Product details
Plain-face 12.19-inch rotors are matched with red Forged Dynalite calipers in this front hub kit. It is built for the supported Wilwood ProSpindles, with the caliper brackets and steering-arm hardware assembled according to the selected spindle height. The brake-system manufacturer Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. It designs and manufactures disc brake systems, covering motorsport, street-performance and specialized needs with calipers, brake rotors, master cylinders, valves, fittings and brake lines. Component compatibility must be assessed across the whole installation.

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.
The installed ProSpindle governs the mounting procedure. Verify its height, steering-arm orientation and available wheel space; the supplied dual-pattern hubs do not make this a universal front brake conversion. 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.
