The Wilwood Aero4 four-piston caliper in red finish is a compact, forged unit designed for heavy-duty stopping with improved internal fluid routing to eliminate external cross-over tubes. Radial mounting and piston-volume options provide installation flexibility, and the caliper supports a broad rotor diameter span to suit diverse street and track braking needs where consistent clamping and packaging simplicity matter.
