This design aids in reducing brake fade by improving heat dissipation and helps channel away water and brake dust. The zinc silver hat finish provides corrosion resistance, extending rotor life especially in environments prone to rust. This rotor line is tailored for vehicles requiring reliable vented rotors with directional braking surfaces.\u003c\/p\u003e\u003ch2\u003eTechnical Description and Specifications\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is vented, allowing air to flow between the rotor faces to reduce heat buildup during braking. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18.4 mm, indicating when replacement is necessary. The rotor surface is both drilled and slotted, which helps maintain consistent braking performance by removing gases and debris from the pad interface. The rotor’s overall diameter is 330 mm, with a height of 69.1 mm, ensuring compatibility with specified BMW 5 Series models. The zinc silver hat finish and rust-resistant coating protect against corrosion, maintaining structural integrity over time.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Common Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for BMW 528i and 528i xDrive models\u003c\/li\u003e\n\u003cli\u003eSuitable for BMW 535d and 535d xDrive variants\u003c\/li\u003e\n\u003cli\u003eFits BMW 535i and 535i xDrive vehicles\u003c\/li\u003e\n\u003cli\u003eCompatible with BMW ActiveHybrid 5\u003c\/li\u003e\n\u003cli\u003eIdeal for addressing brake fade, rotor warping, and uneven pad wear\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed on the correct side as it features a directional braking surface. Verify bolt hole alignment with the 5-lug, 120 mm bolt circle diameter pattern. Clean the rotor surface before installation to remove any protective coatings or residues. Check the discard thickness of 18.4 mm regularly to determine rotor replacement timing. Proper torque specifications should be followed for the 16.6 mm bolt holes to avoid rotor damage.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction rotors undergo rigorous quality control to meet OEM standards for fitment and performance. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion resistance.
