The cast aluminum GT III Caliper is ideal for NASCAR Nextel Cup, Busch GN, Craftsman Truck, ARCA Supercars and SCCA road racing. The double bridge bolt design is extremely rigid and provides drivers with a firm, responsive pedal and superior stopping power. The differential piston bores have been positioned to maximize clamping force, provide even pad wear and enhance caliper stiffness. Weighing only 8.4 pounds, the GT III incorporates stainless steel heat shielding throughout the bridge area and piston bore facing, along with heavy duty pad abutment plates. The GT III utilizes the thick GT pad (11.3 cubic inches, 1.10” thick), and is a direct bolt-on interchange with the 5.25” mount GT Series calipers.

Wilwood’s exclusive short track pistons are available for the GT III Caliper. Recirculator tubes are also available.
