What is included with this Wilwood ST SX6R caliper?

This product listing is for a single Wilwood ST SX6R brake caliper. It includes the caliper body and internal components. You will need to purchase rotors, brake pads, and potentially other hardware separately to complete your brake system.

What are the benefits of a six-piston caliper with staggered piston sizes?

The staggered piston sizes (1.75", 1.38", and 1.25" in this case) help to distribute braking force evenly across the brake pad surface. This can lead to more consistent pad wear and improved overall braking performance under heavy use.

What other components are needed to install this caliper?

To properly install this caliper, you will typically need compatible brake rotors, high-performance brake pads, braided stainless steel brake lines, and high-temperature brake fluid. It's recommended to consult Wilwood's technical documentation or a professional installer for a complete list of required components for your specific application.

Product Details

What you get in this box is a single Wilwood ST SX6R brake caliper, designed for high-performance braking applications. This caliper features a unique six-piston arrangement with staggered piston sizes (1.75", 1.38", and 1.25") which helps to balance braking force and pad wear. It's built from forged aluminum, making it both strong and lightweight, which is crucial for reducing unsprung weight and improving overall vehicle dynamics. The SX6R is a popular choice for those looking to significantly upgrade their braking system beyond factory specifications.

The forged aluminum body offers a solid foundation for the caliper's internal components, ensuring consistent performance even under demanding conditions. Wilwood calipers are known for their robust construction and ability to handle the heat generated during aggressive braking. This particular model is engineered to work with specific brake pad shapes and rotor sizes, so it's important to ensure compatibility with your existing or planned brake setup. While this listing is for a single caliper, most vehicles will require two for the front axle, and potentially two more for the rear, depending on your build.

When planning your brake upgrade, remember that calipers are just one part of the system. You'll want to pair these with appropriate rotors, brake lines, and high-performance brake fluid to get the most out of this caliper. Wilwood offers a range of compatible components, and it's always a good idea to consult their technical resources or a knowledgeable installer to ensure all parts work together seamlessly for optimal braking performance and safety.
