Stoptech 127.35058L Disc Brake Rotor - Front Left

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Overview

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors (Part Number 127.35058L) are engineered for enhanced braking performance on select Chrysler and Mercedes-Benz vehicles. Designed to improve heat dissipation and reduce brake fade, these rotors are an ideal upgrade for models such as the Mercedes-Benz C230, CLK350, and Chrysler Crossfire.

• Cross-drilled and slotted surface for improved cooling and debris removal
• Vented rotor design with pillar-style vanes for efficient heat dissipation
• 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 Features and Specifications

This disc brake rotor features a nominal outside diameter of 300 mm (11.811 inches) and an overall height of 46.5 mm (1.831 inches), providing a precise fit for compatible vehicles. The rotor thickness ranges from a nominal 27.9 mm (1.098 inches) down to a discard thickness of 25.4 mm (1.000 inch), ensuring clear service limits for maintenance. The vented design incorporates pillar-style vanes that promote airflow to reduce heat buildup during braking. The rotor surface is cross-drilled and slotted, which helps evacuate gases, dust, and water, improving braking consistency under demanding conditions. The hat section is coated to protect against rust and corrosion, maintaining structural integrity over time. This rotor does not include ABS tone rings or bearings and is designed for floating disc mounting, which allows for slight movement to accommodate thermal expansion and reduce stress.
