4000 Series HD Brake Rotor

The DBA DBA42951 4000 Series HD brake rotor offers an upgraded braking solution with an OE-style smooth finish, appealing to those who desire improved performance while maintaining a factory aesthetic. Constructed from high-carbon alloyed iron (XG-150) and featuring Thermal Stability Profiling (TSP), the DBA42951 is built to withstand the increased stress and heat generated during intense braking. Its unique design incorporates DBA's patented Kangaroo Paw ventilation, utilizing 144 diamond and teardrop-shaped pillars. This advanced ventilation system significantly enhances surface area, leading to up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs. Installation is straightforward due to its direct replacement suitability. The rotor also comes with moisture-proof, corrosion-protection packaging to ensure it arrives in optimal condition. Thermo-graphic paint markings are included to aid in quick identification of temperature levels during use. This rotor is specifically designed for the rear of 2006-2015 Mazda MX-5 Miata models, including various trims like the 25th Anniversary Edition, Club, Grand Touring, GS, GT, GX, and Sport. It is also compatible with certain Mazda 6 and Lincoln MKZ models, as detailed in the fitment table.
