This rear diffuser from Apex Aero Design transforms the rear of the BMW 4 Series G26 Gran Coupe with a sporty, aggressive design reminiscent of the M-Performance finish. Made from high-strength ABS plastic with a gloss black finish, it adds visual presence with no need to modify the original bumper or visit a workshop.

Features

  • Flexible, durable ABS plastic — Absorbs minor impacts without cracking and withstands temperature changes without deforming.
  • Factory Gloss Black finish — Durable glossy black, with integrated UV protection to prevent yellowing.
  • Perfect fit via 3D scanning — Designed to the exact geometry of the G26's OEM bumper.
  • Drill-free mounting — Secured with automotive-grade 3M adhesive, included in the kit.

Why choose Apex Aero Design

Apex Aero Design manufactures digitally scanned aftermarket aerodynamics, with factory finishes and materials stronger than fiberglass. Compared to budget replicas that yellow or crack over time, Apex's flexible ABS maintains its shine and shape even after months of sun exposure and frequent washes.

Frequently asked questions
