JRZ PROactive electronically controlled damper for the Porsche GT3RS 991 (2012-2019). Features the patent-pending Multi-Function Control valve with 1000Hz real-time adaptive damping via 3-axis acceleration and gyro sensors. Adjustable wirelessly through a smartphone app ā€” seamlessly transitions from daily comfort to aggressive track performance without manual changes. Built to order through Meisterschaft Motorsport Engineering, the official U.S. importer of JRZ Suspension. Every set includes expert setup consultation for your Porsche.

The JRZ PROactive Coilovers for the Porsche GT3RS 991 (2012-2019) bring electronically controlled damping to the most track-focused 911 platform. The PROactive system features a multi-function control unit (MFC) that enables real-time damping adjustment, giving you the ability to switch between preset maps or make live changes from the cockpit. Purpose-built for the GT3RS’s naturally aspirated flat-six and its aggressive suspension geometry, it bridges the gap between race-car precision and intelligent adaptability. Explore the full GT3RS 991 lineup including the JRZ 11 Series, JRZ 12 Series, JRZ RS PRO, and JRZ RS PRO3.

Why Choose JRZ PROactive Coilovers for Your GT3RS 991?

  • Electronically controlled damping ā€” Multi-Function Control (MFC) valve with 1000Hz Valve Control Unit for real-time adjustment
  • Cockpit-adjustable ā€” Switch between preset maps or make live changes via Bluetooth app (Android and Apple)
  • CAN Bus compatible ā€” Can operate stand-alone or connected to the GT3RS’s vehicle network
  • 3-axis sensing ā€” Accelerometer and gyroscope sensors continuously adapt damping for cornering, braking, and acceleration
  • Built for the GT3RS 991 ā€” Valved specifically for the platform’s weight, center of gravity, and suspension geometry
  • Race-proven engineering ā€” The same technology used in professional motorsport, adapted for the GT3RS
Not sure which series?
The PROactive uses electronically controlled damping to deliver a wider adjustment range than any mechanical damper. For hands-on mechanical tuning, the RS PRO3 (triple-adjustable) or 12 Series (motorsport triple-adjustable) are excellent alternatives.

Hand Built by JRZ in the Netherlands

Every JRZ PROactive kit is assembled by hand at JRZ Suspension Engineering in Eindhoven. Damper bodies are CNC-machined from aerospace-grade aluminum, and each unit is individually dyno-tested before leaving the factory. The PROactive’s electronic control unit is calibrated for the GT3RS 991’s specific weight and dynamic characteristics, ensuring the system delivers precise damping response from the moment it’s installed.

JRZ PROactive Coilovers Fitment ā€” Porsche GT3RS 991

This kit is designed exclusively for the 2012-2019 Porsche 911 GT3RS 991 platform. JRZ engineers each application from the ground up ā€” spring rates, valving profiles, and electronic control maps are all 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

How does the PROactive system adjust damping in real time?
The PROactive uses a 1000Hz Valve Control Unit paired with 3-axis acceleration and gyroscope sensors. The system reads cornering loads, braking forces, and acceleration events continuously ā€” adjusting damping force within milliseconds. You can also override with preset maps or live adjustments through the Bluetooth app.
Can I run the PROactive without connecting to the GT3RS CAN Bus?
Yes. The PROactive can operate fully stand-alone using its own sensor suite. Connecting to CAN Bus adds vehicle data inputs but is not required for full functionality.
How long does a PROactive build take?
Each PROactive 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.
Is the PROactive serviceable?
Yes. Like all JRZ dampers, the PROactive is fully rebuildable. The electronic components can be recalibrated and the damper internals serviced by JRZ or authorized service centers.
What makes this different from adjustable coilovers with manual knobs?
Manual adjustment knobs set a fixed damping curve that stays constant until you physically turn them. The PROactive adjusts damping force 1000 times per second based on real-time vehicle dynamics data ā€” it responds to what the car is doing right now, not what you predicted it would do before the session.
