Detailed Product Description

This StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor (127.34060R) is designed specifically for BMW X5 vehicles. The rotor measures 356 mm in outside diameter and 62.3 mm in overall height, with a nominal thickness of 36.0 mm. Its vented construction with straight vanes promotes efficient airflow to reduce heat during braking, which helps prevent brake fade. The cross-drilled and slotted surface improves water and gas evacuation from the rotor surface, enhancing brake pad contact and performance in wet or high-temperature conditions.

The rotor’s hat is coated to protect against corrosion, ensuring durability over time. It features a floating disc mounting system that allows slight movement between the rotor and hub, reducing stress and improving braking consistency. The rotor includes five lug holes with a 120 mm bolt circle diameter, matching the BMW X5’s wheel hub specifications. This rotor does not include ABS tone rings or bearings.
