Red Superlite 6R calipers clamp 12.88-inch GT slotted rotors in this Wilwood front hub package. The separate hats and aluminum hubs suit the early Ford/Mercury factory disc-spindle geometry. This arrangement includes a +0.25-inch mounting offset change that matters when evaluating the existing wheels and fender clearance.

The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Use the exact model/year and spindle option from the table, especially the Mustang production distinction at 1970. Inspect the bearing and steering-knuckle arrangement against DS590 before assembly. Hydraulic hoses are not supplied. Check the wheel's complete inner shape, and evaluate the existing master-cylinder displacement and pushrod travel as part of the whole brake system.

Match the individual model, year, submodel and brake configuration in the fitment table below.
