This is the BMW M Performance front and rear brake upgrade kit for 2019- G20 330i/M340i and G22 G23 430i/M440i. This kit uses calipers and discs that are larger much larger and offers better cooling. The front caliper looks massive behind the wheel and accommodates the larger disc. The entire kit has been engineered specifically for the G20/G22 chassis. All components are a direct bolt-on replacement for the stock G20/G22 brakes. New dust shields are included that clear the larger front brakes. The pads and rotors have been specifically designed as a sports upgrade with stronger bite and better performance than original G20/G22 brakes. BMW recommends having the brake/DSC module re-coded to match these bigger brakes. This can be done at the BMW dealer.
