The Brembo GT rear big brake kit for 2005–2013 Range Rover Sport (L320) replaces the rear hardware with a four-piston cast caliper and a 380×28mm two-piece drilled rotor finished in black. It’s specified to provide a larger, multi-piston braking setup for heavier applications and improved control. Included rotor and caliper specifications match the listed Range Rover Sport L320 fitment for those years.
