Product Details
If you're looking to significantly improve the stopping power and feel of your 1984-1989 Porsche 911, this rear brake kit from Wilwood is a solid choice. This kit replaces your stock rear brakes with a more robust system designed to handle increased demands, whether you're driving spiritedly on the street or participating in track events. It includes everything you need to upgrade your rear braking performance, focusing on enhanced heat dissipation and consistent stopping power.
At the heart of this kit are the 11.42-inch drilled rotors. Drilling helps to vent gases and heat away from the rotor surface, which is crucial for preventing brake fade during heavy use. The calipers, finished in a bright yellow, are well-built and designed to provide strong clamping force. Wilwood is known for its performance brake components, and this kit reflects that reputation with durable materials and thoughtful engineering. The kit also comes with braided stainless steel flex lines, which are more resistant to expansion under pressure than rubber lines, leading to a firmer and more responsive pedal feel. This is a comprehensive upgrade that addresses key areas of brake performance.
When installing this kit, remember that it's a significant upgrade and may require careful attention to detail to ensure proper function. It's always recommended to consult the manufacturer's installation instructions for specific torque values and procedures. This kit is designed to be a direct fit for the specified Porsche 911 models, simplifying the installation process. You'll notice an improved pedal feel and more confident braking performance after installation.
