Product Details

If you're looking to upgrade your braking system for more assertive stopping power, this Wilwood Aero4 caliper is a solid choice. It's designed for performance applications where improved thermal management and consistent braking are key. This caliper features a red finish, giving your wheel well a sharp look while providing the performance you need.

This Aero4 caliper is built with a two-piece forged aluminum body, which is both strong and lightweight, helping to reduce unsprung weight. Inside, you'll find a pair of 1.50-inch pistons, carefully sized to work with a variety of brake systems and provide balanced braking force.

This caliper is sold individually, so be sure to order the correct side (left-hand or right-hand) and quantity for your vehicle's brake setup. It's a component that pairs well with performance brake rotors and pads to create a complete, high-performance braking package. Always refer to the manufacturer's installation instructions for proper setup and bleeding procedures.
