Wilwood D31 Rear Dual Piston Caliper (0.94 Rotor) - Yellow

The caliper body on this Wilwood D31 rear caliper is forged from aluminum, which keeps the overall weight down while still offering a solid foundation for the dual pistons. This particular model is set up to work with rotors that are 0.94 inches thick, making it a specific choice for certain rear brake setups where you're looking to upgrade from a single-piston design.

Wilwood is known for making well-built brake components, and this caliper is no exception. The dual pistons help distribute clamping force more evenly across the brake pad, which can lead to improved stopping performance and more consistent pad wear compared to a single-piston caliper. The yellow finish isn't just for looks; it's a durable coating that can help protect the aluminum body from corrosion and road grime, keeping your brake system looking sharp.

When considering a rear caliper upgrade like this, it's important to ensure it matches your rotor size and that your master cylinder can adequately supply the fluid volume and pressure needed for dual pistons. This caliper is a solid option if you're building a custom rear brake system or replacing worn-out components with something that offers a step up in performance.
