Sebro Front Brake Discs 380x34mm – Porsche 981/718 Cayman GT4 is a direct-replacement front 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 Sebro
Sebro manufactures direct-replacement brake discs for European performance vehicles. These discs are designed around the original Porsche dimensions and mounting arrangement, making them a suitable option for owners who want an OE-style replacement without changing the factory caliper, pads or brake balance.
Correct machining, ventilation and friction-ring geometry are important on Porsche GT applications because the brake system is exposed to high thermal loads. The disc should always be installed with clean hub faces, correctly torqued wheels and a controlled bedding procedure.
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.
