Product Details

Wilwood is well-known for making serious braking components for both the street and the track. This Aero4 forged four-piston caliper is a prime example, built to handle heavy-duty stopping demands. It takes race-proven technology and puts it into a body design that's adaptable to a wide range of applications. Whether you're building a street car that sees occasional track days or a dedicated race vehicle, this caliper offers the stopping power you need.

This caliper is designed for radial mounting and can accommodate rotor diameters from 12.88 inches up to 15.00 inches, giving you a lot of flexibility. It features staggered piston sizes, with one piston measuring 1.88 inches and the other 1.62 inches, which helps to balance braking force. The latest innovation in the Aero4 design is the internal fluid ports. This means Wilwood has eliminated the need for external fluid crossover tubes and a large center bridge assembly, resulting in a cleaner look and a more robust internal fluid path. The black anodized finish not only looks sharp but also adds a layer of durability.

This caliper is part of Wilwood's updated W4A / W6A series, representing the latest advancements in their caliper technology. When considering a brake upgrade of this caliber, it's important to ensure compatibility with your existing or planned rotor size and mounting setup. This caliper is sold individually, so you'll need to purchase the correct quantity for your vehicle's braking system.
