Designed to provide reliable stopping power and improved heat dissipation, this rotor is a solid choice for drivers seeking consistent brake response.

• Cross-drilled surface for improved heat dissipation and reduced brake fade
• Vented rotor design with pillar-style vanes for efficient cooling
• Coated hat finish to resist corrosion and extend rotor life
• Floating disc mounting for better rotor alignment and reduced stress
• Compatible with multiple Chrysler and Mercedes-Benz models including C230, CLK350, and SLK320

Detailed Product Features and Specifications

This StopTech rotor features a nominal thickness of 27.9 mm (1.098 inches) and a discard thickness of 25.4 mm (1.000 inch), ensuring it meets strict wear limits for safety and performance. The rotor’s outside diameter measures 300 mm (11.811 inches), with an overall height of 46.5 mm (1.831 inches). It includes a 5-lug hole pattern with a 112 mm (4.409 inch) bolt circle diameter and a center hole diameter of 67 mm (2.638 inches), designed to fit precisely on compatible vehicles.

The vented design incorporates pillar-style vanes that promote airflow to reduce heat buildup during braking. The cross-drilled surface pattern helps evacuate gases and debris, improving pad contact and braking consistency. The rotor’s floating disc mounting system allows slight movement to reduce stress and improve durability under demanding conditions.
