The Wilwood Aero4-DS caliper packages race-derived stopping power with an environmental dust-wiper seal to protect the piston bore. Built for road or track use, it supports rotor diameters similar to the Aero family and offers radial mounting and piston-volume choices for adaptable brake setups. The dust wiper seal helps resist contamination, extending service life where environmental sealing is required.
