Product details
Drilled-and-slotted 12.19-inch rotors pair with black four-piston calipers in this larger ProSpindle conversion. Aluminum hubs and rotor-mounting hardware must be used with the documented spindle geometry. The manufacturer, Wilwood Engineering, was established by Bill Wood in 1977 and is based in Camarillo, California. It designs and builds disc brake systems with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Motorsport, street-performance and specialized applications require components selected for the complete braking system.

Fitment & Compatibility
Check DS1014 against the installed ProSpindle and bearing arrangement. The wheel must seat fully on the hub face and clear the caliper after accounting for the listed wheel-position change.
The matching ProSpindles are the separately purchased standard-height 830-10832 or 2-inch-drop 830-9807. Follow the installation steps specific to the selected spindle.
Support the entire wheel mounting pad. An overhanging contact surface calls for 300-11961, the 6.60-inch x 0.20-inch steel spacer (sold separately). For a stamped steel wheel that stays within the hub face, the manufacturer recommends separate shield 300-10716: 6.15-inch diameter and 0.09-inch thickness.
Flexible brake lines are not included. Original lines are not assumed to connect to the Wilwood calipers; select the application-specific or correctly sized universal hose and matching fittings.
