Brembo 06-12 325i/328i (Excl. xDrive) Rr GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted Type3-Black

The 345x28mm, two-piece rotors in this Brembo GT Big Brake Kit are cast iron, a material chosen for its excellent thermal properties and durability under heavy braking. This kit is specifically designed for the rear of your 2006-2012 BMW 325i or 328i, excluding xDrive models, to significantly improve your braking performance. The four-piston calipers are a substantial upgrade over stock, offering more clamping force and better heat dissipation, which is crucial for maintaining consistent stopping power during spirited driving or track use.

Brembo's GT Big Brake Kits are well-known for their ability to handle the demands of performance driving. The calipers themselves are constructed from cast aluminum, keeping weight down while providing a solid foundation for the pistons. These calipers feature a black finish, giving your vehicle a more aggressive look behind the wheels. The Type 3 slotted rotors are designed to help vent gases and heat away from the pad surface, which helps prevent fade and keeps your braking consistent, even under extreme conditions. The two-piece rotor design also helps manage heat and can make replacement easier down the line.

When installing this kit, you'll want to ensure you have the necessary tools and a good understanding of brake system maintenance. It's always a good idea to consult the manufacturer's installation guide for specific torque values and procedures. This kit is a significant upgrade, and you'll likely notice a considerable difference in pedal feel and stopping distance compared to your factory setup. Remember to properly bed in your new brake pads and rotors according to Brembo's recommendations to achieve optimal performance and longevity.
