Detailed Description

ATE SP24176 is engineered as a rear brake rotor for 1999-2008 Porsche 911 models, with fitment covering 1999-2005 Porsche 911 rear and 2005-2008 Porsche 911 rear. It meets or exceeds OEM specifications for North American applications, and the fitment notes specify that the 2005-2008 Porsche 911 rear application is not suitable for ceramic composite brakes. If you are replacing worn rear rotors on a Porsche 911, SP24176 provides the dimensions and vented design needed for a proper OE-style service replacement.

This part cross-references Brembo 09.6665.11 and Raybestos Brakes 96962 for the same application.

What This Rotor Helps Address

• Brake pulsation caused by rotor wear or thickness variation
• Reduced braking consistency from heat-stressed rear rotors
• Corrosion on exposed rotor surfaces
• Noise or vibration related to uneven rotor condition
• Service replacement needs for Porsche 911 rear brake maintenance

Installation Notes and Tips

Verify rear axle fitment by year and brake system before installation. Confirm that the vehicle is not equipped with ceramic composite brakes when servicing 2005-2008 Porsche 911 rear applications. Clean the hub mounting surface, inspect pads and calipers, and follow the vehicle manufacturer’s torque and bedding procedures after installation.

Quality Assurance

ATE brake parts are backed by Continental Automotive Systems’ OE brake engineering experience, with product development informed by original equipment manufacturing standards. The coated rotor design reflects ATE’s focus on premium materials and corrosion protection for aftermarket brake service.
