WHY THE 11 SERIES FOR THE PORSCHE 911 GT3 991

JRZ 11 Series Coilovers Porsche 911 GT3 991 — 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 11 Series Coilovers bring motorsport-derived twin-adjustable damping to the Porsche 911 GT3 991 (2012–2019). Designed and hand-assembled in the Netherlands by JRZ Suspension Engineering, the 11 Series provides independent compression and rebound control — giving drivers precise authority over body control, weight transfer, and mechanical grip without the complexity of a triple-adjustable platform. Built for serious enthusiasts who want professional-grade performance with a straightforward tuning interface. Explore the full 911 GT3 991 coilover lineup: 12 Series · RS PRO · RS PRO3 · RS ONE.

Why the JRZ 11 Series for Your 911 GT3?

  • Twin-adjustable damping — independent compression and rebound adjustment lets you dial in the perfect balance between grip and compliance for any surface or driving style.
  • Monotube construction — consistent, fade-free damping under sustained hard driving, from spirited back roads to full track-day sessions in the 991 GT3’s naturally aspirated flat-six.
  • Height-adjustable spring perches — set your ride height without compromising suspension travel, maintaining the geometry Porsche’s engineers designed around.
  • Revalveable and rebuildable — JRZ’s open-service design means your dampers evolve with your setup; swap valve shims to match new tires, aero, or alignment changes.
Not sure which series?
The 11 Series is JRZ’s motorsport-grade double-adjustable damper, sitting above the entire RS line in the JRZ hierarchy. For triple-adjustable motorsport control, step up to the 12 Series. For street/track alternatives, the RS PRO and RS PRO3 offer excellent performance from the RS line.

Hand-Built in the Netherlands

Every JRZ 11 Series damper is assembled by a single technician in Breda, Netherlands. Each unit is dyno-tested against its target force curve and serialized before it leaves the facility. This is not mass production — it is precision manufacturing backed by decades of motorsport R&D at the highest levels of professional racing.

JRZ 11 Series Coilovers — Fitment: Porsche 911 GT3 991 (2012–2019)

This kit is engineered specifically for the Porsche 911 GT3 on the 991 platform, covering both the 991.1 (3.8L) and 991.2 (4.0L) naturally aspirated flat-six variants. The 11 Series bolts into the factory mounting points with no permanent chassis modifications, and ride height is set through threaded spring perches — preserving full suspension travel at any stance.

Frequently Asked Questions

What is the difference between the 11 Series and 12 Series?
The 11 Series is twin-adjustable (compression and rebound), while the 12 Series is triple-adjustable (high-speed compression, low-speed compression, and rebound). The 12 Series offers a wider tuning window, but the 11 Series delivers outstanding performance with a simpler adjustment interface — ideal for drivers who want professional damping without the added complexity.
Can I run these on the street?
Yes. The 11 Series is fully street-friendly when set to softer damping positions. Many GT3 owners daily-drive on JRZ coilovers and simply firm up the adjusters for track days — no spring changes required.
Do I need to modify my chassis to install these?
No. The 11 Series bolts directly into the Porsche 911 GT3 991 factory mounting points. No cutting, drilling, or welding is required.
How often should I service JRZ dampers?
JRZ recommends a service interval based on usage — typically every 20,000–30,000 road kilometers or every 30–50 track hours. Service includes fresh oil, new seals, and a dyno re-test to confirm performance.
Does this fit both 991.1 and 991.2 GT3?
Yes. This kit covers the full 991 GT3 production run from 2012 through 2019, including both the 991.1 (3.8L) and 991.2 (4.0L) variants.
