The zinc silver hat finish provides corrosion resistance, extending rotor life. This product line is tailored for drivers seeking reliable braking performance with enhanced heat management and durability.\u003c\/p\u003e\u003ch2\u003eDetailed Product Description\u003c\/h2\u003e\u003cp\u003eThis disc brake rotor features a vented design that promotes airflow to reduce heat buildup during braking, which helps maintain consistent stopping power. The drilled and slotted surface improves pad cleaning and gas evacuation, reducing brake fade. With a nominal thickness of 21.9 mm and a discard thickness of 20 mm, the rotor ensures safe replacement intervals. The zinc silver coating on the hat area offers rust resistance, preserving the rotor’s structural integrity over time. The rotor’s 5-bolt hole pattern with a 112 mm bolt circle diameter fits a range of Audi models including A4, A5, A6, A7, A8, S4, S5, and SQ5 variants, as well as Porsche Macan models.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCompatible with Audi A4, A4 allroad, A4 Quattro, A5, A5 Quattro, A5 Sportback, A6, A6 allroad, A6 Quattro, A7 Quattro, A7 Sportback, A8 Quattro, S4, S5, S5 Sportback, SQ5, SQ5 Sportback\u003c\/li\u003e\n\u003cli\u003eCompatible with Porsche Macan, Q5, Q5 PHEV, Q5 Sportback\u003c\/li\u003e\n\u003cli\u003eDesigned to address brake fade and overheating in performance and daily driving\u003c\/li\u003e\n\u003cli\u003eHelps reduce brake noise and vibration caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eImproves braking response and pad life by maintaining cleaner contact surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure rotor thickness is above discard thickness (20 mm) before installation\u003c\/li\u003e\n\u003cli\u003eUse proper torque specifications for the 5-bolt pattern with 112 mm bolt circle diameter\u003c\/li\u003e\n\u003cli\u003eClean rotor surface before installation to remove any protective coatings\u003c\/li\u003e\n\u003cli\u003eCheck compatibility with vehicle’s brake caliper and hub assembly\u003c\/li\u003e\n\u003cli\u003eIt is recommended to replace brake pads when installing new rotors for optimal performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the 631-73066L rotor to meet or exceed OEM specifications for fit, form, and function.
