Acexxon G8X M3 / M4 Rear Reflector Insert Set - Horizontal Slat

The Acexxon G8X M3 / M4 Rear Reflector Insert Set in horizontal slat design offers a clean, modern alternative to the factory rear reflectors while preserving a true OEM+ appearance. Inspired by BMW motorsport styling, the horizontal slat profile delivers a refined, understated look that enhances the rear bumper without overstating the upgrade.

Finished in high-gloss black, these rear inserts replace the factory rear reflectors while maintaining a factory-correct fit and finish. Developed using in-house 3D scanning and repeated test fitting, the Acexxon G8X horizontal slat inserts are engineered for precise integration with the rear bumper so the final result looks intentional, clean, and properly aligned with the original body lines.

The G8X M3 and M4 rear inserts feature factory-style tabs and clips for a straightforward installation process with no cutting, drilling, or adhesive required. The gloss black finish pairs seamlessly with BMW’s factory high-gloss Shadowline exterior trim, delivering a cohesive blacked-out appearance across the rear of the G8X chassis.
