Product Line Details: Hella Pagid OE Two Piece Design

This rotor is part of the Hella Pagid - OE Two Piece Design Made in Europe (Aluminum Hat, High Carbon Friction Ring, Fully Coated) product line. Featuring a composite construction with a high carbon friction ring and aluminum hat, this design improves thermal management and reduces unsprung weight. The fully coated surfaces provide enhanced corrosion resistance, extending the rotor's service life under demanding conditions.

Technical Description and Fitment

The Pagid 355120691 disc brake rotor is a vented, composite rotor constructed from gray cast iron paired with an aluminum hat. The vented design promotes efficient heat dissipation, reducing the risk of brake fade during extended use. The rotor’s coated finish on both the disc and hat surfaces offers protection against rust and corrosion, which is critical for maintaining consistent braking performance over time. With a 374 mm outside diameter and 6 bolt holes, this rotor is compatible with BMW 550i GT, 550i GT xDrive, 750i, 750i xDrive, 750Li, and 750Li xDrive models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on BMW 550i GT and 750Li models
• Improves braking consistency by reducing heat-related fade
• Addresses corrosion issues with coated surfaces
• Restores proper rotor thickness for safe braking performance
• Compatible upgrade for vented rotor systems requiring composite construction

Installation Notes and Tips

Ensure the rotor discard thickness of 34.40 mm is not exceeded before installation. Properly torque the 6 bolt holes to manufacturer specifications to avoid rotor warping. It is recommended to inspect brake pads and hardware during rotor replacement to maintain optimal braking system performance. The composite design requires careful handling to avoid damage to the aluminum hat.

Quality Assurance and Warranty

Pagid rotors are manufactured to meet OE standards, with quality controls in place to ensure dimensional accuracy and material integrity. The rust-resistant coating extends rotor life in various driving conditions. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
