Product Description

The DBA 4655XS-10 4000 Series XS Gold Drilled/Slotted Rear Brake Rotor is engineered for Subaru WRX STI owners seeking a performance upgrade over standard OEM rear rotors. Featuring a premium drilled and slotted surface design, this rotor increases exit points for brake pad friction dust and gases, improving brake bite and responsiveness while maintaining smooth pedal feel. The attractive gold-finished hub also adds a visual upgrade.

Constructed from high carbon alloyed iron and treated with Thermal Stability Profiling (TSP), the DBA4655XS-10 delivers improved heat resistance and reduced warping under repeated hard braking. The Kangaroo Paw ventilation system with 144 pillars enhances cooling efficiency, making this rotor ideal for spirited street driving and occasional performance duty. Designed as a direct bolt-on rear replacement, it fits 2004-2007 Subaru Impreza WRX STI models including the 2007 WRX STI Limited with AWD and 2.5L H4 engines.
