Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor is designed specifically for the BMW X5, providing a precise fit and reliable braking performance. The rotor features a vented construction with straight vanes that improve airflow and heat dissipation during braking. The cross-drilled and slotted surface pattern helps to reduce brake fade by allowing gases and debris to escape, while also improving pad bite and wet weather performance.

The rotor’s coated hat finish offers protection against corrosion, extending the service life of the part. With a floating disc mounting design, this rotor accommodates thermal expansion and reduces the risk of warping under high-stress conditions. The rotor measures 356 mm in outside diameter and has a nominal thickness of 36 mm, with a discard thickness of 34.4 mm, ensuring it meets OEM specifications for durability and safety.
