Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor features a vented design with pillar-style vanes that enhance airflow and cooling during braking. The rotor’s surface is both cross-drilled and slotted, which helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and reducing the risk of brake fade. The coated hat finish provides corrosion resistance, extending the rotor’s service life. With a floating disc mounting system, this rotor allows for slight movement to reduce stress and improve braking smoothness. The rotor measures 284.2 mm in outside diameter and has a nominal thickness of 22.0 mm, meeting the specifications required for Fiat 500 and Ram 700 models.

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Line

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to offer enhanced braking performance for street and light track use.
