Detailed Product Description

The StopTech Sport Slotted Disc Brake Rotors are designed to meet the rigorous demands of performance-oriented Mercedes-Benz vehicles such as the ML55 AMG, ML430, and ML500. This rotor features a vented design with curved vanes that promote superior airflow, helping to dissipate heat more effectively during heavy braking. The slotted surface improves pad bite and helps channel away dust and gases, reducing brake fade and maintaining consistent braking performance.

With a coated hat finish, the rotor resists corrosion, extending its service life. The floating disc mounting system allows for slight movement between the rotor and hub, which helps maintain better alignment and reduces the risk of warping. The rotor measures 345 mm in outside diameter and has a nominal thickness of 32 mm, with a discard thickness of 30 mm, ensuring it meets strict OEM specifications for fit and function.
