Product Description

The DBA DBA42759S 4000 Series T3 rear brake rotor is engineered specifically for high-performance braking applications, offering enhanced heat management, durability, and consistent stopping power. Designed with DBA's patented T3 tri-symmetrical slot technology, it improves pad bite while efficiently clearing dust, gases, and debris from the braking surface.

Constructed from high-carbon alloy cast iron and treated with Thermal Stability Profiling, this rotor is engineered to withstand repeated high-temperature braking events without warping or performance fade. The integrated Kangaroo Paw ventilation system further improves cooling efficiency, helping maintain stable braking performance during aggressive driving or track use.

This rotor is a direct rear replacement for the 2008-2012 Lexus IS F platform, making it ideal for performance street driving, spirited use, and OEM upgrade applications where braking consistency and heat resistance are critical.
