Detailed Product Description

This Centric disc brake rotor features a solid design with a smooth surface type, optimized for standard braking applications on the Nissan 300ZX. The rotor's nominal thickness of 0.394 inches (10.000 mm) and discard thickness of 0.354 inches (9.000 mm) provide clear service limits for maintenance. The overall diameter of 11.417 inches (290 mm) and height of 1.850 inches (47.000 mm) ensure proper fitment and alignment with the vehicle's braking system. The floating disc mounting design allows for slight movement to reduce stress and improve rotor longevity.
