BMW X3 M50 G45 Pre-preg Carbon Fibre PR-1 Rear Diffuser by TREVORA (2025+)

Complete the performance transformation of your BMW X3 G45 M50 xDrive with the TREVORA PR-1 Pre-Preg Carbon Fibre Rear Diffuser — a motorsport-inspired upgrade engineered exclusively for the flagship M Performance variant.

Designed specifically around the M50’s unique rear bumper and quad exhaust configuration, the PR-1 diffuser enhances rear-end aggression while maintaining OEM-level integration with BMW’s factory body lines. The sculpted aerodynamic fins and extended lower profile create a wider, lower visual stance, delivering the unmistakable presence expected from a modern M Performance SAV.

Manufactured using advanced pre-preg carbon fibre with premium 2x2 weave construction, the diffuser achieves exceptional strength and lightweight performance while showcasing flawless weave consistency and a deep, high-gloss finish.

The PR-1 Rear Diffuser amplifies the naturally aggressive character of the X3 M50, visually emphasizing the quad exhaust system while improving airflow management at the rear of the vehicle. The result is a sharper, more planted stance inspired by BMW’s M Performance design philosophy.

Perfectly paired with the TREVORA PR-1 Front Splitter and PR-1 Side Skirts for a complete carbon aerodynamic package.
