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

If you're looking to significantly upgrade the braking performance on your 2006-2012 BMW 325i or 328i (excluding xDrive models), this Brembo GT Big Brake Kit for the rear is a serious consideration. This kit is designed to handle more heat and provide more stopping power, which is crucial for spirited driving or when carrying heavier loads. The larger 345x28mm two-piece rotors and the robust 4-piston calipers work together to offer a more consistent and powerful pedal feel compared to the stock setup.

This kit features Brembo's cast aluminum calipers, known for their strength and ability to dissipate heat effectively. The calipers are paired with two-piece rotors, where the rotor ring is separate from the hat. This design helps manage thermal expansion and can reduce weight compared to a single-piece rotor. The rotors themselves are slotted, which helps to clear out brake dust and gases that can build up between the pad and rotor surface, maintaining optimal friction and preventing glazing. The Type 3 slotting pattern is a popular choice for its balance of performance and rotor longevity. The calipers come finished in a striking red color, adding a visual upgrade to your wheels.

When installing a big brake kit like this, it's important to ensure you have the correct tools and follow the manufacturer's instructions carefully. While this kit is designed as a direct fit for the specified models, it's always a good idea to confirm compatibility with your specific wheel size, as the larger calipers and rotors may require more clearance. This kit is a substantial upgrade for the rear braking system, and it's often paired with a front big brake kit for a balanced braking system.
