Product details
Red AERO6 calipers and 14-inch drilled/slotted rotor rings identify this later-GM front big-brake configuration. It supplies BP-10 pads, separate hats and five-lug aluminum hubs, all intended for the documented iron ProSpindle interface. Check the actual Wilwood spindle rather than assuming any lowered spindle will accept the brackets. The complete wheel contact surface and caliper clearance must also be verified. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. It designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. This kit is one configuration within that disc-brake-system range and must be matched to the vehicle build.

Fitment & Compatibility
The listed later GM truck, van and SUV applications require the matching Wilwood C10 one-piece iron Pro Drop spindles. Original equipment spindles will not fit. The table has distinct 1988–1998 pickup entries and later SUV/van ranges, with certain van applications extending to 2002; do not apply one overall span to every model. Confirm the correct spindle generation, five-lug wheel interface, full hub seating and clearance around the caliper. Flexible brake lines are ordered separately for the vehicle being built. Use the complete application table below for the individual year, submodel, brake configuration and note attached to each entry.
For fitment assistance, send PMB Performance the vehicle details together with the installed spindle or axle configuration and wheel measurements. We draw on 20+ years of parts and fitment experience to help assess the combination.
