• Compatible with Nissan 300ZX with 5 lug holes and 11.02 inch (279.9 mm) outside diameter
• Nominal thickness of 1.181 inches (30.0 mm) and discard thickness of 1.102 inches (28.0 mm)
• Overall height of 2.118 inches (53.8 mm) and center hole diameter of 2.681 inches (68.1 mm)

Detailed Product Description

This StopTech disc brake rotor, part number 227.42050L, is specifically designed for the Nissan 300ZX, ensuring precise fitment with a 5-lug hole pattern and a mounting bolt hole circle diameter of 4.5 inches (114.3 mm). The rotor features a vented design with straight vanes to optimize airflow and heat dissipation, reducing the risk of brake fade during demanding driving conditions. The cross-drilled and slotted surface improves pad bite and helps evacuate gases, dust, and water, maintaining consistent braking performance.

The floating disc mounting system allows for slight lateral movement, which helps prevent rotor warping and extends rotor life. With a nominal thickness of 1.181 inches (30.0 mm) and a discard thickness of 1.102 inches (28.0 mm), this rotor meets strict safety and performance standards. The overall height of 2.118 inches (53.8 mm) and center hole diameter of 2.681 inches (68.1 mm) ensure proper alignment and fitment on the Nissan 300ZX hub assembly.
