DBA DBA43029S 4000 Series T3 Slotted Disc Brake Rotor

The DBA DBA43029S is a 4000 Series T3 slotted disc brake rotor from Disc Brakes Australia (DBA), engineered as a direct-replacement, single-piece performance upgrade over standard OE rotors. Featuring DBA's patented bi-directional T3 slot design, this rotor delivers improved braking consistency, responsiveness, and heat management for both street and performance driving.

T3 Slot Technology:

• Precision CNC-machined tri-symmetrical slots built on DBA's proven T2 slot foundation
• Bi-directional slot pattern allows universal left/right fitment
• Slots evacuate brake pad friction dust and gases, reducing pedal fade and improving bite consistency
• Quieter, smoother pedal feel compared to non-slotted rotors

4000 Series Construction & Features:

• Cast from XG-150 high carbon alloyed iron for superior strength and heat resistance
• Thermal Stability Profiling (TSP) — a proprietary DBA heat-cycling process that relieves internal casting stresses, improves microstructure stability, and reduces metal fatigue under intense braking
• Patented Kangaroo Paw vane ventilation with 144 diamond and teardrop-shaped pillars — delivers up to 30% more surface area and 20% better cooling efficiency versus traditional straight-vane designs
• Thermo-Graphic Heat Paint (TGHP) markings on the rotor edge change color at predetermined temperature thresholds, allowing drivers to monitor peak rotor temperatures and select appropriate brake pad compounds
• Painted non-friction surfaces resist corrosion and enhance appearance
• Centre split core castings for increased heat transfer and thermal efficiency

Direct Replacement Fitment:

• Bolt-on installation — no mechanical modifications required
• Sold individually

The DBA DBA43029S is an ideal upgrade for performance-minded drivers who demand reliable, fade-resistant braking on the road or occasional track use. Compatible with DBA's range of performance brake pads for a fully optimized braking system.
