Choose your brake rotor style (slotted, bi-directional slotted, cross-drilled).
This kit will fit the front axle on G20 330i, 330ix, M340i, M340ix (2019+) and G22/G23 430i, 430ix, M440i, M440ix (2020+).
Note: Brembo big brake kits are custom assembled after order is placed. Please allow 2-3 weeks for delivery.
Wheel Fitment / Clearance NotesWheel Clearance will need to be confirmed prior to finalizing your order. As with all big brake kits, you will need to confirm the caliper will not make contact with the wheel. We strongly recommend using the printable template (found in the link below) to measure. 380mm rotors will typically require use of a 19" wheel.
