The drilled and slotted design helps reduce brake fade by allowing gases and debris to escape, while the zinc silver coating on the hat provides corrosion resistance to extend rotor life.\u003c\/p\u003e\u003ch2\u003eTechnical Description and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a 330 mm outside diameter and a discard thickness of 18.4 mm, ensuring compatibility with specific BMW and Toyota vehicles. The rotor surface is both drilled and slotted in a directional pattern, which improves water and dust evacuation from the braking surface. The plain disc finish combined with a zinc silver rust-resistant coating on the hat enhances durability and corrosion resistance, making it suitable for various driving conditions.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatible with BMW 230i, 230i xDrive, 330e, 330e xDrive, 330i, 330i xDrive, 430i, 430i Gran Coupe, 430i xDrive, 430i xDrive Gran Coupe, 530e, 530e xDrive, 530i, 530i xDrive, iX3, X3, X4, and Z4 models\u003c\/li\u003e\n\u003cli\u003eCompatible with Toyota GR Supra\u003c\/li\u003e\n\u003cli\u003eDesigned for use in disc brake systems requiring directional drilled and slotted rotors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Issues Addressed by This Rotor\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake fade caused by excessive heat buildup during aggressive driving\u003c\/li\u003e\n\u003cli\u003eCorrosion and rust on rotor hats reducing rotor lifespan\u003c\/li\u003e\n\u003cli\u003ePoor water and debris evacuation leading to inconsistent braking\u003c\/li\u003e\n\u003cli\u003eUneven brake pad wear due to inefficient rotor surface design\u003c\/li\u003e\n\u003cli\u003eReduced braking performance in wet or dusty conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation direction. Verify that the discard thickness of 18.4 mm is not exceeded during rotor replacement. Clean the rotor surface before installation to remove any protective coatings or contaminants.
