Brembo 01-06 M3 Rear GTS BBK 4 Piston Cast 345x28 2pc Rotor Slotted TY3L - Black HA

The cast iron caliper housing on this Brembo rear brake kit is built to handle the heat generated during aggressive driving. This kit is specifically designed for the 2001-2006 BMW M3, offering a significant upgrade over the factory braking system. It features a 4-piston caliper design, a 345x28mm two-piece rotor with a slotted surface, and a black finish for a clean look.

This GTS Big Brake Kit (BBK) is engineered for performance, with the 4-piston calipers providing increased clamping force for more consistent stopping power. The two-piece rotor design helps manage heat and reduce unsprung weight, while the slotted surface helps to clear out brake dust and gases, maintaining optimal pad contact. The cast iron construction of the caliper is chosen for its durability and ability to withstand high temperatures, crucial for track or spirited driving conditions. This kit is a substantial upgrade for M3 owners looking to improve their vehicle's braking performance and feel.

When installing this kit, ensure you have the necessary tools and refer to the manufacturer's installation instructions for proper fitment and procedure. This is a comprehensive rear brake upgrade, and while it is designed as a direct fit for the specified M3 models, professional installation is recommended to ensure optimal performance and safety.
