2x DBA Front 5000 Disc Brake Rotors for Mini Cooper R56 Clubman F54 Countryman

Sharing all the benefits of the 4000 Series, 5000 Series rotors are a composite 2 piece direct replacement brake rotor. DBA use 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.

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 aluminium hats.

The use of aerospace grade aluminium 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 aluminium hats.

DBA offer both complete assemblies for first-time replacement (i.e. hats and rotor rings bolted together) along with replacement hats and rings. This allows drivers to re-use either component as required.

TWO-PIECE DESIGN - 1
Hat and rings sold as complete assemblies and as individual components, for more economical replacement options.

SURFACE DESIGN - 2
Symmetrical slots and/or chamfered drill holes facilitate the exit of friction dust and gasses, for a quieter and more responsive pedal feel.

DBA ALUMA-LITE - 3
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.

HIGH CARBON ALLOYED IRON - 10
Formulation allows for optimal interaction with DBA's thermal stability profiling (TSP). Increases the capacity of the rotor to handle constant and extreme heat over prolonged periods.

KANGAROO PAW - 11
Unique Kangaroo Paw vane design for up to 20% better heat dissipation, increasing braking effectiveness and prolonging brake life.

NAS BOLTS & NUTS - 12
National Aerospace Standards (NAS) bolts and crimp nuts for maximum strength at minimal weight.

ANTI RUST - 4
Anodised aluminium hat to prevent rust and enhance appearance.

BI-DIRECTIONAL USE - 5
Symmetrical slotting and/or drilling for universal left/right use.

THERMAL STABILITY PROFILING - 6
Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability.

THERMAL EFFICIENCY - 7
Centre split core castings for increased heat transfer and thermal efficiency.

CBN - 8
CBN (Cubic Boron Nitride) machine turned finish, minimising disc thickness variation and the potential for pad "knock" and resulting premature wear.

THERMOGRAPHIC HEAT PAINT - 9
Paint markings change colour at specific temperature thresholds to assist with the monitoring of braking temperatures and rotor fatigue.

*Some variants may not contain all features.

5000 Series HD features a smooth OE style rotor finish, popular for drivers looking for the benefits of a 5000 Series rotor but requiring no slot, cross-drilled or dimpled designs.

5000 Series direct replacement rotors are available as complete assemblies (hat and rings bolted together for direct replacement), or as replacement parts (hats or rings).

This allows drivers that own DBA 5000 Series rotors the option to replace only the cast iron rotor rings, while keeping their previously used aluminium hats. This is not only cost effective for those that are hard on brakes, but it allows for easy replacement of DBA hats or rings.

DBA recommend that aluminium hats should always be thoroughly inspected for damage and wear when only replacing the 5000 Series rings, along with the use of DBA spec bolts and nuts.

DBA recommend 13 Nm or 9.6 ft lb of torque when tightening the NAS nut and bolt assembly.
