Wilwood Adapter Rotor/Hat Register Ring 2.33in Dia. - 2 Pack

When you're upgrading your braking system, especially with aftermarket components like Wilwood calipers and rotors, ensuring everything centers up correctly is key. These adapter rotor/hat register rings are designed to help you achieve that precise alignment. They fit between your brake rotor and the wheel hub, acting as a guide to keep the rotor perfectly centered. This is important because an off-center rotor can lead to uneven pad wear, vibration, and reduced braking performance over time.

This particular set from Wilwood gives you two of these register rings, each with a 2.33-inch diameter. They're made to work with specific Wilwood rotor and hat combinations, helping to bridge the gap and ensure a snug, accurate fit. While they might seem like a small piece of the puzzle, getting these details right makes a big difference in how your entire brake setup performs and lasts.
