Info

Wilwoods GM Metric Caliper is a direct replacement for the 1978 and later D154 type GM metric caliper. Weighs starting at 2.92 pounds, it provides a substantial weight savings over cast iron OE calipers. This competition caliper represents that latest refinements in a caliper design and manufacturing through the use of comuputer based FEA solid modeling and stress simulation programs. The real strength of this caliper comes from its triple bridge configuration, and its lightness is a result of efficient design.

  • Casting using a tight grained, high density aircraft alloy
  • All load bering and stress points are fortified to maximize strength
  • All unnecessary material is removed to maximize weight reduction
  • Stainless pistons provide improved fluid protection with high resistance to corrosion and low heat transfer
  • Each is fully machined, assembled with a high temperature seals, and tested-in house at Wilwood
  • Completely interchangeable w/ stock GM caliper (racing only)
  • 11" to 13" diameter, 1.25" thick rotors
  • 3.7 lbs.
