Hella Pagid - High Carbon and Fully Coated Product Line

This rotor is part of the Hella Pagid - High Carbon and Fully Coated line, which focuses on enhanced wear resistance and corrosion protection. The fully coated surface treatment extends the rotor's lifespan by reducing rust formation, while the high carbon content in the gray cast iron improves thermal conductivity and braking stability. This combination is particularly beneficial for BMW vehicles that demand consistent braking performance under varied driving conditions.

Detailed Product Description

The Pagid disc brake rotor 355122082 is constructed from gray cast iron, a material known for its excellent heat dissipation and durability under braking stress. The rotor features a vented design, which allows air to circulate between the rotor surfaces, reducing heat buildup and minimizing brake fade during extended use. Both the disc and hat surfaces are coated to resist rust and corrosion, maintaining rotor integrity and appearance over time. With a nominal thickness of 29.90 mm and a discard thickness of 28.40 mm, this rotor provides clear guidelines for maintenance and replacement to ensure safety. The 7-bolt hole configuration and 324 mm outside diameter are tailored to fit specific BMW models, ensuring proper installation and performance.
