Detailed Product Description

This disc brake rotor is specifically designed for the Nissan 300ZX, providing a precise fit and reliable braking performance. The rotor features a vented design with straight vanes that help dissipate heat more efficiently during braking, reducing the risk of brake fade. The cross-drilled and slotted surface improves pad bite and helps evacuate gases, dust, and water from the rotor surface, maintaining consistent braking power in various driving conditions.

The rotor’s coated hat finish offers protection against corrosion, extending the rotor’s service life. With a nominal thickness of 0.709 inches (18.000 mm) and a discard thickness of 0.630 inches (16.000 mm), this rotor meets strict specifications to ensure safety and performance.
