Product details
Red four-piston Dynalite calipers and 11-inch drilled-and-slotted rotors form this ProSpindle front hub package. It supplies a complete pair of service-brake assemblies, but requires compatible spindles, separate flexlines and a wheel that clears the assembled brake profile. Disc brake system design and manufacturing are Wilwood Engineering’s focus. The company was founded by Bill Wood in 1977 and is based in Camarillo, California; its motorsport, street-performance and specialized product range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines. The mating components matter as much as the individual part.

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.
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.
