The StopTech Sport Cross-Drilled Disc Brake Rotors (Part Number 128.35058R) are engineered for precision braking performance on select Chrysler and Mercedes-Benz vehicles. Designed to enhance heat dissipation and reduce brake fade, these rotors provide reliable stopping power for models such as the Mercedes-Benz C230, CLK350, and Chrysler Crossfire.

• Cross-drilled surface for improved heat dissipation and gas venting
• Vented rotor design with pillar-style vanes for enhanced cooling
• Coated hat finish to resist corrosion and extend rotor life
• Floating disc mounting for better thermal expansion management
• Compatible with 5-lug wheel configurations and 112 mm bolt circle diameter

Detailed Product Specifications

This StopTech rotor features a nominal outside diameter of 300 mm (11.811 inches) and an overall height of 46.5 mm (1.831 inches), making it suitable for specific Chrysler and Mercedes-Benz models. The rotor is vented with pillar-style vanes to optimize airflow and cooling during braking. The cross-drilled surface pattern helps to reduce brake fade by allowing gases and heat to escape more efficiently. The hat section is coated to protect against rust and corrosion, ensuring durability over time.

The rotor has a nominal thickness of 27.9 mm (1.098 inches) with a discard thickness of 25.4 mm (1.000 inch), indicating when replacement is necessary. It mounts using a 5-stud lug pattern with a 112 mm (4.409 inch) bolt circle diameter and a center hole diameter of 67 mm (2.638 inches). This part does not include bearings or an ABS tone ring and weighs approximately 7.95 kg (17.5 lbs).
