Brembo 01-06 M3 (E46) Front GT BBK 4 Piston Cast 2pc 355x32 2pc Rotor Drilled-Silver

This Brembo GT Big Brake Kit for the 2001-2006 BMW M3 (E46) includes everything you need to significantly upgrade your front braking system. You'll get a pair of Brembo's 4-piston GT calipers, two-piece 355x32mm rotors that are drilled for improved heat dissipation, and all the necessary hardware for installation. This kit is designed to replace your factory front brakes with a much more robust setup, offering improved stopping power and fade resistance for spirited driving and track use.

The calipers are cast from aluminum for a good balance of strength and light weight, and they feature a 4-piston design. This means more clamping force is applied to the rotor surface compared to a typical 2-piston caliper, leading to quicker stops. The two-piece rotor construction is notable because it allows the rotor and the hat to expand and contract independently with heat. This helps prevent rotor warping and cracking over time, especially under heavy braking. The drilled surface on the rotors helps to vent gases and heat away from the pad surface, maintaining consistent performance even when the brakes get hot. The silver finish on the calipers and the drilled rotors gives your M3 a distinct, performance-oriented look behind the wheels.

Installing a big brake kit like this is a significant upgrade, and it's often done when rebuilding the braking system or when preparing the car for track days. While this kit is designed as a direct replacement for the factory brake components on the E46 M3, it's always a good idea to consult the manufacturer's installation guide for specific details and torque specifications. You may also want to consider upgrading your brake fluid to a higher temperature rating to take full advantage of the kit's capabilities.
