Brembo 06-12 325i (Excl. xDrive) Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Drilled-Red

This Brembo GT Big Brake Kit for the rear of your 2006-2012 BMW 325i (excluding xDrive models) includes everything you need to significantly upgrade your stopping power. You'll get a pair of red 4-piston GT calipers, two-piece 345x28mm drilled rotors, and all the necessary hardware to complete the installation. This kit is designed to replace your factory rear brake components with a much larger and more capable setup, making a noticeable difference when you need to slow down quickly.

The calipers in this kit are cast aluminum, which helps keep unsprung weight down while providing a solid foundation for the pistons. The 4-piston design offers more clamping force than stock, working in conjunction with the larger 345x28mm two-piece rotors. These rotors are drilled, which helps dissipate heat and gasses, keeping the pads from glazing and maintaining consistent braking performance, especially during repeated hard stops. The two-piece design allows the rotor hat to expand and contract independently of the friction surface, reducing the risk of rotor warping.

Installing a big brake kit like this is a substantial upgrade for your 325i. It's ideal for drivers who push their cars hard, whether on the track or spirited street driving, and demand more from their braking system. While this kit is designed as a direct replacement for the factory brake lines, it's always a good idea to inspect your existing brake lines for wear and tear, and consider upgrading them if necessary for optimal performance. Refer to the manufacturer's installation instructions for detailed guidance.
