Product details
The polished calipers distinguish this 12.19-inch Dynalite front-brake package for Wilwood ProSpindles. SRP rotor faces are drilled and slotted, and the included hub components need to be assembled with the correct stud pattern and spindle-specific bracket layout. Street-performance cars, motorsport vehicles and specialized applications are served by Wilwood Engineering’s disc brake systems. Founded by Bill Wood in 1977 and based in Camarillo, California, the company designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines. Correct selection starts with the complete brake system.

Fitment & Compatibility
If the wheel center overhangs the hub face, Wilwood requires the separate 6.60-inch-diameter x 0.20-inch steel spacer 300-11961. For stamped-steel wheels that do not overhang the hub, the instructions recommend the 6.15-inch x 0.09-inch hub shield 300-10716. Verify wheel support, lug engagement and the complete wheel-clearance template. OE rubber hoses do not adapt directly; fit correctly routed, compatible braided flexlines.
Use only the supported ProSpindle arrangement and follow the height-specific bracket procedure. The kit does not establish vehicle fit from a chassis name alone, and the actual wheel must clear the rotor, caliper and hub assembly. Compatible spindle part numbers are 830-10832 for standard height and 830-9807 for the two-inch drop. The published +0.10-inch hub offset is per side and must be included in the wheel/fender clearance assessment.
