Product details
Check the 7.06-inch mounting centers before fitting this anodized Wilwood D52-R brake caliper. The component is sold individually and uses 2.75-inch bore in its 1.04-inch rotor-width configuration. 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. The Wilwood disc brake range is designed and manufactured for motorsport, street-performance and specialized applications. It includes brake lines, fittings, valves and master cylinders together with calipers and brake rotors. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California; its components must be matched to the complete braking 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.
