MMX Front Wheel Arch Clearance Kit – BMW M2/M3/M4 (G8X)
MMX Performance’s replacement aluminium grilles offer extra clearance for modified G8x BMWs with lowered suspension, wider tyres, or wheel spacers. Designed to maintain airflow and protect against debris, the grilles feature a durable black powder coat and laser-cut hexagonal design. They securely attach with four fixings per side. Note: Cutting and removing the original vented section from the OE arch liner is required for fitting. The kit includes all fixtures and fittings.
The Problem with Original BMW Front Arch Liners
A common issue has been observed with the original BMW front arch liners: they include a vented section intended to allow air to escape from the front bumper. However, the clearance between this section and the tire is often limited. While this might not pose a problem for a standard vehicle, modifications such as lower suspension, wider tires, or wheel spacers quickly exacerbate this small gap. The tire can then catch on the plastic vent fins, causing immediate damage. In some instances, these broken pieces may even damage the tire or radiator.
The Solution: Replacement Grilles
Their replacement grilles provide the extra clearance necessary for modified setups, while still facilitating proper airflow out of the bumper, consistent with the original design’s intent. These grilles have undergone testing on lowered cars with various tire configurations to ensure they perform as intended without compromising clearance.
Design and Manufacturing
Manufactured from strong, yet lightweight aluminum, these grilles feature a laser-cut hexagonal grid design for a clean, high-quality finish. They are then powder-coated with a durable MMX black coating, designed to withstand diverse road conditions.
Installation
Each grille mounts securely to the arch liner using four fixings per side, ensuring they remain firmly in place. They are supplied as a complete kit with all necessary fittings for straightforward installation. This offers a simple yet effective upgrade for any modified G8x BMW owner seeking a functional solution.
Please note: Fitting these grilles requires cutting and removing the original vented section from the OE arch liner.
