JRZ RS PRO Coilovers Porsche Cayman GT4 / GT4RS 718 — triple-adjustable motorsport damping built to order in the Netherlands by JRZ Suspension Engineering. Every unit is hand-assembled and dyno-validated before shipping. Browse all JRZ coilovers.
The JRZ RS PRO Coilovers Porsche Cayman GT4 GT4RS 718 deliver motorsport-grade double-adjustable damping with independent compression and rebound control in a remote reservoir mono-tube design. Built by JRZ Suspension Engineering in the Netherlands, the RS PRO gives GT4 and GT4 RS owners precise two-way tuning with the thermal capacity of a full mono-tube reservoir system. For different adjustability levels, see the 11 Series, 12 Series, or RS TWO.
The RS PRO sits between the simplicity of the RS TWO and the full tunability of the 12 Series. Two independent adjustments — compression and rebound — give you meaningful control over damper behaviour without the complexity of separating high-speed and low-speed compression. The remote reservoir mono-tube design provides superior heat dissipation for sustained hard driving.
Every JRZ RS PRO kit for the Porsche 718 Cayman GT4 is hand-assembled at JRZ’s facility in the Netherlands. Damper bodies are machined from aerospace-grade aluminium, valving is set to Meisterschaft specifications, and each unit is dyno-verified before shipping. Front camber plates (JRZ p/n 99 001 991 4) and rear top mounts (JRZ p/n 99 001 981 4) are included and engineered specifically for the 718 GT4 chassis.
Designed as a direct bolt-in for the Porsche 718 Cayman GT4 and GT4 RS (2017–2025). The kit includes front and rear dampers with remote reservoirs, JRZ adjustable camber plates up front, JRZ rear top mounts, and your choice of spring package. Springs are available in Street, Street/Track Hybrid, Track, or Custom rates — chosen based on your driving style, tire compound, and whether the car sees daily use, track days, or dedicated competition. Every kit is a direct bolt-in with no fabrication required.
