Product Features and Specifications

This StopTech rotor features a vented design with straight vanes to improve heat dissipation during braking. The cross-drilled surface reduces brake fade by allowing gases and debris to escape, enhancing overall rotor cooling. The coated hat finish helps protect against rust and corrosion, extending rotor life. With a center hole diameter of 68.1 mm and a mounting bolt hole circle diameter of 114.3 mm, this rotor is designed for precise fitment on Nissan 300ZX models. The floating disc mounting and two miscellaneous holes contribute to rotor stability and performance.
