Product Description

The DBA 4655S-10 is a 4000 Series T3 slotted rear brake rotor for the 2004-2007 Subaru Impreza WRX STI. Its dual-drilled 10-stud hole design accommodates both the 5x100 bolt pattern used on the 2004 STI and the 5x114.3 pattern used on the 2005-2007 STI in a single rotor. At 316mm in diameter, it is a direct bolt-on replacement for the OEM rear rotor with no modifications required.

DBA's T3 tri-symmetrical curved slot design features 48 precision CNC machined slots that continually de-glaze brake pads for consistent bite, improved water and gas evacuation, and a quieter, smoother pedal feel compared to straight-cut slots. Kangaroo Paw ventilation uses 144 diamond and teardrop-shaped pillars to increase the rotor's internal surface area by up to 30% and improve cooling efficiency by up to 20% over a traditional straight vane design. XG-150 high carbon alloyed iron combined with DBA's proprietary Thermal Stability Profiling (TSP) process relieves manufacturing stresses through controlled heat cycling, delivering superior fatigue resistance under extreme and repeated braking loads. Heat-sensitive Thermo-Graphic Heat Paint markings on the rotor hat allow monitoring of peak braking temperatures during track use. Sold individually -- order 2 for a complete rear axle set. Backed by DBA's 12-month / 12,000-mile warranty.
