DBA is a popular Australian brand producing quality brake components for the 86 BRZ FRS.

Sharing all the benefits of the 4000 SERIES, 5000 SERIES rotors are a composite 2 piece direct replacement brake rotor. We use 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. With the added benefits of further weight reduction and improved heat management via the aluminum hats, you have less rotating mass with better cooling. 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.

Built on the foundations of DBAs T 2 slot, the T 3 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.

DBA offers both complete assemblies for first time replacement (hats and flat discs bolted together) along with replacement hats and flat disc rotors. This allows drivers to re-use their DBA 5000 SERIES hats with DBA replacement flat discs (rings).

We recommend 5000 SERIES for high performance street vehicles, track day and club racing, rally applications and show vehicles.

DBA recommends a T3 slot for high performance applications.

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 centre hat / bell made from extra lightweight 6061 T6 aircraft aluminium, reducing the unsprung weight for better vehicle handling and minimising 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, minimising disc thickness variation and the potential for pad “knock” and resulting premature wear.
9. Thermographic Heat Paint (TGHP) Paint markings change colour 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.
