The Wilwood Aero4 forged four-piston caliper combines race technology and adaptable design for heavy-duty braking on road or track. Radial-mount configuration, multiple piston-volume choices and support for 12.88"–15.00" rotor diameters make it broadly applicable. Redesigned internal fluid ports eliminate external crossover tubes and simplify the central structure, keeping installation and maintenance straightforward.
