Product details
This black-caliper front kit combines 12.19-inch SRP drilled-and-slotted rotors with the ProSpindle hub assembly. Its Dynalite four-piston calipers use BP10 pads, while the vehicle's spindle choice and wheel dimensions determine installation suitability. Wilwood Engineering has designed and manufactured disc brake systems since Bill Wood founded it in 1977. The company is based in Camarillo, California, and covers motorsport, street-performance and specialized applications. Its product range—calipers, brake rotors, master cylinders, valves, fittings and brake lines—must be matched to the complete installation.

Fitment & Compatibility
This is a Wilwood ProSpindle brake assembly. The standard-height and two-inch-drop versions use different mounting instructions, so the spindle and steering-arm hardware should be identified before the hub and caliper are assembled. 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.
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.
