Wilwood Front D623 Inner and Outer Brake Pads in BP10 Compound

The D623 set contains different inner and outer pad forms, with 0.68-inch and 0.63-inch listed thicknesses respectively. BP10 provides the same friction choice across the set, while correct positioning depends on matching the two plate designs to the caliper. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. The company designs and manufactures disc brake systems, with calipers and brake rotors complemented by master cylinders, valves, fittings and brake lines. That range supports specialized applications as well as motorsport and street-performance vehicles; the entire brake system determines component selection.

Fitment & Compatibility

Wilwood’s D623 drawing identifies this as a front-pad profile with different inner and outer plates. Verify the 0.68-inch inner and 0.63-inch outer dimensions, the plate widths and retention against the actual front caliper. The drawing’s GM heading does not establish blanket model or year coverage.

For a street-oriented system, BP10 provides progressive engagement on iron or steel rotor faces. Wilwood also recommends it for muscle cars, drag racing and light-to-medium dirt competition. Rotor material and expected braking temperature should govern compound selection; a pad that fits mechanically is not automatically right for every track session.
