Caliper Highlights:
Wilwood’s GM III caliper represents the latest
refinements in caliper design and manufacturing
through use of solid modeling and stress
simulation programs. The result is the most
rigid, highest torque, lightweight aluminum
caliper in its class.
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, resulting
in a caliper that weighs just over three pounds.
The GM III incorporates standard Wilwood features like stainless steel pistons for increased fluid protection and high
temperature seals for controlled retraction which provides improved driver feel.
These tight grained, high density aircraft alloy aluminum castings are fully machined, assembled and tested in-house
by fully trained technicians at Wilwood to assure top quality and peak performance.
