DBA 08-13 BMW M3 E90/E92/E93 Rear 4000 Series Plain Rotor

If you're looking to replace the rear brake rotors on your 2008-2012 BMW M3, this 4000 Series HD rotor from DBA is a solid option. It's designed to handle the stresses of spirited driving while maintaining a clean, OE-style appearance. This rotor is built to keep your M3 stopping reliably, even when you push it a bit harder.

DBA casts these rotors from a high-carbon alloy iron, specifically XG-150, which is known for its ability to withstand the heat and stress that comes with frequent braking. They also undergo a process called Thermal Stability Profiling, which helps ensure the rotor's integrity under demanding conditions. What really sets these apart is the Kangaroo Paw ventilation system. Instead of traditional straight vanes, this design uses 144 diamond and teardrop-shaped pillars, increasing the surface area by up to 30% and improving cooling efficiency by 20% compared to standard rotors. This means better heat dissipation and more consistent braking performance when you need it most.

This particular rotor has a smooth, OE-style finish, making it a popular choice for drivers who want the performance benefits of DBA's 4000 Series without altering the factory look of their wheels. It's a direct replacement for your stock rear rotor, so installation should be straightforward.
