Brembo - The Gran Turismo Brake Systems are comprised of both 1 or 2-piece vented rotors that are 12 to 15 inches cross-drilled or slotted. In the 2-piece system, billet aluminum hats are application specific and have been individually machined to engineering specifications. The marriage of these pieces create a "floating disc" which reduces heat related stress and improves brake performance and pedal feel.
