BMW X3 G45 PR-1 Wide Track Arch Kit by Trevora (2025+)

BMW X3 G45 Pre-Preg Carbon Fibre Wide Track Arch Kit by Trevora (2025+)

Transform the stance of your BMW X3 G45 with the Trevora Wide Track Carbon Fibre Arch 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 pre-preg carbon fibre construction, each arch extension provides exceptional rigidity, lightweight performance, and precise surface consistency. Customers can choose between a high-gloss exposed carbon fibre finish or an unpainted carbon fibre version, allowing full paint-match customisation for OEM or bespoke builds.

Available Finish Options
