The Brembo Big Brake Kit is a front brake upgrade for 2008–2013 BMW M3 and 2011–2012 1M applications, combining six‑piston cast calipers with 365 x 34 mm two‑piece slotted rotors. Finished in black, the GT setup increases piston area and rotor capacity to help resist fade and sharpen pedal response for street and occasional track use when matched to the specified vehicles.
