MMX Performance Front Wheel-Arch Clearance Grilles for G8x BMW M2 / M3 / M4 [MMR45-1602]

MMX Performance Front Wheel-Arch Clearance Grilles for G8x BMW M2 / M3 / M4 [MMR45-1602]

MMX Performance manufactures replacement aluminum grilles specifically engineered to provide additional clearance for modified G8x BMW models running lowered suspension, wider tires, or wheel spacers. Designed to preserve airflow while shielding against road debris, each grille features a precision laser-cut hexagonal pattern finished in a durable black powder coat. The grilles mount securely using four fixings per side, and the kit is supplied with all necessary hardware. For installation, the vented section of the factory arch liner must be cut and removed to accommodate the new components.

Development

• MMX Performance identified a common issue with the factory BMW front arch liners — the integrated vented section, designed to release air from the front bumper, offers minimal clearance between the tire and vent fins. While this isn’t typically a concern on stock vehicles, modified setups — such as lowered suspension, wider tires, or the use of spacers — can cause the tire to contact and damage the plastic fins. In severe cases, this damage can extend to the tire or even the radiator. MMX Performance’s replacement grilles address this issue by providing additional clearance while maintaining proper airflow from the bumper, just as the original design intended. Tested extensively across lowered vehicles and varied tire configurations, these grilles deliver consistent performance without compromising fitment. Constructed from lightweight yet durable aluminum, each grille features a precision laser-cut hexagonal pattern and is finished in MMX’s signature black powder coating for long-term resilience. It’s a smart, functional upgrade for G8x BMW owners seeking added clearance without sacrificing airflow or appearance.
