DBA's, Disc Brake Australia Mazda Miata rotor features Thermal Stability Profiling for improved heat handling and Thermo-Graphic paint markings for effective heat monitoring.
The XS premium cross-drilling and slotting design provides efficient braking performance on the street (for street use only).
Price is for one rotor, and the sport rotors fit the 2004-2005 Mazdaspeed Miata.
As with every DBA rotor, the 4000 Series rotor bolts right onto the vehicle with no mechanical changes needed. DBA's enhanced-performance, slotted rotor features Thermal Stability Profiling (TSP) for improved heat handling and Thermo-Graphic paint markings for effective heat monitoring.
Thermo-Graphic markings are placed on the outer edge of each DBA 4000 series disc rotors and are used to monitor the core temperatures achieved during braking application. The markings change color as the rotor heats up to alert the driver to rotor temperatures that exceed optimum levels.
The ''Kangaroo Paw'' design features a series of 144 diamond- and tear drop-shaped pillars and columns individually spaced between the rotor faces. This system provides two key advantages. First, is the ability to cool the rotor faster than ever before. As the disc rotor rotates, aerodynamic turbulence around the individual pillars and columns is generated, increasing the force of hot air out from within the internal areas of the rotor. Second is increased dimensional stability across the disc rotor directly achieved by the individually spaced pillars and columns.
These advantages increase the disc rotor's efficiency by as much as 20% when compared to conventional rotor designs. A 20% increase in disc rotor efficiency directly translates to reduced brake operating temperatures, brake fade, disc rotor stresses, disc thickness variation, run-out and shudder. All 4000 series rotors also benefit from DBA's "Longlife Slotted" design. The rotors are manufactured to QS-9000 quality standards using premium grade materials with a high iron content and dense metal matrix resulting in long wear and safe, consistent stopping power.
