Description
Genuine Porsche Rear Brake Discs 350x28mm – Porsche 997 GT3 is a direct-replacement rear brake disc for the listed Porsche GT applications. It is intended for vehicles using the stated steel brakes system and retains the original mounting arrangement, caliper position and brake balance.
Brake discs on Porsche GT models are highly application-specific. Diameter alone is not enough to confirm compatibility: disc thickness, offset, bell depth, handed orientation, brake option and production date must also match.

Why choose Genuine Porsche?
Genuine Porsche braking components are produced to the original vehicle specification, including the correct dimensions, material specification, mounting geometry and compatibility with the factory caliper and electronic wear-monitoring system.
They are the preferred choice where maintaining the original braking feel, fit, finish and Porsche parts traceability is the priority. Genuine parts are especially valuable on GT and RS models where different model years, brake options and transmission variants can use visually similar but incompatible components.
Always match the Porsche part number against the vehicle VIN or the part removed from the car before ordering.
Installation and compatibility notes
- Confirm compatibility by VIN, original Porsche part number or the number on the component removed from the vehicle.
- Check whether the car is fitted with conventional steel brakes or Porsche Ceramic Composite Brakes.
- Inspect the caliper, pad retaining hardware, brake hoses and wear sensors while the brake system is dismantled.
- Brake discs must be installed onto clean, corrosion-free hub faces and checked for runout before the vehicle is returned to service.
- New pads and discs require the correct bedding procedure. Avoid prolonged stationary brake application immediately after heavy braking.
- Professional installation is strongly recommended on all GT and RS braking systems.
