Product Description

Upgrade the rear braking performance of your BMW M5 (4.4 L V8 Biturbo, 2011-16) with the SHW Performance BRL48171 rotor. This unit features a generous 400 mm diameter and 36 mm thickness, delivering a significant braking surface area and thermal capacity. The cross-drilled high-carbon construction improves heat management and reduces the risk of brake fade during high-stress driving.

The two-piece, internally-vented design reduces unsprung mass and improves rotor cooling compared to many one-piece units. With corrosion-resistant hub treatment and precision machining for flatness, this rotor preserves OEM alignment and pad contact while providing a performance upgrade. Installation is direct via the original mounting hardware, following standard torque and pad bed-in procedures.

This rotor is ideal for performance-oriented drivers of the BMW M5 who demand both fitment precision and elevated braking capability - whether for spirited daily driving or occasional track events. Verify your hub bore, pad compatibility, and mounting hardware to ensure the correct fit.
