Product Details
This Wilwood brake kit for your 1969-1983 Porsche 911 includes everything you need to upgrade the rear braking system. You get a pair of D31 DUAL-SLOT calipers finished in a bright yellow, a pair of 11.42-inch diameter drilled rotors, caliper mounting brackets, and stainless steel braided flexlines. This kit is designed to give your classic 911 a significant boost in stopping power and thermal capacity, crucial for spirited driving or track use.
The D31 calipers are a well-built, two-piston design that offers a good balance of clamping force and pad volume, allowing for consistent performance. The rotors are drilled, which helps to dissipate heat and expel gases and moisture from the pad surface, leading to more reliable braking, especially under heavy use. Wilwood's reputation for performance braking components means you're getting parts designed to handle the demands of a performance vehicle like the Porsche 911. The included stainless steel braided flexlines are a key upgrade over rubber lines, as they resist expansion under pressure, providing a firmer pedal feel and more direct brake response.
Installing this kit will require some mechanical knowledge, as it involves replacing your existing rear brake components. It's always a good idea to consult the manufacturer's installation instructions for specific details and torque specifications. Upgrading your brakes is a critical step for any performance vehicle, and this Wilwood kit offers a comprehensive solution for the rear of your 911.
