Detailed Product Description

This Centric C-TEK Standard Disc Brake Rotor, part number 121.42046, is specifically designed for Nissan 300ZX models requiring a vented rotor with a smooth braking surface. The vented design features straight vanes that promote effective heat dissipation, reducing the risk of brake fade during extended use. The rotor’s nominal thickness of 1.028 inches (26.1 mm) ensures durability, while the discard thickness of 0.945 inches (24 mm) provides a clear wear limit for safe replacement. The floating disc mounting system allows for slight rotor movement, which helps maintain even pad contact and consistent braking performance. With a 5-lug hole pattern and a 4.5 inch (114.3 mm) bolt circle diameter, this rotor fits securely on the Nissan 300ZX hub assembly.
