Street Series Front Brake Rotor

The Stillen DBA540 brake rotor is a direct replacement component designed for the 1999-2004 Jeep Grand Cherokee (WJ). Manufactured by Disc Brakes Australia (DBA), these Street Series T2 Standard rotors are engineered to exceed OE standards, offering upgraded performance braking. They are cast from high carbon alloyed iron and treated with Thermal Stability Profiling (TSP) to withstand the increased stress and heat from demanding braking applications. Featuring a vented design, the DBA540 rotor utilizes DBA's patented Kangaroo Paw ventilation system, which incorporates 144 diamond and teardrop-shaped pillars. Key specifications for the DBA540 include a 305 mm outside diameter, a 72 mm center hole diameter, and a smooth surface finish. The rotor has a nominal thickness of 26 mm and a discard thickness of 26 mm, with an overall height of 64 mm and 5 stud/lug holes. Fitment details for the 1999-2004 Jeep Grand Cherokee are specific: For 1999-2001 models, compatibility depends on whether the vehicle has the Akebono Front Caliper (Cast #4802) or the ATE Front Caliper (Cast #4835). For 2002 models, it's crucial to note fitment before May 11, 2002 (Fr 5/11/02), as it can affect compatibility with either the Akebono or ATE front calipers.
