Product details
This red Dynalite kit supplies the 12.19-inch drilled-and-slotted rotor arrangement for the specified Wilwood ProSpindles. The front hubs, bearings and mounting hardware are part of the package, while flexline routing must be planned around the completed suspension and steering movement. Wilwood Engineering was established by Bill Wood in 1977 in the course of developing its disc brake business. Based in Camarillo, California, it designs and manufactures disc brake systems and components including master cylinders, valves, fittings, brake lines, calipers and brake rotors. Motorsport, street-performance and specialized applications each require a properly matched system.

Fitment & Compatibility
Check the ProSpindle number and height before ordering, then compare the complete brake template with the intended wheel. Caliper and steering-arm alignment follow separate instructions for the standard and dropped spindle versions. 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.
