Heavy-duty Wilwood Dynalite Pro series rear disc brake kits are designed for vehicles with Detroit "musclecar" rear axles, without rear-mounted parking brakes. They can provide absolute braking performance for a wide variety of street, custom, show, and race cars. They combine the powerful clamping force of the new-generation, forged-billet, 4-piston Dynalite calipers with the added performance and cooling capacity of competition-style vented and slotted iron-alloy rotors. Other features include aluminum-alloy brake hats, Polymatrix brake pads, aluminum caliper brackets, Grade 8 mounting hardware, and detailed instructions for an easy, bolt-on installation.
