DBA Cross-Drilled Slotted Disc Brake Rotor (Single) Gold 303mm DBA2549X

DBA Cross-Drilled Slotted Disc Brake Rotor (Single) Gold 303mm Fits Mazda CX-5, CX-30

Sharing all the benefits of the 4000 Series, DBAs 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 aluminium hats (T6061-T6), held together with National Aerospace Standards (NAS) bolts and crimp nuts.

The 5000 Series share all of the performance technology featured in the 4000 Series, with the added benefits of further weight reduction and improved heat management via aluminium hats.

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

DBA offers both complete assemblies for first time replacement (hats and flat discs bolted together) along with replacement hats and flat disc rotors (rings).

This allows drivers to re-use their DBA 5000 Series hats with DBA replacement flat discs (rings).

DBA recommends the 5000 Series for high performance street vehicles, track day and club racing and rally applications.

DBAs 5000 Series rotors feature:

• Aluminium hats (T6061-T6)
• National Aerospace Standard (NAS) bolts and crimp nuts
• Replacement disc rotors available
• XG-150 High Carbon Alloyed Iron
• TSP (Thermal Stability Profiling)
• Thermo-graphic Paint markings (THGP)
• Direct replacement suitability
• Moisture proof corrosion protection packaging

• T3 Slot 48 precision CNC machined slots
• Kangaroo Paw 144 diamond and tear drop pillar ventilation system*
• XG150 High Carbon Alloyed Iron
• Thermographic Temperature Monitoring
• Paint protection on non-friction areas

Advantage

• Tri-Symmetrical curve slots dampens the vibration harmonics or noise
• Increased number of out-gassing exit points for brake pad friction gasses to escape through
• Universal slot design
• Increased surface area resulting in greater heat dissipation
• An increase in thermal capacity property allows the rotor to handle constant extremes of heat over extended periods of time
• Special formulation designed to respond to DBAs TSP process
• Heat paint markings change colour at specific temperature thresholds
• When temperature thresholds are exceeded paint markings will permanently change colours
• Reduces corrosion

Benefit

• A quieter, responsive and smoother brake pedal feel
• Increases the consistency and effectiveness of every brake stop
• Eliminates the need for left and right discs
• Minimises brake fade and increases braking effectiveness
• Prolongs service life for both pads and rotors. Reduces mechanical damage and associated costs
• Minimises warping and cracking and prolongs the service life of the rotor
• Offers the driver a clear indication of peak braking temperatures
• Allows the driver to monitor rotor fatigue and decide on rotor replacement and to assist resellers with warranty claims
• Stops any unsightly rust formation

*Kangaroo Paw is not available on all part numbers
