Product Description

The DBA 4000 Series T3 Slotted Front Brake Rotor (DBA4654S-10) is a high-performance brake rotor engineered as a direct replacement for select Subaru and Toyota/Scion performance vehicles with dual bolt pattern front brakes. The unique 10-lug design incorporates both 5x100 mm and 5x114.3 mm patterns on a single rotor, allowing this part to fit a broader range of compatible vehicles without changing wheel hubs or mounting hardware. The tri-symmetrical T3 slot pattern and Kangaroo Paw ventilation enhance cooling and brake pad bite for consistent stopping power in spirited driving conditions.

Constructed from premium high carbon alloyed iron and treated with Thermal Stability Profiling (TSP), the DBA4654S-10 rotor delivers improved resistance to heat-related warping and cracking compared to many standard OE rotors. The slotted design helps expel brake dust and gases while promoting smoother pedal feel. Sold individually, you can replace one side at a time or order two rotors for a complete front axle upgrade to boost braking performance and confidence on compatible Subaru WRX STI, BRZ, and Toyota 86 front brake systems.
