DBA 4000 Series T3 Front Slotted Brake Rotor for Porsche 911/Boxster/Cayman 1997-2011 (3.4L)

Fits select 1997-2011 Porsche 911, Boxster, and Cayman (3.4L).

The DBA 4000 Series T3 is a high-performance, direct-replacement single-piece brake rotor designed for drivers seeking superior heat management and braking consistency. Engineered for track days and spirited street driving, these rotors utilize XG150 high carbon alloyed iron and Thermal Stability Profiling (TSP) to handle extreme thermal stress without warping or cracking.

The T3 slot design features 48 tri-symmetrical curved slots that significantly reduce vibration and provide a quieter, smoother brake pedal feel while constantly clearing dust and gases from the pad surface. This rotor also incorporates DBA’s patented Kangaroo Paw ventilation system, which uses a series of 144 diamond and teardrop-shaped pillars to increase surface area and improve cooling efficiency over standard straight-vane designs.
