GM III Single Piston Floater
Wilwood’s GMIII caliper represents the latest refinements in caliper design and manufacturing through solid modeling and stress simulation programs. The result is the most rigid, highest torque, lightweight aluminum caliper with weights starting at 3.36 pounds. 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  

The real strength comes from its exclusive triple bridge configuration which provides a tremendous increase in clamping force over other twin bridge calipers. Efficient­ designs further maximize weight savings: material is properly placed to fortify all load bearing points. Each caliper model has its own unique casting: 2.38” diameter piston calipers incorporate a smaller external contour than the larger 2.75” diameter piston calipers. Any material that did not contribute to strength, was eliminated for weight reduction.   Continue >>
