Brembo 01-06 M3 Rear GT BBK 4 Piston Cast 345x28 2pc Rotor Slotted TY3L - Silver

If you're looking to significantly improve the stopping power and feel of your 2001-2006 BMW M3, this Brembo GT Big Brake Kit for the rear is a serious upgrade. This kit is designed to handle the demands of spirited driving and track use, offering a substantial improvement over the factory braking system. It’s built around a robust 4-piston caliper and a large, two-piece rotor assembly that work together to dissipate heat and provide consistent, powerful braking.

The calipers in this kit are cast from durable aluminum, housing four pistons that apply even pressure across the brake pad surface. This ensures more uniform pad wear and a more direct pedal feel. The rotors are a substantial 345x28mm, constructed in two pieces with a cast iron friction ring bolted to an aluminum hat. This design helps reduce weight and allows for thermal expansion without warping. The friction rings are slotted, which helps to sweep away dust and gas that can build up between the pad and rotor, maintaining optimal braking performance even under heavy use. The silver finish on the calipers adds a clean, performance-oriented look to your M3's rear wheels.

This kit includes everything you need to get your M3's rear brakes upgraded to a high-performance standard. You'll find the calipers, the two-piece slotted rotors, brake pads, and all the necessary hardware for installation. While this is a bolt-on kit, it's a complex system, and we always recommend referring to the manufacturer's installation instructions for proper setup. Upgrading your rear brakes to this level is a critical step for any M3 owner prioritizing braking performance and safety.
