If you're running a larger diameter aftermarket exhaust on your BMW F8x M2, M3 or M4, the factory underbody brace is the limiting factor.

The MMX Underbody Chassis Brace solves that. Precision CNC machined from billet 6061-T6 aluminium, it replaces the OE brace and provides an additional 15mm of exhaust clearance, eliminating contact risk whilst maintaining original ground clearance. Beyond clearance, it also reinforces a key structural area beneath the car, improving chassis rigidity and dynamic performance on road and track.

Direct fit. Original mounting points. No cutting, drilling or permanent modifications required. Fully reversible.

Still running the factory corrugated intake pipes on your G8x?

The MMX Intake Pipe Kit for the G8x BMW M2, M3 and M4 is designed to improve airflow between the factory airbox and turbo inlets, replacing the restrictive OEM pipework with a smooth, constant-diameter aluminium design.

Direct OEM fitment means no modifications, no additional hardware, and straightforward installation. Just improved airflow, enhanced efficiency, and an engine bay upgrade worthy of the S58.

Our G87 M2 development car was back on track for final testing of a range of upcoming G8x hardware, hosted by Adrenaline Collective and Destination Nürburgring Track Days.

Unlimited track time, countless laps, then driven home again. Exactly how it should be. More on the new G8x hardware soon.

Track-ready braking performance without compromising everyday road use. Our MMX 2-Piece 380mm floating front discs/rotors for BMW F8x deliver improved cooling, lower weight and consistent stopping power when pushed hard.

Utilising a two-piece 380mm x 30mm floating design allows our disc and hat to expand radially and axially as they absorb heat generated from hard use, avoiding the most common cause of warping and cracking seen in single-piece discs. Due to the efficiency of this design, MMX discs last considerably longer than factory discs. The friction surface features our trademark groves that increase bite and remove debris from the pad surface giving the perfect balance between brake feel and longevity.

Matching rear MMX discs and MMX brake pads available separately.
