to really set the car off going with the amuse, stillen, or even the carbon signal raptor like mine is the only way to go.
