Brembo 06-12 325i (Excl. xDrive) Rear GTR BBK 4 Piston Billet 345x28 2pc Rotor Drilled- Nickel

This Brembo GTR Big Brake Kit is specifically for the rear of your 2006-2012 BMW 325i, excluding xDrive models. It's a comprehensive upgrade designed to significantly improve your braking performance, especially if you're pushing your car hard on the track or autocross course. The kit features a robust 4-piston caliper paired with a 345x28mm two-piece rotor that's drilled for heat dissipation. This setup replaces your factory rear brakes with a much more capable system.

The calipers are forged from billet aluminum, which is both strong and lightweight, helping to reduce unsprung weight. The two-piece rotor design allows for better thermal management, as the aluminum hat can expand and contract independently of the iron braking surface. This helps prevent warping and ensures consistent braking performance under extreme conditions. The rotors are drilled, which helps to vent gases and moisture away from the braking surface, further improving grip and reducing fade. The nickel finish on the rotors adds a layer of corrosion resistance and gives the kit a clean, professional look behind your wheels.

Installing a big brake kit like this is a substantial upgrade, and it's important to ensure you have the right tools and knowledge for the job. This kit is designed as a direct replacement for your stock rear brake components, but it's always recommended to consult the manufacturer's installation guide for specific details. You'll notice a significant difference in stopping power and pedal feel, especially during repeated hard braking events.
