ABS 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.

About this ABS replacement component
This ABS component is supplied as a cost-effective direct replacement for the corresponding Porsche OE reference. It is intended to retain the original disc or pad dimensions and work with the standard caliper and hydraulic system.
It is suited to routine road replacement where correct fitment and value are the main priorities. On cars used for frequent track driving, pad compound, disc temperature and inspection intervals should be selected to suit the intended use.
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.
