This product line is designed for solid rotors with a coated hat finish to reduce corrosion, making them suitable for both street and light performance driving. The 128.35034R rotor maintains strict OEM specifications for fitment and dimensions, ensuring compatibility and reliable operation on various Mercedes-Benz vehicles.

Technical Specifications and Features

These rotors feature a solid disc design with cross-drilled holes to improve cooling efficiency during braking. The coated hat finish protects against rust and corrosion, extending the rotor's service life. With a nominal thickness of 0.394 inches (10.000 mm) and a discard thickness of 0.327 inches (8.300 mm), these rotors meet strict wear limits for safety and performance. The overall diameter of 11.417 inches (290.000 mm) and height of 2.177 inches (55.300 mm) ensure proper fitment on compatible Mercedes-Benz models. The rotor includes five lug holes with a 4.409 inch (112.000 mm) bolt circle diameter and a center hole diameter of 2.638 inches (67.000 mm), matching OEM mounting requirements.

Applications and Problem Solving

• Restores braking performance on Mercedes-Benz C-Class, CLK, E-Class, and SLK models
• Reduces brake fade caused by excessive heat buildup during aggressive driving
• Improves brake pad bite and response with cross-drilled surface design
• Prevents corrosion-related rotor damage with coated hat finish
• Addresses rotor wear and thickness below OEM discard limits

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.327 inches) before installation
• Clean mounting surfaces and check for proper bolt torque on the 5 lug holes
• Verify compatibility with ABS systems as this rotor does not include an ABS tone ring
• Inspect brake pads and calipers for wear or damage during rotor replacement
• Follow manufacturer torque specifications for mounting bolts to avoid warping
