Model 248, 250, 275, and 330 Ferraris use a "spread flange" cylinder housing on the front calipers. Oversized piston units are listed in italics. These units will provide approximately 10-15% greater force on the brake rotor, decreasing the required brake pedal pressure during braking, and potentially shortening stopping distances.
