What is the purpose of the staggered piston sizes in this caliper?

The staggered piston sizes (1.75-inch outer, 1.62-inch inner) are designed to create a more balanced application of force across the brake pad. This helps to ensure even pad wear and can contribute to improved pedal feel and stopping power.

What thickness of brake disc is this caliper designed for?

This Wilwood Aero6-R caliper is specifically designed to accommodate brake discs that are 1.25 inches thick. Using a disc of the incorrect thickness may affect caliper fitment and braking performance.

What other components are typically needed to install this caliper?

To complete a high-performance braking system, you will typically need matching brake rotors, brake pads, and brake lines. It's also important to ensure proper caliper mounting brackets are used, which may be vehicle-specific.

Product Details

When you're pushing your vehicle hard, especially on the track or during spirited driving, having reliable stopping power is crucial. The Wilwood Aero6-R caliper is built for those situations, offering a significant upgrade over stock braking components. This particular caliper is finished in a striking red, adding a visual performance element to your wheel setup.

This Aero6-R caliper features a robust six-piston design, with piston sizes of 1.75 inches for the outer pair and 1.62 inches for the inner four. This staggered piston arrangement is engineered to provide balanced braking force and improved pedal feel. It's designed to work with disc brakes that are 1.25 inches thick, allowing for substantial rotor mass to dissipate heat effectively. The caliper body itself is well-built from forged aluminum, which keeps weight down while maintaining structural rigidity under heavy load. This caliper is a key component for building a high-performance braking system that can handle demanding use.

For a complete braking system upgrade, this caliper is often paired with matching rotors, pads, and brake lines. Ensure you consult the Wilwood catalog or a braking specialist to confirm compatibility with your specific vehicle and desired rotor size. Proper installation and bleeding of the brake system are essential for optimal performance and safety.
