The Brembo rear big brake kit for Ferrari Testarossa models produced 1984–1987 pairs four-piston billet calipers with 380×28 mm two-piece slotted rotors finished in nickel plating. As a rear upgrade, the Type 1 slotted rotor pattern is intended to aid pad bite and keep surfaces cleaner under load, delivering a more secure feel compared with original rear braking components.
