Detailed Product Description

This DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is designed to meet the specific braking requirements of select BMW vehicles. The rotor’s vented construction allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to maintain consistent stopping power. The directional slotted and drilled surface improves water and debris evacuation, which can enhance braking response in wet or demanding conditions.

The rotor’s zinc silver hat finish provides corrosion resistance, extending the rotor’s service life, while the plain disc finish ensures smooth contact with brake pads. With a nominal thickness of 30 mm and a discard thickness of 28.4 mm, this rotor maintains structural integrity and performance throughout its lifespan. The 5-bolt hole pattern with a 120 mm bolt circle diameter ensures compatibility with the specified BMW models.

Compatible Vehicles and Applications

• Compatible with BMW 525i and 525xi models
• Fits BMW 528i, 528i xDrive, and 528xi variants
