How does the elec-TRON R1 interact with PASM when the FAL is also fitted?

The three systems operate independently of each other. PASM manages damping through Nitron's solenoid valve hardware as it normally would, and the FAL raises and lowers the front axle on demand without any interaction with the damper setup or the PASM system. Fitting the FAL does not affect how PASM operates or how the elec-TRON hardware performs.

Does this kit work on both PASM and non-PASM equipped 997 models?

This kit is designed specifically for 997 models equipped with PASM. If your car was not optioned with PASM, the NTR-R1 with Standalone FAL is the correct kit for your application.

Does the FAL affect the suspension tune or damping setup in any way?

No. The lift operates independently of the damper setup and does not change spring rates, valving, or ride height when not in use. Once the front axle comes back down the car behaves exactly as it would without the FAL fitted.

Description

Nitron elec-TRON R1 Coilover Kit with Standalone FAL for 997 Porsche 911 Carrera / Carrera GTS / Carrera S

The Nitron elec-TRON R1 coilover kit for the 997 Porsche 911 Carrera, Carrera GTS, and Carrera S, supplied here with Nitron’s Standalone Front Axle Lift system, integrates directly with Porsche’s PASM electronic damping system, adding Nitron’s proportional solenoid valve to each shock for precise, independent damping control at every corner. No additional controller is required. The hardware traces directly back to the R3 platform, so what you’re getting is proven race-derived componentry packaged into a more accessible, straightforward setup; one that works particularly well on the 997, where the chassis already provides a strong handling foundation and the suspension just needs to keep up with precision rather than complexity. The included FAL addresses the practical challenge of running a lowered 997 on public roads, raising the front axle 25mm at the shock to clear driveways, speed bumps, and parking obstacles without affecting the suspension setup or how the car drives once conditions return to normal. Every kit is custom built, custom sprung, and fully serviceable.

elec-TRON

The elec-TRON R1 for the 997 Porsche 911 Carrera, Carrera GTS, and Carrera S integrates with Porsche’s PASM electronic damping system rather than replacing it. Each shock carries its own proprietary proportional solenoid valve, giving PASM precise, independent damping control at every corner simultaneously. The system monitors g-load, vehicle speed, road conditions, and driver inputs all at once, making damping adjustments every 5 milliseconds. For reference, a human eye blink takes somewhere between 100 and 150 milliseconds. The suspension is reacting to what the road and the driver are doing in real time, not catching up after the fact.

Integration with OEM Electronic Systems

The Nitron elec-TRON R1 with Standalone FAL installs as a direct bolt-in replacement on the 997 Porsche 911 Carrera, Carrera GTS, and Carrera S, integrating with Porsche’s PASM system without modification. PASM continues to operate as intended, retaining full factory damping system functionality, just with significantly more capable hardware doing the work underneath the car. No additional controller is required.

The Nitron Front Axle Lift (FAL)

Running a lowered 997 Porsche 911 Carrera, Carrera GTS, or Carrera S on the road comes with a familiar set of frustrations; steep driveways, speed bumps, and parking lot ramps that sit just low enough to make every approach a calculation. The Nitron Standalone Front Axle Lift system is built around that specific problem. With 25mm of lift available at the front axle, it clears the obstacles that lowered ride heights make problematic without requiring any changes to the suspension setup and without affecting how the car performs once you’re back on the road or circuit. It’s a practical addition to a performance suspension package, not a compromise of one.

- 25mm lift height
- Typical lift time under 3-seconds
- Audible in-cabin warning system
- Switch with built-in warning light
- Auto off function
- Protects your car from damage caused by steep driveways and speed bumps
- Compatible with a wide range of suspension setups

Unique Technology

Nitron builds every shock around precision components that go through a thorough design and development process long before final assembly. The modular construction gives engineers the room to develop each application properly on its own terms, without cutting corners on part quality or how components work together under load. Everything is machined to tight tolerances and inspected individually by trained technicians; quality control isn’t a final step here, it runs through the entire process. New materials, finishes, and processes are validated extensively before they’re brought into production, with proprietary Nitron technologies woven throughout to produce shocks that hold up against the competition on both road and track. That level of engineering discipline is what the brand has been built on.
- Basic Damper Design:
  1. End Eye / Top Mount
  2. Damper Piston & Shim Stack
  3. Shaft / Rod
  4. Floating / Separator Piston
  5. Suspension Oil
  6. Compressed Nitrogen Gas

Bespoke Engineering

Nitron doesn’t start with a generic damper and work backward from there. Every application is developed from the ground up, with components, spring rates, and damping characteristics determined by the specific platform rather than borrowed from something adjacent. The geometry, weight distribution, and suspension travel of the 997 Porsche 911 Carrera, Carrera GTS, and Carrera S shape the design from the start, not as corrections added later. That’s what separates a kit engineered for these cars from one that was simply made to fit them.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
