• Nominal thickness: 30.00 mm; discard thickness: 28.40 mm
• Outside diameter: 348.00 mm; height: 73.20 mm
• Vented rotor construction for improved heat dissipation
• Fully coated disc and hat surfaces with rust-resistant finish
• Composite two-piece design with 6 bolt holes

Detailed Product Features and Construction

This disc brake rotor features a composite construction combining a high carbon gray cast iron friction ring with an aluminum hat, reducing unsprung weight while maintaining strength. The vented design enhances cooling during braking, helping to prevent fade under demanding conditions. Both the disc and hat are fully coated with a rust-resistant finish to extend service life and reduce corrosion. The rotor measures 348 mm in outside diameter and 73.20 mm in height, with a nominal thickness of 30.00 mm and a discard thickness of 28.40 mm, ensuring precise fitment and performance for BMW Z4 vehicles. The 6-bolt hole pattern matches OEM specifications for secure installation.

About the 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. This line focuses on delivering OE-level quality through a two-piece composite design that combines a lightweight aluminum hat with a high carbon friction ring. The fully coated surfaces provide enhanced corrosion resistance, making these rotors suitable for European vehicles like the BMW Z4 that demand precise engineering and durability.

Applications and Problem Solving

• Replacement for worn or warped rotors on BMW Z4 models
• Addresses brake fade caused by overheating through vented design
• Prevents rust and corrosion on braking surfaces and mounting areas
• Improves braking consistency with high carbon friction material
• Reduces unsprung weight for better vehicle handling

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 28.40 mm before installation. Clean mounting surfaces thoroughly to prevent uneven rotor seating. Use the correct torque specifications for the 6-bolt pattern to avoid warping. It is recommended to replace brake pads simultaneously to maintain optimal braking performance.

Quality Assurance and Warranty

Pagid rotors are manufactured to meet or exceed OEM standards, with strict quality control processes in place. The rust-resistant coating and composite construction contribute to long service life. Warranty coverage details should be confirmed with the point of purchase or manufacturer documentation.
