The Wilwood D31 rear dual-piston caliper specified for a 0.94" rotor is offered in an anodized finish and intended for rear applications requiring that rotor profile. The dual-piston configuration provides even clamping across the pad contact area, and the anodized surface helps resist corrosion. It’s supplied as a direct-replacement rear caliper where 0.94" rotor compatibility is needed.
