Why Choose These Extensions?
Rear bumper extensions are one of the best bang-for-the-buck exterior upgrades. They add depth and aggression to your rear end, making your BMW look lower and wider without being over the top. Whether paired with a carbon diffuser or on their own, these extensions create a sharper, more refined finish for your build.
