The DBA 4000 Series T3 T-Slotted Rear Brake Rotor is a high-performance replacement designed for Lexus IS F models from 2008 to 2012. Crafted from XG-150 high carbon alloyed iron, these rotors undergo Thermal Stability Profiling to withstand the intense heat and stress generated during aggressive braking. The use of advanced metallurgy ensures durability, consistent performance, and resistance to warping, making them ideal for street driving, track days, and demanding environments. Featuring DBA’s patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars, these rotors provide up to a 30% increase in surface area and 20% improved cooling efficiency over traditional straight vane designs. This innovative ventilation helps maintain optimal brake temperatures and enhances overall braking performance. The T3 bi-directional slot design, built upon the foundations of the T2 slot, includes CNC-machined tri-symmetrical slots that deliver a quieter, more responsive brake pedal feel while efficiently channeling brake pad friction gases and dust. The universal slot design eliminates the need for left or right-specific rotors, simplifying installation and ensuring uniform performance. These rotors come with thermo-graphic paint markings for easy heat monitoring and moisture-proof corrosion protection packaging for longevity. Suitable for various applications including street driving, SUVs, light utility vehicles, rally, and armored vehicles, the DBA 4000 Series T3 rotors combine innovative design with premium materials to deliver reliable and consistent braking power. Trust DBA’s engineering expertise for your Lexus IS F and experience superior stopping performance with a rotor built for high-stress conditions.
