BMW Z4 Brake Rotor (1) - Front - DBA - 4000 Series T3 Slotted - `03-`06. This direct-replacement front rotor brings DBA’s 4000 Series T3 slot technology to your Z4, improving pad bite consistency and brake pedal feel for spirited street driving and occasional track use.

Built from XG-150 high carbon alloyed iron and finished with DBA’s Thermal Stability Profiling (TSP) and thermographic paint markings (THGP), this rotor is designed to resist heat fade and maintain structural integrity under repeated heavy braking. The T3 tri-symmetrical slot pattern increases exit points for pad dust and gases, yielding a more consistent contact surface and quieter operation compared with conventional slotted designs. Patented Kangaroo Paw ventilation with 144 diamond and teardrop pillars enhances cooling efficiency and surface area versus straight vane rotors, helping to manage temperatures during demanding use.
