Wilwood's front medium-duty disc brake kits are designed for cars weighing up to 2,800 lbs., and are compatible with either disc or drum rear brakes. These kits combine the powerful clamping force of Dynalite aluminum calipers with the added performance and cooling capacity of competition-style, vented, iron-alloy rotors. Other features include aluminum-alloy brake hats, Polymatrix "T" compound brake pads, aluminum caliper brackets, Grade 8 mounting hardware, and detailed instructions for an easy bolt-on installation.
