What is the main purpose of a rotor hat?

A rotor hat serves as the central mounting point for your brake rotor. It connects the rotor securely to the vehicle's hub assembly, ensuring proper alignment and stability during braking.

What material is this rotor hat made from?

This Wilwood rotor hat is constructed from aluminum. Aluminum is chosen for its good strength-to-weight ratio, which can help reduce unsprung mass on your vehicle.

What does the '1.140 OffSet' specification mean?

The offset measurement indicates how far the rotor mounting surface is positioned relative to the hub mounting surface. This is critical for ensuring proper clearance between the rotor, caliper, and wheel.
