LH and RH 1978-Up Metric Brake Calipers

These stock replacement single-piston Metric calipers were standard equipment on 1978-88 GM mid-size cars (Cutlass, Grand Prix, Regals, Monte Carlo, etc.). They feature a 2.375" single piston, shielded bottom inlet, and will save 3-1/2 lbs. per side compared to mid-size 1969-1977 caliper.

  • 7/16"-20 inlet
  • 5-1/2" Mount Spacing
  • Can be used with brake hoses from Pre-1978 GM intermediate cars

Speedway Pro-Lite Vented Brake Rotors, 11.75 x .81 Inch

Every rotor is cast from premium grade, long grain carbon iron which exhibits long wear, high thermal stability, and excellent resistance to distortion in high heat. Modern foundry and machining techniques hold close tolerances on face and vane thickness. Combining the correct face thickness with a 32 vane casting provides superior heat management and long service life with low rotating and unsprung weight. The straight vane design also makes it possible to use the same rotor on left or right hand mounting locations.

  • Thickness: GM .810"
  • Outside Diameter: 11.75"
  • # Holes: 8
  • Bolt Circle: 7"
  • Thread: Thru
  • Weight: 8.00 lbs
