DBA GR86 / BRZ 4000 Series T3 Slotted Rotors - Front (Brembo)

Overview

High-performance 4000 Series T3 slotted front brake rotors engineered by Disc Brakes Australia. Designed for compatibility with select 86/BRZ models (Performance Package), dual 5×100 mm / 5×114.3mm bolt pattern, these rotors offer enhanced braking capability for both spirited street driving and occasional track use. 

Key Features & Benefits

• Advanced Cooling & Heat Management:
  Cast from high-carbon XG-150 alloyed iron and treated with Thermal Stability Profiling (TSP), these rotors are built to withstand high temperatures without warping or cracking, delivering reliable performance even under repeated heavy braking.

• T3 Tri-Symmetrical Slot Design:
  Precision CNC-machined tri-symmetrical slots efficiently evacuate brake dust, gases, moisture, and debris, improving pad bite and reducing brake fade. These slots also contribute to a quieter, more responsive, and smoother brake feel compared to standard designs.

• Kangaroo Paw Ventilation:
  Featuring DBA’s signature Kangaroo Paw vane system — a series of 144 diamond and teardrop shaped vents — these rotors increase surface area and airflow for up to a 20% improvement in cooling efficiency over conventional vented rotors, helping combat heat buildup and brake fade.
