Why Choose JRZ 11 Series Coilovers for Your GT3 991?

  • Double-adjustable damping — Independent rebound and compression adjustment lets you fine-tune body control and wheel compliance separately for optimal balance.
  • Motorsport heritage — Developed from JRZ’s professional racing programs and trusted by GT3 competitors at every level.
  • GT3-specific valving — Tuned from the factory for the 991.1 GT3’s weight, geometry, and high-performance envelope — not a generic fit.
  • 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.

Each unit undergoes individual dyno testing and is validated against strict performance tolerances before shipping. This artisan approach ensures that every set of 11 Series coilovers delivers consistent, race-ready performance from the moment they’re installed on your GT3 991.

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.
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.
Does this fit the 991.2 GT3 as well?
This specific kit is designed for the 991.1 GT3 (2012-2015). For the 991.2 GT3 (2017-2019), please see the GT3 991 (2012-2019) fitment which covers both generations. Contact us if you need help identifying the correct kit for your car.
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.
