| Message | bumper look too heavy, making the car look a little fat from the rear. The one Nismo kid made may look a little weird because of the fins looking like they protude farder than the bumper and we won't be doing that when we start designing our diffuser, since we will be trying to follow the angle and direction the base bumper has. When we started this project we kept in mind that we were going to use the same area we posted on a picture a couple of posts above. IMO, using that area, like Nismo kid did, eliminates the heavy appereance that your design has...Just thinking about it, the Kaminari and WW bumpers has a closer idea to the one you are looking for and they booth look a little too big on our cars, while not looking bad, tho.
