Application

The Aero4 brings race caliper technology into a body design with wide adaptability, delivering heavy-duty stopping power on the road or the track for heavier vehicles. This is a single caliper, not a pair, and it does not include pads, rotors or a mounting bracket.

Confirm caliper hand, rotor diameter and thickness, and mounting configuration before ordering.

About the Aero4

The Aero4 is the latest development of Wilwood's W4A and W6A caliper series, forged rather than cast for stiffness under load. Multiple piston volume options and a wide rotor diameter range let it be specified for heavy vehicles that need real thermal capacity, while radial mounting keeps bracket design straightforward.
