OVERVIEW

DBA's 5000 Series T3 Slotted rotor represents the ultimate in direct-replacement 2-piece performance brake rotors for the GR platform. Engineered for street performance, track days, and club racing, the T3 features DBA's patented bi-directional tri-symmetrical slot design combined with aerospace-grade aluminum hats and high-carbon cast-iron rings for reduced unsprung weight, superior heat management, and responsive braking power. The T3 slot design increases exit points for brake pad friction dust and gases, delivering a quieter, more responsive, and smoother braking experience than conventional slot patterns.

FEATURES

• T3 Tri-Symmetrical Slot Design: DBA's patented bi-directional slot pattern with increased exit points for brake pad friction dust and gases, resulting in quieter, more responsive stops and improved consistency.
• Lightweight 2-Piece Composite Construction: Aerospace-grade billet aluminum (T6061-T6) center hat bonded to high-carbon cast-iron rotor ring via NAS bolts and crimp nuts.
• Thermal Stability Profiling (TSP): Optimized heat management for sustained track temperatures and late-braking scenarios without fade or warping.
• Reduced Unsprung Weight: Aluminum hats minimize unsprung mass, improving suspension response and reducing heat transfer to chassis and suspension components.
• Heat Paint Markings: Temperature-sensitive paint changes color at specific thresholds to indicate peak braking temperatures and monitor rotor fatigue.
• Universal Slot Design: No separate left/right disc nomenclature; one design works in both positions for simplicity and inventory efficiency.
• Aerospace-Grade Fastening: NAS bolts and crimp nuts ensure durability and reliability under extreme thermal and mechanical cycling.
• Proven Track Heritage: DBA rotors are trusted by performance drivers, motorsport competitors, and enthusiasts worldwide for consistent stopping power and reliability.
