GM-Metric Single Piston Floater
Wilwood’s GM Metric Caliper is a direct replacement for the 1978 and later D154 type GM metric caliper. Weights starting at 2.92 pounds, it provides a substantial weight savings over cast iron OE calipers. Requires use of hardened Wilwood slide pins (sold separately), request part no. 230-0619 (slide pin kit) contains 4 slide pins, enough for two calipers  

This competition caliper represents the latest refinements in caliper design and manufacturing through the use of computer 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.   Continue >>
