What is a 2-piece rotor ring and why would I need one?

A 2-piece rotor system separates the rotor ring from the caliper hat. This design allows for better thermal management and can reduce unsprung weight. You would need a replacement ring if the original ring is worn or damaged, but the hat assembly is still in good condition.

What is the benefit of drilled rotors?

Drilled rotors have holes that help to vent hot gases and heat away from the braking surface. This can improve braking performance, especially during repeated hard stops, by reducing the risk of brake fade and keeping the pads and rotors cooler.

Does this rotor ring come with the caliper hat or mounting hardware?

No, this product is a replacement rotor ring only. It is designed to be used with the appropriate Brembo caliper hat assembly and mounting hardware, which are sold separately.

Product Details

This is the Brembo 412x38mm LH Drilled Replacement Rotor Ring, specifically designed to work with the Brembo 1Q1.9631A2 caliper system. If you're looking to maintain or restore the high-performance braking capabilities of a vehicle equipped with this advanced Brembo setup, this rotor ring is a critical component. It's engineered to provide the stopping power and heat dissipation necessary for demanding driving conditions.

Brembo is well-known for its commitment to braking technology, and this rotor ring is a testament to that. It features a drilled surface pattern, which helps to vent gases and heat away from the braking surface. This improved airflow is crucial for preventing brake fade during repeated hard stops, ensuring consistent performance when you need it most. The 412mm diameter and 38mm thickness are precisely matched to the 1Q1.9631A2 caliper to ensure optimal contact and braking force. This is a replacement ring only, intended to be used with the appropriate Brembo hat assembly.

When replacing rotor rings, it's important to ensure that the caliper mounting hardware and the rotor hat assembly are in good condition. Always refer to the manufacturer's installation instructions for the correct procedure and any specific torque specifications required for this high-performance braking component. Proper installation is key to achieving the full benefit of Brembo's braking technology.
