BMW 135i Rear Bumpers

The rear bumper on your BMW 135i compact car is there to absorb the impact energy generated during a collision. That protects you and any other vehicle occupants from injury, up to and including potential whiplash effects.

Today, rear bumpers are usually made of either a polycarbonate or butadiene styrene cover that sits over a reinforcement bar, though steel bumpers -- while rare -- are still available. The reinforcement, or impact, bar, is commonly made of steel, plastic, or fiberglass composite.

Where your rear bumper differs from your front bumper is that it typically sits lower on your car, with cutouts and lighting elements to accommodate your license plate. Modern rear bumpers also feature sensors that warn you when you come too close to a nearby object as you're backing up.

Due to the nature of their role, rear bumpers tend to take more than their fair share of abuse. While scratches, dents, cracks, or dings don't always mean you need to replace your bumper, it's a whole different story when your bumper has detached or is in danger of falling off. That's unsafe, and may even be illegal. BMW makes the only rear bumpers that were designed for your car, ensuring the easy installation and precise, secure fit that you want.
