Air duct inlet

To transport the air to the brake ventilation outlet, a suitable intake is essential. The M2 Competition already has intake ducts in the front bumper from the factory, but these end in the middle of the wheel arch. To prevent the air from swirling randomly in the wheel arch, we developed an extension for the air duct that can be installed with minimal effort. It guides the air around the wheel and connects it to the outlet via a hose.

For many vehicles, brake cooling is recommended even under moderate loads, even off the racetrack. This not only improves braking performance but also drastically reduces wear on the friction partners. Our brake armature plate channels the airflow to the center of the brake disc, harnessing the turbine effect to cool the disc from the inside. We direct the airflow at a specific angle to the disc to avoid scattered losses and utilize the available air volume with maximum efficiency. The lightweight construction combined with powder-coated aluminum makes the brake armature plate sufficiently strong, yet light and durable. In addition, the bearings closest to the brake disc are shielded from heat to increase their service life (if necessary).

IMPORTANT: Different models vary slightly in wheel position, coupled with different chassis geometries and wheel/tire combinations, making it impossible for us to cover all variants. In the worst case, the wheel could touch the ground slightly when fully turned (which should only happen when parking), which will not cause any tire damage. In this case, we would ask you to refrain from making the last 1/4 turns of the steering wheel.

The inlets can be supplied in grey, different from the picture.
