Wilwood 140-10742-DR Details

DynaPro 6 forged billet calipers are combined with 12.19" diameter rotors for this group of traditional non-ABS spindles on American muscle cars and vintage rods. The enhanced brake capacity and pad performance of the six piston calipers provide an intermediate level alternative to the bigger six piston kits. These kits compliment wheel, tire, and suspension upgrades on all types of custom show and high performance street / strip machines. A full range of caliper finishes and rotor designs enable the builder to personalize the style and optimize the brake performance for each individual application.
