Product Details
Wilwood is well-known for making serious braking components for performance vehicles. This Dynapro Lug Mount Single Rear Dynamic Kit is a prime example, designed to handle the extra heat generated by rear brakes on cars that rely heavily on them for stopping, or any high-speed, heavy vehicle that pushes rear brake temperatures beyond normal limits. The unique lug-drive rotor mounting system is a key feature here. Instead of traditional rotor bolts, a single internal snap-ring holds the rotor to the hat. This setup allows the rotor to expand and contract freely with heat cycles, preventing thermally generated stress at the attachment points. This means your rotors stay flatter and run truer, improving consistent braking performance over time.
The hats are also protected from the stresses of rotor expansion and contraction. Wilwood includes spring-loaded, replaceable stainless steel inserts in each lug-drive slot. These inserts act as a buffer, protecting the aluminum hat from wear that could occur when the stainless steel rotor torques against it during braking. This kit comes with an 11.44-inch diameter rotor, a traditional size that offers excellent stopping power. This kit is configured for single caliper use, and the .690-inch studs are part of the specific setup for Lamb/MW ends.
When you're working on a vehicle that demands more from its rear brakes, especially under demanding conditions, this kit offers a robust solution. The independent movement of the rotor and hat, along with the hat protection inserts, contributes to a more stable and durable braking system that's built to last. Ensure you consult the manufacturer's installation instructions for specific details regarding assembly and fitment for your application.
