The Porsche Cayman GT4 Clubsport Package utilized the same engine and manual gearbox as the standard model, featuring a de-tuned version of the 3.8-liter flat-six engine from the 911 (991) Carrera S. Suspension and brakes were also shared with the standard GT4. Notable enhancements in the Clubsport package included a rear half roll cage, provisions for a battery cut-off switch, a fire extinguisher, and a six-point racing harness compatible with a neck-saving HANS device for enhanced driver safety. It could also be equipped with the Sport Chrono Package, providing a unique Track Precision app and an additional ECU for transmitting telemetry data to the driver's smartphone.
