Product details
This red Wilwood XRS6R uses a 1.62-inch piston followed by two 1.12-inch bores on each opposing bank. The right-hand caliper is selected for its 4.04-square-inch effective area and 1.10-inch nominal rotor-width specification, not simply the number of pistons. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems for motorsport, street-performance and specialized use, including calipers, brake rotors, master cylinders, valves, fittings and brake lines.

Fitment & Compatibility
The matching bracket must center the housing over a rotor within the listed diameter limits. Keep the differential-piston orientation correct when choosing a mounting location ahead of or behind the spindle.
