Product details
The Wilwood Pantera hat uses an 8 x 7.62-inch through-hole rotor interface. Check the 1.380-inch offset and 3.23-inch center register. Bill Wood’s 1977 founding of Wilwood Engineering began a disc brake design and manufacturing business based in Camarillo, California. The range includes master cylinders, calipers, rotors, brake lines, valves and fittings for motorsport, street-performance and specialized vehicles. Component selection must consider the complete braking arrangement.

Fitment & Compatibility
For De Tomaso Pantera brake conversions, compare the replacement with the actual hat and complete brake-kit instructions. A matching flange pattern alone does not establish rotor alignment or caliper clearance. Select the rotor and attachment hardware separately for the documented assembly. Follow the installation drawing for engagement and clearance at every mounting point.
