Product Description

The DBA DBA4746XS 4000 Series XS rear brake rotor is engineered for drivers seeking enhanced braking performance combined with aggressive styling. Featuring DBA's XS design, this rotor integrates both cross-drilled holes and directional slotting to improve initial bite, gas evacuation, and braking response.

Constructed from high-carbon alloy cast iron and enhanced with Thermal Stability Profiling (TSP), this rotor is designed to withstand repeated heat cycles while maintaining structural integrity and consistent braking performance. The Kangaroo Paw ventilation system further improves cooling efficiency, reducing brake fade during spirited street driving conditions.

Designed for late-1990s Lexus LS400, SC300, SC400, and Toyota Supra rear applications, this rotor serves as a direct OEM replacement upgrade. It is best suited for street performance use where aesthetics and moderate performance enhancement are desired over full track durability.
