Product Line Details

DFC GEOSPEC rotors are engineered with a corrosion-resistant coating and tight machining tolerances to match OEM expectations for fit and finish.

Together, the two product lines create a service kit focused on consistent braking feel and reduced installation prep.

Detailed Description

Part number 4504-31073 is a brake service kit for 2020 BMW X5 and BMW X6 models, plus 2017-2019 BMW 540i and 540i xDrive applications listed with standard brakes. It also covers the noted original design aluminum hat rotor and optional design full cast rotor configurations. The coated rotors are processed dry and machined to OE specifications, while the pads are assembled with NVH-focused shims for smoother operation. This makes the kit a practical choice for BMW X5, BMW X6, and BMW 540i brake maintenance when replacing worn rotors and pads together.

What This Kit Helps Address

• Brake pulsation from worn or uneven rotors
• Rust buildup on exposed rotor surfaces
• Noise during braking from aged pads or hardware wear patterns
• Longer stopping distances caused by depleted friction material
• Uneven pad bed-in after a brake service

Installation Notes

Install as a complete axle service on the listed front and rear applications. The rotors are shipped dry and ready to install, which reduces prep time during brake work. For best results, follow the vehicle manufacturer’s service procedure and perform a proper pad bed-in after installation.
