DBA 5000 Series 2-Piece Drilled & Slotted Front Rotor | Nissan 370Z Sport / Infiniti G37 Sport / Q60 Sport | Black Hat | DBA52314BLKXS
DBA 5000 Series 2-Piece Drilled & Slotted Front Rotor – Nissan 370Z Sport | Infiniti G37 Sport | Q60 Sport | Black Hat | DBA52314BLKXS
⚠️ PRICE IS PER SINGLE ROTOR — One rotor per order. Two are required for a complete front axle replacement. Add 2 to cart.
⚠️ AKEBONO SPORT CALIPERS ONLY — Fits vehicles equipped with Akebono Sport front calipers. Confirm your trim level before ordering. Does not fit base models with the standard (non-Sport) brake package.
DBA’s 5000 Series XS 2-piece drilled & slotted front rotor for the Nissan 370Z Sport, Infiniti G37 Sport (Coupe and Sedan), and Infiniti Q60 Sport — all fitted with Akebono Sport front calipers. High carbon alloyed iron ring with combined drill and slot surface treatment, paired with a T6061-T6 Aluma-lite aluminium hat in black anodised finish. 355mm outer diameter, 32mm thickness. Sold individually — one rotor per order.
XS — Drilled & Slotted Surface
The 52314BLKXS is the drilled & slotted variant of the 5000 Series rotor for this application — combining both surface treatments on the same rotor face. The slots channel friction dust and gases away from the pad face for consistent pad-to-rotor contact and improved pedal feel. The drill holes provide additional gas venting and contribute to the aggressive visual appearance common to track-day and performance builds. Note: drilled rotors are not recommended for sustained hard track use where repeated high-heat cycles may stress the drill hole perimeter over time — for pure track applications the slotted-only 52314BLKS is the more durable choice. For high-performance street and occasional track/track day use, the XS drilled & slotted is well suited.
5000 Series — 2-Piece Construction
- High Carbon Alloyed Iron Ring: DBA’s high carbon alloyed iron formulation increases thermal capacity and resistance to heat fade and cracking. Optimised for DBA’s Thermal Stability Profiling process
- Aluma-lite T6061-T6 Aluminium Hat: Extra lightweight 6061-T6 aircraft aluminium hat in black anodised finish. Reduces unsprung weight and minimises heat transfer from rotor to wheel hub. Hat is reusable — replacement rings sold separately
- Kangaroo Paw Vane Design: DBA’s patented Kangaroo Paw internal vane design provides up to 20% better heat dissipation for increased braking effectiveness and prolonged rotor life
- Radial Expansion: 2-piece design allows the iron ring to expand radially under heat without constraint, reducing warping risk
- NAS Hardware: National Aerospace Standards (NAS) bolts and crimp nuts — maximum strength at minimal weight
- Thermal Stability Profiling (TSP): Heat treatment cycles realign the microstructure of the iron for increased rotor stability and durability
- CBN Machine Finish: Cubic Boron Nitride machine-turned finish minimises disc thickness variation and reduces pad knock risk
- Thermographic Heat Paint (TGHP): Paint markings change colour at specific temperature thresholds — assists monitoring of braking temperatures and rotor fatigue
- Anti-Rust Paint: Non-friction areas painted to prevent rust
- Bi-Directional: Symmetrical drilling and slotting for universal left/right use
- Replaceable Ring: DBA replacement flat disc rings sold separately for hat reuse
Fitment — Akebono Sport Caliper Vehicles
- Nissan 370Z Z34 Sport (2009–2021) — front
- Infiniti G37 Coupe Sport (2008–2013) — front
- Infiniti G37 Sedan Sport (2009+) — front
- Infiniti Q60 Coupe Sport (2014+) — front
- All require Akebono Sport front calipers — confirm before ordering
Price is per single rotor — two required for a complete front axle set. Akebono Sport calipers required — does not fit base trim. For sustained track use, consider the slotted-only 52314BLKS — drilled rotors are better suited to street/occasional track use. Bed-in procedure required after installation. Do not use aggressive braking until bed-in is complete. Inspect rotor hardware torque after first heat cycle. Warranty: 12 months / 20,000 km / 12,000 miles. Made in Australia by DBA.
