Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor is specifically designed for the Nissan 300ZX, providing a direct replacement that meets OEM specifications. The vented rotor design features straight vanes that enhance airflow, helping to dissipate heat generated during braking. The cross-drilled and slotted surface improves pad bite and helps evacuate gases, dust, and water, which can accumulate during aggressive driving or wet conditions. The coated hat finish protects the rotor from rust and corrosion, maintaining structural integrity and appearance over time.

With a mounting bolt hole circle diameter of 4.055 inches (103 mm) and four mounting holes, this rotor installs behind the hub, matching the factory setup. The nominal thickness of 0.866 inches (22 mm) ensures durability, while the discard thickness of 0.787 inches (20 mm) provides a clear wear limit for safety and maintenance.
