4000 Series T3 Rotor

The DBA DBA4749S is a high-performance brake rotor from DBA's 4000 Series T3 line, engineered to be a direct replacement for specific Lexus models. This rotor is constructed from XG150 High Carbon Alloy Iron, which has been heat-treated to resist warping and cracking, thereby prolonging its lifespan. Key features of the DBA4749S include its Tri-symmetrical curve slots, which are designed to decrease vibration and noise, contributing to a quieter and smoother brake pedal feel. The rotor also benefits from the patented Kangaroo Paw ventilation system, featuring 144 diamond and tear-drop pillars that reduce brake fade and improve overall braking efficacy. Additionally, it incorporates an increased number of out-gassing exit locations to enhance brake stop uniformity and performance. This rotor is intended for demanding applications, with driving qualifiers listed as Extreme & Fleet Duty, Towing-Oversized Tires, Performance Street, and Street & Track Events. It boasts a top-tier stopping power rating of 5 out of 5, a low noise level rating of 1 out of 5, and is rated 4 out of 5 for performance over stock for track day and towing scenarios. The DBA DBA4749S is sold individually and features a coated finish for rust protection on non-friction surfaces. It is designed for use on the rear of various Lexus models, including the GS300, GS400, GS430, IS300, IS300 Sportcross, and SC430, spanning model years from 1998 to 2010.
