What is included in this Wilwood caliper kit?

This kit includes one left-hand AERO4 brake caliper. It is designed with staggered pistons (1.88-inch and 1.62-inch) and is intended for use with 1.25-inch thick rotors.

What type of rotor thickness does this caliper require?

This Wilwood ST AERO4 caliper is specifically designed to work with rotors that are 1.25 inches thick. Using the correct rotor thickness is important for proper caliper function and braking performance.

What is the benefit of the staggered piston design?

The staggered piston arrangement helps to distribute braking force more evenly across the brake pad surface. This leads to improved pad wear and more consistent, effective stopping power.
