Wilwood Dynapro Lug Mount Dual Rear Dynamic Kit SA Drilled 58-64 Olds/Pont .690in Studs

The Wilwood Dynapro Lug-Drive Dynamic Brake Kit uses a unique lug-drive rotor mounting system, which replaces traditional rotor bolts with a single internal snap-ring. This design allows the stainless steel rotors 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, which is especially beneficial for cars that rely heavily on rear brakes for stopping, or any heavy vehicle that generates significant rear brake heat.

Each lug-drive slot features spring-loaded, replaceable stainless steel inserts. These inserts protect the aluminum hat from wear caused by the rotor pressing against it under braking torque. This kit is configured for dual caliper setups and includes rotors with drilled surfaces for improved heat dissipation. The .690 inch studs and 2.81 inch offset are specific to the 1958-1964 Oldsmobile and Pontiac applications this kit is designed for.

This kit is a substantial upgrade for vehicles where rear brake performance is critical. The advanced rotor mounting and caliper configuration work together to ensure consistent stopping power and longevity, even under demanding conditions. Ensure you consult the manufacturer's installation instructions for proper assembly and setup.
