The Brembo GT big brake kit for 2001–2006 BMW M3 (E46) is a front four-piston package that pairs cast two-piece calipers with 355 x 32 mm two-piece slotted Type‑3 rotors in red. Offered as a vehicle-specific front upgrade, this kit replaces stock hardware to deliver larger rotors and four-piston calipers for improved braking consistency and enhanced rotor cooling under repeated use.
