Pagid 355126921 Disc Brake Rotor - Front Left

Pagid Front Left Drilled Brake Rotor

The Pagid 355126921 is a front left disc brake rotor built for select Porsche applications, including the 2012-2016 Porsche 911 and 2016 Porsche Boxster. It uses a high-carbon gray cast iron construction with a coated finish to support corrosion resistance and consistent braking performance.

Part of the Hella Pagid High Carbon and Fully Coated line, this rotor combines a drilled, internally vented design with a directional brake surface for controlled heat management and OE-style replacement fitment. The Pagid 355126921 is a direct-fit brake rotor for drivers replacing a worn or damaged front rotor on compatible Porsche 911 and Porsche Boxster models.

Product Details

This rotor is engineered with a full cast construction, mill balancing, and a perforated/vented braking surface to support stable braking under repeated use. The 34 mm nominal thickness and 32 mm minimum thickness provide the dimensional range needed for service replacement, while the 98 mm centering diameter and 69.5 mm overall height match the listed fitment requirements. The Hella Pagid High Carbon and Fully Coated product line focuses on coated rotor surfaces and high-carbon material selection for corrosion resistance and consistent rotor performance. This part cross-references Monroe Shocks & Struts 172939 for the same application.

Common Problems This Rotor Can Address

• Brake pulsation from a worn or uneven front rotor
• Reduced braking consistency caused by rotor wear beyond minimum thickness
• Surface corrosion on the braking face or hat area
• Noise or vibration associated with damaged rotor surfaces
• Service replacement needs on select Porsche 911 and Porsche Boxster front left positions

Installation Notes and Fitment

Fits 2012-2016 Porsche 911, front left. Fits 2016 Porsche 911, front left. Fits 2016 Porsche Boxster, front left. Not compatible with vehicles equipped with ceramic composite brakes.
