Description
The Wilwood Narrow Superlite 6R Front Brake Kit (part number 140-10284-D) is configured with Black Calipers. Application: 1957-1970 GM.
The radial-mount caliper arrangement uses a dedicated bracket to establish caliper position over the rotor. Bracket geometry and rotor offset are therefore part of the fitment specification. The rotor configuration and caliper finish shown here identify this specific part number. Match the required axle, spindle, mounting arrangement, and any listed offset to the vehicle’s installed components.
