The DBA 5000 Series T3 two-piece front slotted rotor for 2004–2008 Porsche 911 GT3 pairs a cast iron ring with an aluminum hat to reduce weight and improve heat dissipation. Incorporating DBA's patented bi-directional T3 slot geometry, this direct-replacement rotor is engineered to manage heat and wear while lowering maintenance costs compared with one-piece race rotors.
