• Constructed from lightweight, high-strength aluminum alloy to reduce unsprung weight and improve vehicle handling.
• Exclusive triple bridge configuration enhances structural rigidity, delivering higher clamping force and improved torque capacity over traditional twin-bridge calipers.
• Single 1.75-inch bore piston designed for balanced braking force and smooth pedal modulation.
• Gray powder-coated finish provides corrosion resistance and a clean, professional appearance.
• Compatible with 12.190-inch outer diameter and 0.810-inch thick rotors, ensuring broad application versatility.
• 7.060-inch floating mount design allows for precise alignment and ease of installation on a variety of brake setups.
• Designed using solid modeling and stress simulation software to optimize strength-to-weight ratio and durability.
• High-temperature seals and dust boots ensure long service life and reliable operation under demanding conditions.

Construction & Design

The Wilwood D52-R caliper is crafted from billet aluminum, offering an excellent balance between strength and weight savings. The triple bridge design is a standout feature, providing enhanced torsional rigidity that minimizes caliper flex during heavy braking. This structural integrity translates directly into improved brake feel and consistent pad contact with the rotor.

Advanced CAD and finite element analysis were employed in the development process, allowing Wilwood engineers to refine the caliper’s geometry for optimal stress distribution. The gray powder coat finish not only protects the caliper from corrosion but also maintains a sleek, understated look that complements a wide range of vehicle styles.

Installation & Fitment

The D52-R caliper is designed for straightforward installation on compatible brake systems using the floating mount configuration. It fits rotors with a 12.190-inch outer diameter and 0.810-inch thickness, making it suitable for many performance and custom applications. The caliper mounts securely using existing hardware points, and no special modifications or tuning are required for proper fitment.
