What size brake rotors can I use with this Wilwood Aero4 caliper?

This Aero4 caliper is designed to accommodate a wide range of rotor diameters, specifically from 12.88 inches up to 15.00 inches. You'll need to ensure your rotor size falls within this range for proper fitment.

Does this caliper come with mounting brackets or brake pads?

This product listing is for the Wilwood Aero4 caliper itself, which includes the caliper body and internal components. Mounting brackets, brake pads, rotors, and brake fluid are typically sold separately and must be chosen based on your specific vehicle application.

If you're looking to significantly upgrade your vehicle's braking performance for demanding street use or track days, the Wilwood Aero4 forged caliper is a solid choice. This caliper is built around a robust forged aluminum body, which is both strong and lightweight, helping to reduce unsprung weight. It features four pistons – a larger 1.88-inch piston and a smaller 1.62-inch piston on each side – designed to work together for balanced and powerful braking force. The internal fluid ports are an updated design that eliminate external crossover tubes, leading to a cleaner look and potentially improved fluid dynamics.

This Aero4 caliper is engineered for versatility, capable of working with rotor diameters from 12.88 inches up to 15.00 inches, making it adaptable to a wide range of vehicle applications. The radial mounting design simplifies installation on many setups. Wilwood has incorporated race-proven technology into this caliper, aiming to provide consistent and reliable stopping power even under heavy use. The red finish adds a noticeable visual upgrade to your wheel well.

When installing these calipers, it's important to ensure you have compatible brake rotors and the correct mounting brackets for your specific vehicle application, as these are sold separately. Proper brake fluid and bleeding procedures are also crucial for optimal performance. This caliper is a significant step up from most factory braking systems, offering improved feel and fade resistance.
