Wilwood Caliper-Aero4-L/H - Black Anodize 1.88/1.62in Pistons 1.25in Disc

The internal fluid ports on this Wilwood Aero4 caliper are a notable design choice, eliminating the need for external crossover tubes and a large center bridge. This not only cleans up the look but also contributes to a more robust and integrated fluid path. This forged four-piston caliper is built to handle serious stopping demands, whether you're on the street or pushing your vehicle on the track. Its design draws directly from race technology, offering a significant upgrade over stock braking components.

Wilwood engineered this caliper for broad adaptability, making it a strong option for a variety of heavy-duty braking requirements. It's designed to work with rotor diameters ranging from 12.88 inches up to 15.00 inches, giving you flexibility when choosing your braking setup. The caliper features staggered piston sizes – 1.88 inches for the inner pistons and 1.62 inches for the outer – which helps to balance pressure distribution across the brake pad for more even wear and consistent stopping force. The black anodized finish isn't just for looks; it adds a layer of durability and corrosion resistance to the forged aluminum body.

This Aero4 caliper is the latest update to Wilwood's W4A and W6A series, incorporating their most recent advancements. When planning your brake system upgrade, consider that this caliper is designed for radial mounting and offers multiple options for piston volume to fine-tune your braking performance. It's a well-built component intended to provide reliable, heavy-duty stopping power for demanding applications.
