BMW X3 G45 PR-1 Wide Arch Extension Kit by TREVORA (2025+)

Transform the stance of your BMW X3 G45 with the TREVORA Arch Extension Kit — a bold exterior upgrade designed to deliver true wide-body presence while retaining OEM design harmony.

Engineered to mount seamlessly onto the factory wheel arches, this wide track kit enhances the X3’s naturally flared bodywork, creating a more aggressive, planted appearance inspired by modern GT and touring-car styling. The extended arch profile visually increases vehicle width, perfectly complementing wider wheel and tyre setups while maintaining everyday usability.

Manufactured using advanced carbon fibre construction, each arch extension provides exceptional rigidity, lightweight performance, and precise surface consistency.

Finish

  • Unpainted Carbon Fibre
    Supplied in raw carbon fibre finish, ideal for lacquering in gloss carbon fibre or custom paint matching.

Key Features

  • Pre-Preg Carbon Fibre construction

  • Wide track / extended wheel arch design

  • Motorsport-inspired styling enhancement

  • Lightweight yet highly durable structure

  • Designed to bond securely to factory arches

  • Enhances stance and wheel fitment capability

  • OEM+ integration with G45 body lines

  • Designed and manufactured by TREVORA

Design & Presence

The fourth-generation BMW X3 G45 already features prominently flared wheel arches from factory to emphasise width and sportiness.
The TREVORA Wide Track Kit builds upon this design language, exaggerating the vehicle’s muscular proportions to create a more performance-focused silhouette without requiring full body modification.

Ideal for customers running:

  • Wider wheel setups

  • Lowered suspension

  • Performance aero packages

  • Complete carbon exterior builds

Compatible Models

The G45 generation shares identical core body architecture and wheel arch geometry across models, allowing wide arch compatibility throughout the range:

✔ BMW X3 20 xDrive
✔ BMW X3 30 xDrive
✔ BMW X3 30e xDrive Plug-in Hybrid
✔ BMW X3 M50 xDrive

(Compatible with Standard and M Sport exterior variants.)
