Detailed Product Description

This Centric C-TEK Standard Disc Brake Rotor 121.42902 is specifically designed for the Nissan 300ZX, featuring a vented rotor construction with 36 straight vanes that promote efficient heat dissipation during braking. The rotor’s overall diameter of 250 mm and nominal thickness of 22 mm ensure compatibility with factory specifications, maintaining proper braking performance and safety. The smooth surface type provides consistent friction against brake pads, reducing uneven wear and noise. With four mounting bolt holes arranged on a 103 mm bolt circle diameter, installation aligns precisely behind the hub, matching OEM fitment requirements. The discard thickness of 20 mm serves as a critical indicator for rotor replacement to maintain optimal braking efficiency.
