Product details
Select this anodized Wilwood D52-R brake caliper by the actual floating mounting geometry, not just its appearance. The 1-piston unit uses 2.38-inch bore dimensions and is configured around a 0.81-inch-wide rotor. The D52-R is a single-piston floating race caliper using the D52 pad outline and stock-height mounting geometry. Slide pins and vibration dampeners are not supplied. Match the racing rules and the complete sliding support before installation. Wilwood Engineering, founded in 1977 by Bill Wood, is based in Camarillo, California. The company designs and manufactures disc braking equipment for motorsport, street-performance and specialized use. Calipers, rotors, master cylinders, valves, fittings and brake lines form a range whose individual components must be matched to one another.

Fitment & Compatibility
Match the 7.06-inch floating attachment to the existing bracket, then check caliper centering over the 0.81-inch nominal-width rotor. Axle placement is determined by the engineered brake package, not by a generic caliper designation. The 7/16-20 connection must use the correct fitting and seal. Check the full wheel envelope with the actual bracket and rotor installed.
