Eibach Pro-Tronic Cancellation Kit Porsche 991 GT3/RS & 981 Cayman GT4
The Eibach Pro-Tronic Cancellation Kit is made for Porsche 911 991 GT3/RS and Cayman 981 GT4 models with factory electronic damper control. When you fit performance dampers or coilovers without electronic adjustment, the car’s control units can trigger fault codes and dashboard warnings.
This kit works in the background to keep the electronics happy, so you can upgrade your suspension without annoying error messages. It is ideal when fitting Eibach B12, PSS, or similar coilover and damper setups.
Key benefits
- Prevents suspension-related warning lights after fitting non-electronic dampers
- Lets you run performance coilovers while keeping the car’s electronics stable
- Helps avoid constant fault messages on the dashboard
- Designed to integrate cleanly with the original vehicle systems
