The T3 4000 Series rotor's key feature over the Street T2 series is the XG150 High Carbon Alloyed Iron which minimizes warping and cracking and prolongs the service life of the rotors. This makes them suitable for hard use both on the road and race track.
As with every DBA rotor, the 4000 Series rotor bolts right onto the vehicle with no mechanical changes needed.
Features Thermal Stability Profiling (TSP) for improved heat handling and Thermo-Graphic paint markings for heat monitoring. The 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.
DBA's unique 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.
* Unidirectional slotting increases pad bite, reduces fade and delivers exceptional braking performance.
* Slots continually de-glaze the brake pads improving efficiency and reducing rotor scoring.
* Slots even out wear across the brake pad faces, increasing the effective contact area and extending rotor life.
* DBA's patented Kangaroo Paw internal structure features diamond-shaped pillars that provide increased surface area and greater heat dissipation, minimizes brake fade and increases braking effectiveness.
Fits ALL 1994-2000 Miata front, and 2001-2002 NON-SPORT size front.
