Description

The DBA 4000 Series T3 brake rotor offers a significant upgrade over standard OE brake components, designed for those who demand enhanced performance and reliability. This single-piece rotor features DBA's proprietary T3 bi-directional slot design, which is an evolution of their T2 slot. The T3 design incorporates additional, precisely machined tri-symmetrical slots that improve the quietness, responsiveness, and smoothness of the brake pedal feel. These slots effectively increase the exit points for brake pad friction dust and gases, ensuring more consistent and effective braking performance with every application. Constructed from XG-150 high-carbon alloyed iron, the DBA 4000 Series T3 rotor is built for superior quality and durability. This material composition allows the rotor to withstand greater stress and heat compared to standard OE rotors, making it suitable for a wide range of demanding driving conditions. The rotor also features TSP thermal stability profiling for optimal cooling and performance, and thermo-graphic paint markings that allow for quick identification of temperature levels. Its direct replacement design ensures easy installation. DBA's commitment to quality extends to its packaging, which is moisture-proof and corrosion-protected to maintain the rotors in top condition upon arrival. The 4000 Series HD variant offers a smooth OE-style finish, appealing to drivers who require the performance benefits of the 4000 Series but prefer a more conventional aesthetic, such as those in controlled race divisions. The rotor's stopping power is rated at 3/5, with a noise level of 2/5, and a performance-over-stock rating of 2 (Performance/Commuter). This brake rotor is specifically designed for the front axle and has an outside diameter of 280mm, a height of 54mm, and a thickness of 30mm. It is compatible with various Nissan 300ZX models from 1990 to 1996, including 2+2, Base, Turbo, and Naturally Aspirated variants. The product is sold individually.
