Brembo - The 1H4.8002A Gran Turismo Brake Systems are comprised of 1-piece vented and cross-drilled rotors 355mm in diameter. Installation requires minor cleaning up of the casting flashing on the lower control arm and some filing to clearance the mounting bracket on the spindle assembly. A simple coarse file for aluminum is sufficient for this modification. Performance Street pads and Competition pads available for these systems.
