DBA 5000 series Slotted L/R Rotor Only DBA5048.1RS (2 pcs)

DBA 5000 Series 2-Piece Performance Brake Rotors

Sharing all the benefits of the 4000 Series, DBA’s 5000 Series rotors are high-performance, 2-piece direct replacement brake rotors. Manufactured using the highest quality materials, the 5000 Series combines XG-150 high carbon cast iron rings with aerospace-grade T6061-T6 aluminium hats for unmatched thermal performance and reduced weight.

The use of aluminium hats not only reduces unsprung weight but also enhances heat management by limiting heat transfer to the hub and allowing uniform radial expansion through the disc ring. The modular design allows the reuse of aluminium hats with DBA replacement rotor rings.

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

Technology Benefits

T3 Slot Design

Advantage: Tri-symmetrical curved slots reduce vibration harmonics and noise

Benefit: Quieter, smoother, and more responsive brake pedal feel

Advantage: Increased number of out-gassing exit points for pad friction gases

Benefit: Improved consistency and effectiveness of each brake stop

Advantage: Universal slot pattern

Benefit: No need for separate left/right rotors

Kangaroo Paw Ventilation

Advantage: Increased internal surface area for cooling

Benefit: Minimised brake fade, better heat dissipation, and enhanced performance

Benefit: Extended pad and rotor life; reduced mechanical wear

XG150 High Carbon Iron

Advantage: Higher thermal capacity for extreme heat cycles

Benefit: Minimises warping and cracking; long rotor lifespan

Thermal Stability Profiling (TSP)

Advantage: Enhanced structural resistance under thermal stress

Benefit: Reduces rotor deformation and increases durability

Thermographic Temperature Monitoring

Advantage: Heat-sensitive paint indicators show peak brake temps

Benefit: Enables rotor fatigue tracking and assists with replacement or warranty decisions

Paint Protection on Non-Friction Areas

Advantage: Anti-corrosion coating

Benefit: Prevents rust and maintains product appearance
