Product details
The 5.08-inch radial pattern identifies the attachment layout of this Wilwood Powerlite 2R. This right-hand nickel-plated caliper has 2 pistons, 1.75-inch bores and a 0.50-inch nominal rotor-width specification. Wilwood Engineering’s disc brake range includes calipers, rotors, master cylinders, valves, fittings and brake lines. Bill Wood founded the company in 1977 in California; it is based in Camarillo and serves motorsport, street-performance and specialized brake applications.
The two-piston Powerlite 2R is intended for compact competition brake packages, including formula and open-wheel layouts. Thermlock pistons and top-loading type 7912 pads are paired with a 5.08-inch radial mounting pattern.

Fitment & Compatibility
Measure the available space at both sides of the rotor, including its hat. Confirm mounting geometry and piston area; rotor width by itself cannot establish a complete brake package.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
With over 20 years of experience, PMB Performance can help compare piston configuration and mounting geometry. Share the existing brake package and measured rotor dimensions before ordering.
