What is the benefit of a two-piece rotor design?

A two-piece rotor design, like the one in this Wilwood kit, separates the rotor ring from the hub assembly. This allows for independent thermal expansion, reducing stress on the rotor and hat. It also helps to lower unsprung weight, which can positively impact handling and suspension response.

Why are the rotors drilled?

The drilled holes in the rotor faces serve a couple of important functions. They help to vent hot gases and brake dust away from the pad surface, which can prevent brake fade and maintain consistent stopping power. They also contribute to cooling by allowing more airflow over the rotor.

What else might I need to complete this brake upgrade?

To get the most out of this rear brake kit, it's recommended to also perform a brake fluid flush with a high-temperature fluid. Ensure you have the necessary tools for brake caliper and rotor replacement, and always refer to the manufacturer's installation instructions for proper torque specifications.

Product Details

The two-piece rotor design in this Wilwood Pro-Matrix rear kit features a forged aluminum hat that connects to the iron rotor ring. This setup is specifically for the 2001-2005 Mazda Miata Sport, offering an improved braking solution over stock components. The drilled rotor faces help dissipate heat and gas, which is crucial for maintaining consistent stopping power, especially during spirited driving or track use.

Wilwood is known for its performance braking systems, and this kit is built with that reputation in mind. The forged aluminum hat not only reduces unsprung weight, which can improve handling, but also allows for thermal expansion of the rotor ring without inducing stress. The iron rotor itself is drilled to help vent gases and moisture away from the braking surface, preventing fade and ensuring a more reliable grip. This combination of materials and design choices results in a well-built rear brake upgrade that complements the Miata's sporty nature.

This kit includes everything you need to upgrade the rear brakes on your Miata. When installing, ensure you follow Wilwood's specific instructions for proper assembly and torque specifications to get the most out of this performance braking system. A proper brake fluid flush with a high-temperature fluid is also recommended to complete the upgrade.
