Product details
The anodized Wilwood D52-R is an individual brake caliper. It combines a 7.06-inch attachment span with 2.75-inch piston bore; confirm the rotor centerline and 1.28-inch width configuration before installation. 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. Based in Camarillo, California, Wilwood Engineering has its origins in the company Bill Wood founded in 1977. Its designs and manufactured disc brake products cover calipers and rotors alongside master cylinders, valves, fittings and lines. Motorsport, street-performance and specialized installations each require components selected for the complete system.

Fitment & Compatibility
Compare the caliper drawing with your floating bracket before ordering. The 7.06-inch mounting centers and 2.75-inch bore 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.
