Description

Wilwood D31 rear brake kits utilize forged aluminum D31 direct-mount calipers to provide the ultimate in strength, weight savings, and high efficiency brake clamping for Porsche 911 cars with "M" 3 in. OEM rear calipers. D31 calipers feature high-strength, lightweight 4.1 lb. forged aluminum bodies fitted with machined stainless steel pistons, and utilize the same 3 in. mounting centers, height, and offset as the traditional 911 "M" calipers.

Wilwood D31 rear brake kits contain D31 calipers available in several powdercoated colors, standard D31 brake pads in BP-10 compound, OEM replacement 11.42 in. diameter rotors available in two thicknesses in either a plain face surface or an SRP directional drilled and slotted configuration with a black E-coat finish, and DOT-compliant stainless braided brake hoses. Select the color and rotor style preferred for your Porsche.
