StopTech BBK 2000+ BMW M5 355X32 Front Right Replacement Hat

This is a replacement rotor hat for the front right side of a 2000 and newer BMW M5, specifically for a StopTech Big Brake Kit (BBK) that uses a 355x32mm rotor assembly. The hat is the central part of a 2-piece rotor that the friction ring attaches to, and it's designed to bolt directly onto your vehicle's hub assembly. Having a replacement hat means you can refresh your existing BBK without needing to buy an entirely new rotor and hat combination.

This hat is made from aluminum, which helps keep the overall weight down compared to a traditional one-piece rotor. It's built to work with the StopTech 355x32mm friction rings, ensuring proper alignment and heat dissipation when paired correctly. Having a well-made hat is important because it provides a stable mounting point for the rotor ring, which is crucial for consistent braking performance, especially under demanding conditions.
