Designed specifically for models from 1987 to 1991, this rotor is a direct replacement that fits seamlessly with your vehicle's existing brake system. No need for complicated modifications—just swap out your old rotors and experience the difference.
Crafted from high carbon alloyed iron, these rotors are built to withstand the rigors of intense driving. Thanks to DBA's Thermal Stability Profiling, they can handle the heat and stress that comes with aggressive braking, ensuring consistent performance on every drive. Whether you're navigating city streets or tackling winding roads, these rotors are designed to keep you safe and in control.
One of the standout features of the DBA 4000 Series is its unique Kangaroo Paw ventilation system. With 144 diamond and teardrop patterned pillars, this design increases the surface area by up to 30% and improves cooling efficiency by 20% compared to traditional straight vane rotors. This means better heat dissipation and reduced brake fade, allowing you to push your BMW to its limits without worrying about performance drop-off.
When it comes to upgrading your BMW's braking system, DBA's 4000 Series Slotted Rotors offer a perfect balance of durability and performance. They not only enhance your vehicle's stopping power but also contribute to a smoother and more reliable driving experience.
