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

A two-piece rotor design separates the rotor ring from the hub or hat. This allows for better thermal expansion and contraction, which helps to reduce stress on the rotor and prevent warping, especially under heavy braking conditions.

What material is the rotor ring made from?

The rotor rings in the Wilwood Pro-Matrix kit are made from a specially formulated iron alloy. This material is chosen for its durability and its ability to resist brake fade when subjected to high temperatures.

Does this kit include everything needed for installation?

This kit includes the two-piece rear brake rotors. It is recommended to consult the manufacturer's installation guide for a complete list of required components and any additional hardware or brake pads you may need.

Product Details

This is the Wilwood Pro-Matrix 2-piece rear brake rotor kit for your 2001-2005 Mazda Miata Sport. If you're looking to upgrade your braking performance, especially for track days or spirited driving, this kit is a solid option. It replaces your stock rear rotors with a more robust setup designed for better heat management and consistent stopping power.

The Pro-Matrix kit features a two-piece rotor design. This means the rotor ring is separate from the hat, which helps to reduce thermal stress and prevent warping under heavy use. The rotor rings themselves are made from a specially formulated iron alloy that's known for its durability and resistance to fade. The hats are typically made from aluminum, which helps to keep the overall weight down while providing a strong mounting point for the rotor ring. This combination is built to handle the demands of performance driving.

When installing this kit, you'll find that the two-piece design can make rotor replacement simpler down the line, as you only need to replace the rotor ring itself. This kit is a significant step up from stock and is a popular choice for Miata owners looking to improve their car's stopping capability.
