About the ATE Original Rotor Product Line

The ATE Original Rotor line focuses on delivering rotors that maintain the integrity and performance standards expected by vehicle manufacturers. Designed with high-quality alloyed materials and precise engineering, the ATE Original Rotor 428197 ensures consistent braking performance and longevity for Porsche 911 vehicles. This product line emphasizes durability and compatibility with original equipment specifications.

Technical Details and Features

The ATE Original Rotor 428197 is constructed from alloyed high-carbon material, which provides a balance of strength and heat resistance essential for demanding braking conditions. The rotor features a directional disc finish that aids in channeling heat away from the braking surface, reducing the risk of warping. Its full cast construction is coated with a rust-resistant layer to protect against corrosion, extending the rotor's service life. The vented and drilled design enhances airflow, improving cooling efficiency during heavy braking. With a nominal thickness of 28.00 mm and a discard thickness of 26.00 mm, this rotor maintains structural integrity throughout its usable life. The rotor's dimensions and 5-bolt hole configuration ensure precise fitment on Porsche 911 models.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Porsche 911 vehicles
• Improves braking consistency and reduces brake fade under high stress
• Addresses corrosion issues with rust-resistant coating
• Enhances heat dissipation to prevent rotor cracking
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

When installing the ATE Original Rotor 428197 on a Porsche 911, ensure the rotor surface is clean and free of debris before mounting. Verify the rotor thickness is above the discard limit of 26.00 mm to maintain safety standards. Use the correct torque specifications for the 5-bolt pattern to secure the rotor properly. Note that this rotor does not include bearings or an ABS tone ring, so these components must be sourced separately if required. Proper bedding-in of the new rotor and brake pads is recommended to optimize braking performance.

Quality Assurance and Warranty

ATE Original Rotors are manufactured to meet strict quality standards, ensuring reliable performance and durability. The rust-resistant coating and high-carbon alloy material contribute to extended rotor life. While specific warranty details for part number 428197 should be confirmed with the supplier, ATE products typically come with manufacturer-backed warranties covering defects in materials and workmanship.
