Product Line Overview: StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line is designed for drivers seeking enhanced braking performance with improved thermal management. The cross-drilled surface pattern helps to dissipate heat and gases generated during braking, while the vented rotor design promotes airflow to reduce fade. This rotor line features a coated hat finish to resist corrosion and a floating disc mounting system that allows for better rotor alignment and reduced stress on the braking components. The 128.42046R rotor is a part of this line, tailored specifically for Nissan 300ZX applications.

Detailed Product Description

This disc brake rotor features a vented design with straight vanes that facilitate efficient cooling during braking. The cross-drilled surface improves water and gas evacuation, which helps maintain consistent brake pad contact and reduces the risk of brake fade. The rotor’s overall height measures 54 mm (2.126 inches), and it includes two miscellaneous holes for mounting or alignment purposes. The center hole diameter is 68.1 mm (2.681 inches), and the rotor is designed with a floating disc mounting system to accommodate thermal expansion and improve braking stability. The coated hat finish protects the rotor from rust and corrosion, extending its service life.

Common Applications and Problem Solving
