Engineered to Match the BMW 3 Series G20/G21 M-Pack Platform
These rear side splitters are developed directly on the BMW 3 Series G20/G21 M-Pack using high-resolution 3D scanning and CAD design. The result is a pair of components that follow the sculpted rear bumper corners and lower valance contours with high precision, delivering clean panel gaps and a factory-grade visual integration.

By extending the lower edge and widening the rear corner profile, the splitters visually lower the vehicle and emphasise the 3 Series’ broad, muscular stance. When combined with a rear valance, diffuser and side skirts, they complete a cohesive, performance-driven aero package that transforms the rear three-quarter view.

Material & Surface – Built to Last
• Automotive-grade ABS with UV additives
Manufactured from high-quality ABS enhanced with UV stabilisers to help resist fading, discolouration and material fatigue over time, even on vehicles used daily in mixed weather conditions.

• High-gloss black finish
  Supplied in a premium gloss black surface that is ready to install out of the box. If a custom colour or body-colour finish is desired, the parts can be refinished by a professional body shop (primer recommended) to match other exterior details such as diffuser inserts, mirror caps or roof trims.

Fitment & Installation
• Model-specific design for 100% vehicle-matched fitment on BMW 3 Series G20/G21 M-Pack rear bumpers.
• 2-piece left/right kit that follows the lower rear bumper edges and integrates with existing styling lines.
• Designed to mount along the lower bumper corners with precise alignment points for a neat, symmetrical installation.
• Supplied with a dedicated fitting kit and installation guide.
• Professional installation is recommended to ensure correct positioning, secure fastening and an optimal visual result.

Quality & Confidence
Each production batch is checked for dimensional accuracy and surface quality before leaving the factory, ensuring consistent, repeatable fitment for workshops and distributors.
