DBA 4000 Drilled & Dimpled Rotor - Front (2022+ WRX)

4000 Series disc brake rotors are a direct replacement single piece brake rotor, designed for drivers seeking upgraded performance braking above and beyond standard OE levels.

Cast from high carbon alloyed iron and undergoing Thermal Stability Profiling, DBA’s metallurgy can handle the increased stress and heat generated under intense braking applications, time and time again.

Featuring DBA’s Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars, DBA achieves up to a 30% increase in surface area and 20% improvement in cooling efficiency (as compared to a traditional straight vane design).

• 4000 Series XD variant features DBA’s non directional cross drilled and dimpled rotor design.
• The XD finish provides additional cooling benefits above the HD spec, along with enhanced sports aesthetics.
• The DBA mix of dimples and drilled holes provides enhanced rotor structural support above transitional cross drilled techniques.
• Drilled rotor configurations are not recommended for heavy off-road or track day usage.
• XD rotors are denoted by the suffix (XD) in 4000 Series part numbers.
