Why Choose JRZ 12 Series Coilovers for Your GT3 996?

  • Piggyback reservoir — Compact design with the reservoir mounted directly to the damper body — no external hose lines to route, simplifying installation.
  • GT3 996-specific valving — Tuned from the factory for the 996 GT3’s lightweight construction, rear-engine dynamics, and high-revving 3.6L flat-six.
  • Premium construction — CNC-machined billet aluminum and hard-anodized components built to withstand sustained track abuse.
  • Clean packaging — The integrated piggyback design fits within the factory wheel wells without requiring additional mounting hardware for remote reservoirs.

Frequently Asked Questions

What is a piggyback reservoir?
A piggyback reservoir is a secondary fluid chamber mounted directly to the damper body. It increases the total fluid volume for better heat management and more consistent damping performance, without requiring separate mounting points or external hose lines.
How does the 12 Series compare to the 11 Series?
Both offer double-adjustable damping with independent rebound and compression control. The 12 Series uses a piggyback reservoir for simpler packaging, while the 11 Series uses a remote reservoir for greater fluid capacity and heat dissipation during extended sessions.
Is the 12 Series suitable for street use?
Yes. The wide adjustment range allows you to set up a comfortable street configuration. The compact piggyback design also makes it particularly well-suited to street use since there are no external reservoir lines to route or protect.
What other JRZ options are available for the GT3 996?
JRZ offers a comprehensive range for the GT3 996 including the 11 Series (remote reservoir), RS ONE (single-adjustable), RS TWO (twin-tube), RS PRO (triple-adjustable piggyback), RS PRO3 (triple-adjustable remote), and PROactive (electronically controlled). Contact us for help choosing the right system.
Can the 12 Series be rebuilt or revalved?
Yes. All JRZ dampers are fully serviceable. The 12 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.
