DBA Rear T-Slotted T3 4000 Series Rotor 07-09 Lexus IS F

DBA Rear T-Slotted T3 4000 Series Rotor improves braking control and delivers a quieter, more responsive and smoother brake pedal feel for the 07-09 Lexus IS F.

Built on the foundations of DBA's T2 slot, the T3 slot design introduces additional, precise CNC-machined tri-symmetrical slots that refine pad contact and gas evacuation. These engineered slots increase the number of exit points for brake pad friction dust and gases to escape, helping maintain consistent friction at the pad-rotor interface.

• Tri-symmetrical T3 slots: Precisely routed to provide multiple exit paths for dust and gases, which reduces pad glazing and supports repeatable braking performance under varied conditions.
• CNC-machined slot geometry: Ensures consistent slot profile and placement across the rotor surface, contributing to uniform pad wear and a stable pedal feel.
• Design derived from T2 platform: Retains the proven qualities of the original T2 slot while adding targeted improvements for quieter operation and enhanced pedal response.
• Improved dust and gas evacuation: More exit points reduce the buildup of friction by-products, which helps preserve predictable brake modulation and reduces noise during engagement.

DBA engineering focuses on functional improvements that matter to performance and reliability—slot geometry and manufacturing precision that directly affect pad interaction, brake response, and operational noise.
