DBA 43051S-10 4000 Series T3 Slotted Rear Brake Rotor

The DBA 4000 Series T3 Slotted Brake Rotor is a direct replacement single-piece performance brake rotor designed for drivers seeking upgraded braking performance above and beyond standard OE levels. This rear rotor is specifically engineered for Subaru WRX STI models equipped with Brembo Yellow Spec R 6-pot calipers and 19-inch wheels.

Advanced T3 Slot Technology:

Built on the foundations of DBA's T2 slot, the T3 slot design features additional, precise, CNC machined tri-symmetrical slots, resulting in an even quieter, more responsive and smoother brake pedal feel. The T3 Slot features 48 precision CNC machined tri-symmetrical curve slots that help reduce vibration and improve braking performance for the street or the track. The T3 adds several more gas scavenging slots to the rotor face, going from 32 slots in the T2 to 48 slots in the T3.

Premium Materials and Construction:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy is able to handle the increased stress and heat generated under intense braking applications, time and time again.
• Patented Kangaroo Paw ventilation implements a series of 144 diamond and teardrop patterned pillars, achieving up to a 30% increase in surface area and 20% improvement in cooling efficiency compared to a traditional straight vane design.
• 5x114.3 bolt pattern with unidirectional design
• One-piece construction with XG150 High Carbon Alloyed Iron material
• XG150 High Carbon Alloyed Iron minimizes warping/cracking and prolongs the service life of the rotor.

Thermal Stability Profiling (TSP):

TSP is a DBA proprietary process where XG-150 grey iron is subjected to prolonged heat cycles under strictly controlled conditions to relieve any internal stresses, ensuring maximum thermal stability and reduced metal fatigue in extremely high demanding applications.

Thermo-Graphic Heat Paint Monitoring:

DBA's patented Thermo-Graphic Heat Paint (TGHP) markings feature paint stripes of Green, Orange and Red that change color once your rotor reaches predetermined critical temperature thresholds. Green changes to white at 856°F, orange changes to yellow at 1022°F and red changes to white after 1166°F, with ideal braking temperatures between 850°F and 1000°F.

Key Benefits:

• Tri-symmetrical curve slots create a quieter, responsive and smoother brake feel while increasing exit points for brake pad friction gases to escape.
• Increased surface area resulting in greater heat dissipation
• Rated for severe motorsports use
• On average, these rotors last 3x longer than most other rotors on the market
• Unidirectional slotting increases pad bite, reduces fade and continually de-glazes brake pads improving efficiency
• Black high temperature coating on non-friction areas for corrosion protection

Applications:

These features combined make this a great rotor for your street car, and for the weekend warrior who demands the most out of their car, on and off the track. Suitable for daily driving, spirited street use, track days, and motorsport applications.
