Rear Brake Rotor w/ Kangaroo Paw Ventilation

The Stillen DBA2439S is a rear brake rotor from DBA Brakes, engineered for drivers seeking enhanced braking performance beyond standard OE levels. This rotor is constructed from high-carbon alloyed iron that has been subjected to Thermal Stability Profiling (TSP). This process ensures the material can consistently handle the elevated stress and heat generated during demanding braking applications. The design incorporates DBA's proprietary Kangaroo Paw ventilation system, which utilizes 144 diamond and teardrop-shaped pillars. This unique ventilation structure provides up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs, contributing to superior heat dissipation and consistent performance. This DBA Street Series T2 rotor features a slotted surface type and a vented construction, with a nominal and discard thickness of 22 mm. Its outside diameter is 320 mm and its overall height is 67.25 mm, with a center hole diameter of 72.6 mm and 5 lug holes. The DBA2439S is specifically designed as a direct replacement for various Chrysler 300, Dodge Challenger, Dodge Charger, and Dodge Magnum models from select model years. Fitment can be highly specific, with notes indicating compatibility variations based on trim levels, specific brake packages (e.g., Hemi, R/T, SRT8, Mopar BBK), caliper piston counts, and front disc sizes. For example, certain Chrysler 300 models require Hemi engines and vented rear discs, while specific Dodge Charger applications may be excluded from Police or SRT8 packages or depend on specific front caliper and disc dimensions. It is crucial to verify application details against the detailed fitment notes provided.
