Details

When it comes to brake rotors, racers are constantly searching for the ultimate balance between the lowest weight and the ability to effectively manage heat. Decreased rotating weight in the drive line provides quicker deceleration under braking and quicker acceleration out of the corners. Lower weight also benefits handling with improved spring and shock control over the unsprung suspension mass. Wilwoods ULD-32 drilled iron rotors provides effective lightweight options for sprints, late models, modifieds, and other competition applications that race in low to medium temperature ranges.

  • Cast from premium grade, long grain carbon iron
  • Close tolerances on face and vane thickness
  • 32 straight vane casting provides superior heat management and long service life
  • Two row, 64 hole pattern - alternates between and directly over each vane
  • Each hole deeply chamfered to eliminate stress points
  • Rotating and unsprung rotor mass reduced by 12%
  • Left or right hand mounting locations
