Does this rotor come with hardware?

This product is for the brake rotor only. Installation hardware, such as lug nuts or brake pads, is typically sold separately and should be checked for compatibility.

What is Thermal Stability Profiling?

Thermal Stability Profiling is a heat treatment process applied by DBA to the rotor casting. It helps the iron handle the increased stress and heat generated during braking, contributing to the rotor's long-term durability and performance.

Product Details

If you're looking to replace the front brake rotors on your 2017-2023 Mazda MX-5 Miata, this 4000 Series HD rotor from DBA is a solid option. It's built with a high-carbon alloyed iron, specifically XG-150, which helps it handle the extra heat and stress that comes with harder braking. DBA also puts these rotors through a process called Thermal Stability Profiling to make sure they hold up over time.

What really sets these rotors apart is DBA's Kangaroo Paw ventilation system. Instead of standard straight vanes, it uses 144 diamond and teardrop-shaped pillars. This design increases the surface area by up to 30% and improves cooling efficiency by 20% compared to traditional rotors, which means more consistent braking performance, especially when you're pushing the car a bit.

This particular rotor has a smooth, OE-style finish, making it a popular choice for drivers who want the performance benefits of the 4000 Series but prefer a look that's closer to the original equipment. It's designed to fit right on your Miata without any modifications.
