The Brembo GT big brake kit for 2009–2015 7-Series front applications features 6-piston cast calipers matched to 405×34 mm two-piece drilled rotors in black. Specified as a front upgrade, the six-piston cast calipers enhance clamping distribution while drilled two-piece rotors help release gases and heat during repeated heavy braking. The design balances stopping power with rotor serviceability.
