Detailed Description

This ATE brake rotor is built for 2001-2003 Porsche 911 front left and 2004-2012 Porsche 911 front left applications. The SP34101 uses a vented, full cast design with a directional finish and coated surface to help maintain rotor condition in service. For Porsche 911 brake rotor replacement needs, this part is specified to meet or exceed OEM expectations in North America and is listed for vehicles that require a front left disc brake rotor with these dimensions.

This part cross-references Brembo 09.C877.11 for the same application.

What It Helps Address

• Brake pulsation caused by worn or uneven rotor surfaces
• Reduced braking consistency from rotor wear
• Surface corrosion on exposed brake rotor areas
• Noise related to rotor condition or finish irregularities
• Front axle braking service on Porsche 911 models

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and front left position before installation. Confirm the vehicle is equipped for a standard disc brake rotor and not ceramic composite brakes, since the listed fitment notes exclude ceramic composite brake applications. Always inspect pads, caliper condition, and hub surfaces during brake service to ensure proper rotor seating and braking performance.

Quality Assurance

ATE brake parts are backed by Continental Automotive Systems engineering and manufacturing experience. The brand supplies brake components to major vehicle producers and applies that OE-focused process knowledge to its aftermarket rotor line, including coated brake discs made with first-quality materials.
