Product details
Check the 5.08-inch mounting centers before fitting this anodized Wilwood Powerlite-ST brake caliper. The component is sold individually and uses 1.25/1.25-inch bores in its 0.50-inch rotor-width configuration. Powerlite-ST uses a compact radial-mount body with Thermlock insulated pistons and top-supported 7912-shape pads. The bore size must be selected with the master cylinder and hydraulic balance; nominal rotor width is independent of rotor diameter and wheel diameter. Bill Wood established Wilwood Engineering in 1977. From Camarillo, California, the company designs and manufactures calipers, rotors, master cylinders, valves, fittings and brake lines as part of its disc brake range. Its motorsport, street-performance and specialized products are chosen around the requirements of the whole braking system.

Fitment & Compatibility
Compare the caliper drawing with your radial bracket before ordering. The 5.08-inch mounting centers and 1.25/1.25-inch bores must suit the installed rotor offset and hydraulic system. Axle placement is determined by the engineered brake package, not by a generic caliper designation. A suitable pad sweep and clearance inside the wheel must be verified independently of rotor width.
