This design improves water and gas evacuation during braking, reducing fade and maintaining consistent performance. The silver zinc coating on the rotor hat provides corrosion resistance, extending the rotor's service life. This rotor line is tailored for drivers seeking reliable braking components with enhanced heat management.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications and Features\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor is a solid type with a 272 mm outside diameter and an overall height of 83.2 mm. It features a nominal thickness of 10 mm and a discard thickness of 8.4 mm, ensuring clear service limits for safe operation. The rotor includes five bolt holes, each 14.6 mm in diameter, arranged on a 120 mm bolt circle diameter, matching the BMW Z3's hub specifications. The center hole diameter is 75 mm, and the rotor surface is directional with both drilled holes and slots to improve braking efficiency and heat dissipation. The rotor hat is finished in zinc silver with a rust-resistant coating to protect against corrosion.\u003c\/p\u003e\u003ch2\u003eApplications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement rotor for worn or warped BMW Z3 brake rotors\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during spirited driving\u003c\/li\u003e\n\u003cli\u003eEnhances water and debris evacuation for consistent braking in wet conditions\u003c\/li\u003e\n\u003cli\u003eRestores braking performance compromised by rotor surface damage\u003c\/li\u003e\n\u003cli\u003eProvides corrosion resistance to extend rotor lifespan\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor thickness is above the discard thickness of 8.4 mm before installation. Clean the rotor surface to remove any protective coating residue before mounting. Verify bolt hole alignment with the BMW Z3 hub using the 5-bolt, 120 mm bolt circle pattern. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-31045R rotor to meet OEM specifications for the BMW Z3.
