Wilwood 84-89 Porsche 911 D31 11.42in. Rear Brake Kit w/ Flex Lines - Red

The D31 calipers in this rear brake kit are forged from aluminum, which keeps them lightweight while still being strong enough for demanding use. This kit is specifically built for the 1984-1989 Porsche 911 D31 models, offering an improved braking performance over the stock setup. You'll notice a more consistent pedal feel, especially during repeated hard stops, thanks to the larger rotor diameter and the advanced caliper design.

Wilwood engineered this kit to be a complete rear brake solution. It includes everything you need to upgrade your Porsche's braking system: the red D31 calipers, 11.42-inch rotors, and braided stainless steel flex lines. The rotors are vented, which helps dissipate heat more effectively, preventing brake fade when you push your car hard. The braided lines are a significant upgrade from rubber hoses, as they resist expansion under pressure, leading to a firmer and more responsive brake pedal. This combination of components works together to raise your car's overall braking capability.

When installing this kit, you'll be replacing your existing rear brake components. The flex lines connect the hard lines on your chassis to the calipers, and it's important to ensure they are routed correctly to avoid any rubbing or kinking. This kit is designed to be a direct fit for the specified Porsche 911 models, simplifying the installation process. You'll be getting a well-built system that not only performs better but also looks sharp behind your wheels.
