Description

Wilwood AERO4-DS radial mount calipers deliver heavy-duty stopping power for the road or track. These forged 4-piston calipers incorporate race technology into a body design with widespread adaptability, and they feature the latest innovation to the Aero Series—a dust wiper seal (DS) that further protects the piston bore from dust and corrosion. With radial mounting, multiple options for piston volume, and a rotor diameter ranging from 12.88 in. to 15.00 in., Wilwood AERO4-DS calipers are ideal additions for greater braking performance.
