FRONT 5000 SERIES T3 BRAKE RING

• Diameter (mm): 326
• Axle: Front
• Per Car Qty Required: 2

5000 SERIES T3 is the ultimate in direct replacement 2 piece performance brake rotors Featuring all the benefits of the 5000 Series along with DBAs patented world renowned T3 bi directional slot design.

Built on the foundations of DBAs T2 slot, the T3 slot design features additional precise CNC machined tri symmetrical slots, resulting in an even quieter, more responsive and smoother braking experience. The T3 slot increases the number of exit points for brake pad friction dust and gases to escape through, further increasing the consistency and effectiveness of every brake stop.

PRODUCT INFO

Sharing all the benefits of the 4000 SERIES, 5000 SERIES rotors are a composite 2 piece direct replacement brake rotor. DBA uses only the highest quality materials to ensure optimal performance under the most strenuous circumstances, combining high carbon cast iron rings with aerospace grade aluminum hats (T6061-T6) held together with National Aerospace Standards (NAS) bolts and crimp nuts.

5000 SERIES shares all of the performance technology featured in the 4000 SERIES, with the added benefits of further weight reduction and improved heat management via the aluminum hats.

The use of aerospace grade aluminum hats reduces the unsprung weight of the brake rotors, whilst allowing for uniform radial disc expansion throughout the cast iron rings and reduced heat transfer from disc to hub via the aluminum hats.

The T3 slot design further increases the number of out-gassing exit points on the rotor surface, and assists in the removal of unwanted dust and debris between the rotor and brake pad, which otherwise could cause pad glazing and loss of brake performance.

The development of the revolutionary bi-directional slot design eliminates the concern of having opposing left and right designated brake rotors, with DBA T2 and T3 rotors able to be used on either side of your vehicle.

The bi-directional slot design also assists in dampening the vibration harmonics (noise), resulting in a quieter, more responsive and smoother brake pedal feel.

FEATURES:

1. Two Piece Design Hat and rings sold as complete assemblies and as individual components, for more economical replacement options.
2. Surface Design Symmetrical slots facilitate the exit of friction dust and gasses, for a quieter and more responsive pedal feel.
3. DBA Aluma-Lite Aluma-lite center hat / bell made from extra lightweight 6061 T6 aircraft aluminum, reducing the unsprung weight for better vehicle handling and minimizing heat transfer to the wheel hubs.
4. Anti Rust Painted non-friction areas to prevent rust and enhance appearance.
5. Bi-Directional Use Symmetrical slotting and/or drilling for universal left/right use.
6. Thermal Stability Profiling (TSP) Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability. Centre split core castings for increased heat transfer and thermal efficiency.
7. Thermal Efficiency Centre-split core castings for increased heat dissipation and thermal efficiency.
8. CBN Cubic Boron Nitride machine turned finish, minimizing disc thickness variation and the potential for pad “knock” and resulting premature wear.
9. Thermographic Heat Paint (TGHP) Paint markings change color at specific temperature thresholds to assist with the monitoring of braking temperatures and rotor fatigue.
10. High Carbon Alloyed Iron Formulation allows for optimal interaction with DBA’s thermal stability profiling. Increases the capacity of the rotor to handle constant and extreme heat over prolonged periods.
11. Kangaroo Paw Unique Kangaroo Paw vein design for up to 20% better heat dissipation, increasing braking effectiveness and prolonging brake life.
12. NAS Bolts & Nuts National Aerospace Standards (NAS) bolts and crimp nuts for maximum strength at minimal weight.
