WHY THE 12 SERIES FOR THE PORSCHE 911 GT3RS 991

JRZ 12 Series Coilovers Porsche 911 GT3RS 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 12 Series Coilovers for the Porsche GT3RS 991 (2012-2015) deliver piggyback-reservoir damping in a compact, high-performance package built for the first-generation 991 GT3RS. The 12 Series features a monotube body with an integrated piggyback reservoir, providing increased oil volume and heat capacity without the complexity of remote hose lines. Valved specifically for the GT3RS’s naturally aspirated flat-six and aggressive suspension geometry, this is a race-bred damper with 2-way adjustability. Explore the full GT3RS 991 (2012-2015) lineup including the JRZ 11 Series, JRZ RS PRO, and JRZ RS PRO3.

Why Choose JRZ 12 Series Coilovers for Your GT3RS 991?

  • Piggyback reservoir design — Increased oil volume and heat capacity in a self-contained package — no external hose lines to route
  • 2-way adjustable — Independent compression and rebound adjustment lets you fine-tune balance for any track or driving style
  • Monotube construction — Direct piston-to-oil contact eliminates cavitation and delivers precise, repeatable damping
  • GT3RS-specific valving — Tuned for the 991 GT3RS’s weight, center of gravity, and track-oriented suspension geometry
  • Compact packaging — Piggyback design fits where remote reservoirs may not, simplifying installation
  • Built to order — Each set is assembled and dyno-tested at JRZ in the Netherlands to your specifications
Not sure which series?
The 12 Series is JRZ’s flagship — a motorsport-grade triple-adjustable damper at the top of the entire range. The 11 Series offers motorsport-grade double adjustment at a lower price point. For street/track use, the RS PRO3 provides triple adjustment from the RS line.

Hand Built by JRZ in the Netherlands

Every JRZ 12 Series kit is assembled by hand at JRZ Suspension Engineering in Eindhoven. Damper bodies are CNC-machined from aerospace-grade aluminum, pistons are application-specific, and each unit is individually dyno-tested before shipping. The piggyback reservoir is integrated directly onto the damper body, giving you the thermal benefits of increased oil volume in a clean, self-contained package that simplifies installation on the GT3RS 991.

JRZ 12 Series Coilovers Fitment — Porsche GT3RS 991

This kit is designed exclusively for the 2012-2015 Porsche 911 GT3RS 991 platform. JRZ engineers each application from the ground up — spring rates, valving, and reservoir sizing are calibrated for the GT3RS’s specific weight distribution, suspension geometry, and performance envelope. The result is a bolt-on system that integrates seamlessly with the GT3RS 991 chassis.

Frequently Asked Questions

What is the difference between the 12 Series and the 11 Series?
The main difference is reservoir design. The 11 Series uses a remote reservoir connected by hose lines, while the 12 Series uses a piggyback reservoir mounted directly on the damper body. Both are monotube, 2-way adjustable dampers — the 12 Series trades some oil volume for simpler installation and packaging.
Is the piggyback reservoir as effective as a remote reservoir?
For most track use, yes. The piggyback provides meaningful additional oil volume and heat capacity. Remote reservoirs offer slightly more cooling for sustained endurance-level sessions, but the 12 Series handles hard track days with consistent performance and simpler packaging.
How long does a JRZ 12 Series build take?
Each 12 Series kit is built to order at JRZ in the Netherlands. Typical lead time is 4-6 weeks depending on current production schedules. Contact us for the most current estimate.
Can I have the 12 Series revalved for different spring rates?
Yes. JRZ dampers are fully rebuildable and revalveable. If you change spring rates or modify the car’s weight, JRZ can re-dyno and revalve the dampers to match the new setup.
Will the piggyback reservoir fit in the GT3RS wheel wells?
Yes. JRZ designs the 12 Series specifically for each vehicle application. The piggyback reservoir is sized and positioned to clear the GT3RS 991’s suspension components, wheel wells, and brake hardware without modifications.
