4000 Series XD
Description
The 4000 Series XD adds a non-directional cross-drilled and dimpled rotor design to the proven 4000 Series foundation, stepping up from the HD with additional cooling benefits and a more aggressive visual presence. Where traditional cross-drilled designs compromise structural integrity, DBA’s XD uses a combination of drilled holes and dimples to provide enhanced structural support above conventional cross-drill techniques, better aesthetics without the engineering compromise. Cooling benefits are improved above the HD specification, and the non-directional design maintains universal left/right fitment. Not recommended for heavy off-road or sustained track day use.
