The DBA 4000 Series High Performance Brake Rotor is engineered with advanced metallurgy, utilizing XG-150 high carbon alloyed iron to withstand intense braking conditions and thermal stress. Undergoing Thermal Stability Profiling, this rotor maintains consistent performance under high heat, making it ideal for demanding driving environments. The rotor features DBA’s patented Kangaroo Paw ventilation system, consisting of 144 diamond and teardrop-shaped pillars designed to increase surface area by up to 30% and improve cooling efficiency by 20% over traditional straight vane designs. This innovative design helps reduce brake fade, extend rotor life, and enhance overall braking performance. The smooth OE-style finish offers a clean, factory appearance, suitable for drivers seeking a performance upgrade without sacrificing a stock look, particularly in controlled race or street applications. This rotor is a direct replacement for OEM parts on compatible BMW 325 models from 1986 to 1987, ensuring a hassle-free upgrade with precise fitment and performance benefits. Constructed from durable, moisture-proof materials, it is packaged to resist corrosion and ready for installation. Whether you are upgrading your vehicle for spirited driving or regular highway use, the DBA 4000 Series rotor provides reliable, high-performance braking with a focus on thermal management and longevity.
