Brembo 06-12 325i/328i (Excl. xDrive) Rr GT BBK 4Pist Cast 2pc 345x28 2pc Rotor Slotted Type1-Black

The rear rotors on this Brembo GT Big Brake Kit measure 345x28mm, a substantial increase over stock, designed to handle the heat generated during spirited driving. This kit is specifically for the rear of your 2006-2012 BMW 325i or 328i, excluding xDrive models. It features a 4-piston caliper and a 2-piece rotor construction, which helps manage thermal expansion and reduces unsprung weight compared to a single-piece rotor.

Brembo's GT Big Brake Kits are built for drivers who demand more from their braking system. The calipers are cast from aluminum for a good balance of strength and light weight, and they house four pistons that apply even pressure across the brake pad surface. This consistent pressure is key to achieving improved braking feel and fade resistance, especially when you're pushing your car hard. The rotors are slotted with Brembo's Type 1 pattern, which helps to vent gases and dust away from the pad surface, maintaining optimal friction and preventing glazing.

This kit includes everything you need to upgrade your rear brakes: the calipers, the 2-piece slotted rotors, brake lines, and mounting hardware. Proper installation is crucial for performance and safety, so we recommend referring to the manufacturer's detailed installation instructions. This is a significant upgrade for your BMW's braking system, offering a noticeable improvement in stopping performance and heat management.
