  • Remote reservoir design — Increased fluid capacity for consistent damping performance during multi-hour endurance stints and high ambient temperatures.
  • Premium construction — CNC-machined billet aluminum and hard-anodized components built to withstand the sustained punishment of professional racing.
  • Proven in competition — Developed from JRZ’s professional Cup car programs and trusted by teams competing in Porsche one-make series worldwide.

Frequently Asked Questions

What does double-adjustable mean?
Double-adjustable means you can independently control both rebound (the damper’s extension speed) and compression (the damper’s compression speed). This lets you tune body control and wheel compliance separately for optimal mechanical grip and driver confidence.
How does the 11 Series compare to the 12 Series?
The 11 Series uses a remote reservoir design with external hose lines, providing increased fluid capacity and better heat dissipation during extended race stints. The 12 Series uses a piggyback reservoir mounted directly to the damper body. Both offer double-adjustable damping — the choice comes down to packaging and cooling requirements.
Is this the same as the road-car GT3 997 kit?
No. The GT3 Cup 997 kit is specifically engineered for the Cup car’s racing-specification suspension geometry, mounting points, and dynamic requirements. Cup cars have different weight, ride height ranges, and tire characteristics compared to road-going GT3s.
What spring rates are available?
JRZ offers a range of spring rate options to suit different series regulations, tire compounds, and driving preferences. Contact us for recommendations based on your specific racing application and series rules.
Can the 11 Series be rebuilt or revalved?
Yes. All JRZ dampers are fully serviceable. The 11 Series can be rebuilt, revalved, and re-tuned to suit changes in your setup, tire compound, or series regulations. Contact us to arrange service through JRZ.
