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

The Wilwood Dynapro Lug Mount Single Rear 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 from distorting the rotor 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 generate significant rear brake heat.

This kit features 11.44-inch diameter SA Drilled rotors, designed to handle high speeds and heavy loads. The lug-drive system also incorporates spring-loaded, replaceable stainless steel inserts within each lug-drive slot. These inserts protect the aluminum hat from wear caused by the rotor's interaction with the hat during braking torque application. The .690-inch studs and 2.81-inch offset are specific to fitment for 1958-1964 Oldsmobile and Pontiac models, ensuring a proper installation for these classic vehicles.

This rear brake kit is a comprehensive solution for improving your classic car's stopping power. It's designed to manage the heat generated by hard braking, ensuring consistent performance. Ensure you consult the manufacturer's installation instructions for specific details regarding assembly and mounting to your vehicle.
