  • GT3 997-specific valving — Tuned from the factory for the 997 GT3’s weight distribution, rear-engine dynamics, and high-performance suspension geometry.
  • Premium construction — CNC-machined billet aluminum and hard-anodized components built to withstand sustained track abuse.
  • Remote reservoir design — Increased fluid capacity for consistent damping performance during extended sessions, even in high ambient temperatures.
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.

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 example, firming up rebound to reduce body roll while keeping compression soft for better kerb absorption.
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 track sessions. 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.
Does this fit both 997.1 and 997.2 GT3 models?
Yes. The 11 Series is engineered to fit both the 997.1 GT3 (2005-2009, 3.6L) and the 997.2 GT3 (2009-2012, 3.8L) using the factory mounting points. Spring rates and valving can be tailored to either variant on request.
Is the 11 Series suitable for street use?
Yes. While the 11 Series is designed with track performance as its primary focus, the wide adjustment range allows you to set up a comfortable street configuration. Many owners run a softer setting for daily driving and firm things up before track days.
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 driving style. Contact us to arrange service through JRZ.
