About this part

Product Details

This rear left brake rotor features a black electro-coating and a combination of drilled holes and slots. The drilled holes help dissipate heat and moisture, while the slots help sweep away dust and gas. This updated design helps maintain consistent braking performance, especially under demanding conditions. It's a solid option for your 2004-2007 BMW 525i, 2008-2010 BMW 528i, or 2004-2007 BMW 530i.

The rotor's construction uses a well-built iron alloy for durability. The black electro-coating not only gives it a clean look but also offers protection against rust and corrosion, which is especially important for the rotor surface that contacts the brake pads. This helps ensure the rotor stays looking good and performing well over time.
