Front Brake Rotor

The Stillen DBA4418 brake rotor is part of DBA's 4000 Series HD line, offering enhanced performance braking beyond standard OE levels. These rotors are engineered as a direct, single-piece replacement, ensuring compatibility for drivers looking to upgrade their braking system. The rotor is constructed from XG-150 high carbon alloyed iron, which provides increased thermal capacity to withstand extreme heat generated during intense braking applications. This advanced metallurgy, combined with DBA's Thermal Stability Profiling (TSP) process, helps stabilize natural rotor stresses by realigning the iron's microstructure, thereby minimizing warping and cracking and prolonging the rotor's service life. The 4000 Series HD variant features an OE-style smooth finish, appealing to those who prefer a more conventional aesthetic while still demanding superior performance, such as in controlled race divisions. This rotor incorporates DBA’s patented Kangaroo Paw ventilation system, which utilizes 144 diamond and teardrop-shaped pillars. This design significantly increases surface area, leading to up to a 30% improvement in cooling efficiency compared to traditional straight vane designs. This enhanced cooling minimizes brake fade and increases overall braking effectiveness, while also extending the service life of both pads and rotors. Thermo-graphic paint markings (THGP) are included, changing color at specific temperature thresholds to clearly indicate peak braking temperatures, aiding in rotor fatigue monitoring and warranty claims. This specific DBA4418 rotor is designed for the front of the 2003-2006 Mitsubishi Lancer Evolution models. It is crucial to note that front and rear discs are different, and discs are sold individually, requiring the purchase of two for a complete pair.
