Detailed Product Description

The StopTech Sport Cross-Drilled Disc Brake Rotors are specifically designed for select Mercedes-Benz SUVs including the ML320, ML350, and ML430. This rotor features a vented design with straight vanes that promote efficient airflow to reduce heat buildup during braking. The cross-drilled surface helps to dissipate gases and water, improving brake pad contact and reducing fade under demanding conditions. The rotor’s hat is coated to protect against corrosion, extending the service life of the part. With a floating disc mounting, the rotor accommodates thermal expansion and contraction, maintaining consistent braking performance.

Key dimensions include an outside diameter of 303 mm (11.929 inches), nominal thickness of 26 mm (1.024 inches), and discard thickness of 23 mm (0.906 inches). The rotor mounts with five lug holes on a 112 mm bolt circle diameter, matching the factory specifications for the listed Mercedes-Benz models. The center hole diameter is 67 mm (2.638 inches), ensuring proper fitment and alignment.
