The DBA 4000 Series T3 slotted rotor for 2003–2006 BMW Z4 2.5i front applications is a direct-replacement single-piece rotor using high-carbon, heat-treated iron combined with DBA’s Kangaroo Paw ventilation and T3 bi-directional slotting. That slot geometry and the tri-symmetrical pattern help clear gas and debris for consistent pad contact and braking response, while the rotor keeps OE-style fitment for straightforward installation.
