JRZ RS ONE single adjustable damper for the Porsche Cayman GT4 981 (2015-2017). Designed for street driving with track-day capability, featuring 21 precise clicks of combined compression and rebound adjustment. CNC-machined internals deliver refined ride quality on the street without sacrificing control at the track. Built to order through Meisterschaft Motorsport Engineering, the official U.S. importer of JRZ Suspension. Every set includes expert setup consultation for your Porsche.

The JRZ RS ONE Coilovers Porsche Cayman GT4 981 deliver motorsport-grade single-adjustable damping with rebound control in a remote reservoir mono-tube design. Built by JRZ Suspension Engineering in the Netherlands, the RS ONE gives 981 GT4 owners a streamlined entry into JRZ’s racing-derived damping technology. For more adjustability, see the RS TWO, 11 Series, or 12 Series.

WHY THE RS ONE EXISTS

The RS ONE distils JRZ’s motorsport damping technology into its most accessible form. A single rebound adjustment gives you meaningful control over body motion and weight transfer without the complexity of multi-way tuning — ideal for drivers who want proven performance with a straightforward setup process.

  • Single-adjustable rebound — one knob dials in body control and transient response without overcomplicating setup
  • Remote reservoir mono-tube — increased oil volume means better heat dissipation and consistent damping over long sessions
  • Meisterschaft-spec valving — tuned specifically for 981 GT4 mass, spring rates, and chassis dynamics
Not sure which series?
The RS ONE is JRZ’s entry-level damper — single-adjustable rebound with a monotube, remote-reservoir design. Step up to the RS TWO for double-adjustable control, or the RS PRO for a monotube with external reservoir. The 11 Series and 12 Series represent JRZ’s motorsport tier, sitting above the entire RS line.

HAND BUILT IN THE NETHERLANDS

Every JRZ RS ONE kit for the Porsche 981 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 and rear top mounts are included and engineered specifically for the 981 GT4 chassis.

FREQUENTLY ASKED QUESTIONS

What’s the difference between the RS ONE and the 11 Series?
Both are single-adjustable with rebound control and use a remote reservoir mono-tube design. The RS ONE and 11 Series differ in their internal valving architecture. Contact us for a detailed comparison based on how you use your GT4.
Is this a bolt-on install?
Yes. The RS ONE is a direct bolt-in replacement for the factory suspension on the 981 Cayman GT4. The remote reservoirs require mounting, but no cutting or fabrication is needed.
Do I need springs?
Springs are included with every kit. You choose your spring package at checkout — Street, Street/Track Hybrid, Track, or Custom rates. If you’re unsure which rates suit your use case, contact us and we’ll recommend the right setup.
Can I rebuild or revalve these later?
Yes. Every JRZ damper is fully rebuildable and revalveable. Meisterschaft Motorsport handles all service in-house — whether you need a routine rebuild after a season of track use or want to change the valving to suit a new spring rate or tyre compound.
How long is the lead time?
Typical build time is 2–4 weeks from order, depending on JRZ’s current production schedule. Contact us for the most current lead time estimate.
