/ 01 · OVERVIEW

Carbon fiber rear bumper extensions help give the rear end of your G8X M3/M4 a more aggressive, aftermarket look. These extensions are made of 100% genuine carbon fiber and help complement the already aggressive body lines of the G8X M3 and M4. Each piece is constructed using genuine, 2x2 carbon fiber. A high-quality clear coat comes standard to help prevent damage from harmful UV rays and minor road debris. Installation is relatively straightforward as all holes come pre-drilled. Simply line up with your existing OEM or Performance V1 rear extension and drill.

Instructions are not included, professional installation is recommended. Feel free to reach out to sales@horizonmotorsport.com with any questions or concerns.

Please note, that these are not cross-compatible between the M3 and M4. Make sure to select your chassis on the dropdown menu. This is not an OEM BMW part.
