Protect your G8x's vulnerable front-mounted radiator from road debris, stones, and kerb strikes with the MMX Underbody Radiator Guard — a precision-engineered stoneguard designed to shield the radiator core from damage without restricting airflow.
G8x M-Cars position the main radiator close to the front splitter and road surface, leaving it exposed to debris kicked up from the road — particularly at speed or on track where stone strikes are common. Radiator damage typically requires expensive replacement, and even minor punctures can lead to slow coolant loss with potentially serious consequences.
The MMX guard bolts directly to the existing underbody structure with no drilling or modification required. Precision-engineered for the G8x chassis, it provides full radiator coverage while maintaining the required airflow to the cooling system.
