• High carbon, heat-treated iron
• Patented Kangaroo Paw ventilation
• Unique drill and slot pattern for a proper direct-fit replacement

Best Technology and Materials in the Lineup

DBA's 4000 Series XS rotors combine the brand's best available technology and materials for maximum performance, starting with high carbon, heat-treated iron for genuine durability under hard use. That's paired with the same patented Kangaroo Paw ventilation used across the 4000 Series, engineered around real cooling efficiency rather than just a distinctive look through the wheel. Together, this construction is what makes the XS rotor a legitimate performance upgrade rather than a cosmetic drilled-and-slotted rotor. That's exactly the kind of thoughtful design DBA built its reputation on.

A Proper Direct Replacement, Not a Compromise

The unique drill and slot pattern is engineered specifically to clear gas and debris from the pad face while still maintaining the rotor's structural integrity, avoiding the premature cracking that a poorly designed drilled rotor can develop over time. As a direct-fit replacement, it bolts straight into place without any modification needed. It's the kind of rotor that looks aggressive because it's genuinely built to perform that way, not the other way around. For a component this critical, that level of engineering is worth having.

Straight From Subispeed

A genuinely high-performance drilled and slotted rotor for 2003-2012 WRX / 2004-2014 STI, built on real metallurgy and cooling technology rather than just an aggressive look.
