GN III and GN III/ST Caliper Features:
High strength, low deflection, and superior stopping power. Each GN III is manufactured from a precision casting using a tight grained, high-density aircraft alloy. It is a two piece, closed bridge design with grade 8 thru-bolts and external stiffening ribs. The GN III utilizes a unique six-piston configuration that generates high clamping force with balanced loading for extremely even pad wear. The 1.75" / 1.38" / 1.38" bore pattern contains a total of 5.44 square inches of effective piston clamp area. This makes the GN III one of the largest calipers available. The caliper bridges are fitted with stainless steel plates to reduce wear and provide smooth pad operation. Dual center bridge bolts add to the overall caliper strength and provide positive retention for the top loaded pads. Dollar for dollar, this combination is unmatched for high strength, low deflection, and superior stopping power.

 
GNX4 calipers are the product of Wilwood’s in-house FEA design and 3-D modeling technology. With its unyielding strength and superior piston design, the GNX4 generates positive pedal response and high clamping efficiency with a substantial weight savings over comparable OE Calipers. Base model calipers feature a natural aluminum finish protected by a durable clear coat anodizing. Forged billet aluminum bodies, stainless steel pistons, and high-temperature seals put an end to the rust, bore pitting, and seal failures that plague many OE caliper design.
 
The GP 320 billet caliper has been FEA developed and fully CNC machined. This yields the highest possible clamping efficiency without deflection while providing balanced pad loading, all from a compact, lightweight four piston design. Corrosion free 1.25" diameter stainless pistons resist heat transfer from the pads to reduce thermal distortion in the piston bores, extend seal life, and reduce fluid temperatures to help prevent heat generated pedal fade. Quick-Clip pad retainers allow fast service of the top loaded pads 3.50" centered mount is easily adapted to common brackets provided by the spindle manufacturers. PolyMatrix “H” compound brake pads compliment this caliper and have a smooth, predictable engagement at all temperatures with continued positive response as pedal pressure is increased or brake temperatures rise. These pads yield a long wear rate and are fade resistance to over 1,300° F.
