The Brembo rear big brake kit for 2006–2010 BMW M5 and M6 fits the rear axle with four-piston billet calipers and 380 x 28 mm two-piece drilled rotors in a nickel finish. Presented as a rear GTR BBK, this kit upgrades factory rear components to larger calipers and two-piece rotors to enhance heat dissipation and maintain pad engagement, offered as a direct rear replacement for those M5 and M6 years.
