Brembo 2021 + 430i/xDrive/ M440i/xDrive (G22/ G23) PISTA Rear Race BBK 2pc 380x28x54a 2pc Rotor T5

This Brembo PISTA Rear Race Big Brake Kit includes a pair of 2-piece 380x28mm rotors, designed specifically for the 2021 and newer BMW 430i, 430i xDrive, M440i, and M440i xDrive models (chassis codes G22 and G23). This kit is built for track use, offering a significant upgrade over the factory braking system for drivers who demand more from their vehicle during spirited driving or on the race track.

The PISTA series from Brembo represents their top-tier offering for track-focused applications. The 2-piece rotor design helps manage heat more effectively by allowing the rotor ring to expand and contract independently from the hat, reducing the risk of warping and cracking under extreme thermal loads. The specific dimensions of 380mm diameter and 28mm thickness are chosen to provide a larger swept area and better heat dissipation compared to stock components. While this kit focuses on the rotors, it's important to note that a complete Big Brake Kit typically includes calipers, pads, and lines; this specific product listing is for the rotor and associated components for the rear axle.

For those pushing their BMW G22/G23 to its limits on track days or autocross events, this Brembo PISTA rear rotor kit is a well-built component designed to handle the intense demands of racing. Proper installation by a qualified technician is recommended to ensure optimal performance and safety, as track-level braking systems require careful setup. Refer to the manufacturer's installation instructions for detailed guidance on mounting and break-in procedures.
