Rear Bumpers are basically the face of your car and few parts can change the look of a vehicle more than an aftermarket rear bumper. We carry aftermarket rear bumpers in hundreds of styles from the top name brands in the industry. When it comes to a custom rear bumper they can be produced in a few different materials. The most common material used for aftermarket custom bumpers is FRP (fiberglass reinforced plastic). FRP rear bumpers are most common due to the low cost of manufacturing thus having the largest selection. These bumpers are light weight and affordable but they are susceptible to cracking if you bottom out hard or run into a curb. One of the good things about FRP is that it is the most customizable and repairable of any materials used for aerodynamics.
