DBA DBA43467S 4000 Series T3 Slotted Rear Rotor for Toyota GR Yaris GR Corolla

Vehicle Fitment

• 2020-present Toyota GR Yaris (GXPA16, Gen 1 & Gen 2, Rear, 1.6L G16E-GTS Turbo I3, AWD)
• 2022-present Toyota GR Corolla (GZEA14, Rear, 1.6L G16E-GTS Turbo I3, AWD) - All Trims: Core, Premium, Circuit Edition, Morizo Edition

Fitment Notes

• Rear axle position only - a separate DBA part number is required for the front rotors on the GR Yaris and GR Corolla
• Solid rear rotor design - direct replacement for the OEM solid rear disc on both the GR Yaris and GR Corolla platforms
• Sold individually - order quantity 2 for a complete rear axle replacement
• Recommended for use with DBA Xtreme Performance (XP) or Street Performance (SP) brake pads for best results

Features

• T3 Tri-Symmetrical Slot design features 48 CNC-machined curved slots arranged in three directions, evacuating brake dust and gases efficiently for a quieter, more responsive pedal feel versus non-slotted and T2 designs
• XG-150 High Carbon Alloyed Iron construction resists warping and thermal fatigue under the repeated hard braking that the GR Yaris and GR Corolla's power output and AWD system invite on track and mountain roads
• Thermal Stability Profiling (TSP) heat-treats the iron microstructure to improve fatigue resistance and maintain dimensional stability through repeated heat cycling
• Kangaroo Paw® pillar vane ventilation - 144 diamond and teardrop-shaped pillars increase cooling surface area by up to 30% and improve heat dissipation by up to 20% versus conventional straight-vane rotors
• Thermo-Graphic Heat Paint (THGP) markings on the rotor edge change colour at specific temperature thresholds, allowing drivers to monitor brake heat and optimise pad compound selection
• Anti-rust paint on all non-friction areas protects the hat and vanes from corrosion without affecting braking performance

Product Description

The DBA DBA43467S is a 4000 Series T3 slotted solid rear brake rotor engineered for the Toyota GR Yaris (GXPA16, all generations) and Toyota GR Corolla (GZEA14), two of the most driver-focused AWD hot hatches available. At 297mm, this is a direct OEM-diameter replacement for the rear solid disc on both platforms, delivering a meaningful step up over the factory rotor through DBA's XG-150 high-carbon iron, Kangaroo Paw vane cooling, and T3 tri-symmetrical slot pattern.

The T3 slots clear friction gases and pad debris consistently with each stop, keeping the pad-to-rotor contact surface clean for predictable, consistent rear brake response - especially important on AWD rally-inspired cars where brake balance and rear stability matter. Thermal Stability Profiling ensures the rotor maintains its shape under repeated heat cycles, while Thermo-Graphic Heat Paint markings give track and circuit drivers a quick visual read of peak temperatures reached. A direct bolt-on replacement requiring no modifications.
