D31 Rear Brake Kit

Wilwood’s D31 Rear Brake Kits utilizing our forged aluminum D31 direct mount calipers provide the ultimate in strength, weight savings, and high efficiency brake clamping for Porsche 911 with "M" 3.00" OEM rear calipers. These calipers feature a high strength, lightweight 4.1-pound forged aluminum body fitted with machined stainless-steel pistons. D31 series calipers utilize the same 3.00" mounting centers, height and offset as the traditional 911 "M" calipers and contain standard D31 brake pads in BP-10 compound, OEM replacement 11.42” diameter and 0.79” or 0.95" thickness rotors in either a plain face surface or an SRP directional drilled and slotted configuration with a black e-coat finish. D31 calipers are offered in Black and Red powder coat finishes and can be also special ordered with yellow powder coat, Type III hard anodize or any of the special powder coat colors available at an extra charge. Kits include DOT compliant stainless braided brake hoses.
