How does the manual compression adjustment on the R3 work alongside the electronic damping?

The two systems operate on separate circuits. The manual compression adjustment sets a base level of compression stiffness at each end of the car, which stays fixed until you change it. The solenoid valve and PASM system then work within that baseline, making real-time damping adjustments as normal. Adjusting the manual circuit for track use doesn't disable or override the electronic control.

Does the Standalone FAL affect suspension performance when it's not in use?

No. The Nitron Standalone Front Axle Lift operates independently of the damper setup. It does not affect spring rates, valving, or ride height when the axle is in its lowered position. Once the front axle comes back down, the car behaves exactly as it would without the FAL fitted.

Is this kit hand built to order, and can it be serviced?

Yes on both. Every Nitron elec-TRON R3 kit is custom built and custom sprung to order. Each shock is fully serviceable and can be revalved or rebuilt by Nitron. Custom spring rates are also available; contact us directly to discuss options before ordering.

Nitron elec-TRON R3 Coilover Kit with Standalone FAL for 997 Porsche 911 Carrera / Carrera GTS / Carrera S

The Nitron elec-TRON R3 Coilover Kit with Standalone FAL for the 997 Porsche 911 Carrera, Carrera GTS, and Carrera S is purpose-built for 997 owners who want the control depth of an R3 system without giving up their PASM integration or the practicality of daily driving a lowered car. The 997’s platform responds well to this kind of setup; the rear-engine weight distribution and the chassis’ inherent balance make spring rate and damping precision matter more here than on most platforms, and the R3’s layered adjustment structure is built to exploit that. Each shock carries Nitron’s proportional solenoid valve alongside an isolated high and low speed manual compression circuit, so the electronic side handles real-time damping response through PASM while the manual compression circuit gives a fixed base setting for track work or road use without the two systems fighting each other. The kit plugs into the factory PASM wiring and works with whatever driving mode the car is in. Hose-mounted reservoirs front and rear sit outside the shock body, keeping heat out of the damper oil and giving straightforward access to the adjustment controls without pulling the shocks. The Standalone FAL addresses the practical side of running a lowered 997 on public roads, lifting the front axle 25mm at the shock to clear driveways, speed bumps, and parking obstacles; once the axle drops back down the car behaves exactly as it would without the system in the circuit. Every kit is custom built to order, custom sprung, and fully serviceable.

elec-TRON

Nitron’s elec-TRON system is built around a proprietary proportional solenoid valve fitted to each shock individually on the 997 Porsche 911 Carrera, Carrera GTS, and Carrera S, giving the PASM system precise, independent damping control at every corner of the car. G-load, vehicle speed, road conditions, and driver inputs are all monitored simultaneously, with damping adjustments made every 5 milliseconds. A human eye blink takes somewhere between 100 and 150 milliseconds; the elec-TRON system is working at a fraction of that. The suspension is responding to the road and the driver in real time, not reacting after the fact.

Integration with OEM Electronic Systems

The Nitron elec-TRON R3 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.

Specialized Bi-Axis Hose Fittings

Nitron R3 hose shocks use Nitron’s own 720-degree Bi-Axis fittings exclusively; a proprietary design that makes for clean, precise installation without the compromises that come with conventional end fittings.

Unique Technology

Nitron starts every shock with precision components that go through a thorough design and development process long before final assembly. The modular construction gives engineers the flexibility to approach each application on its own terms, without compromising part quality or how components perform together under real load. Everything is machined to tight tolerances and inspected individually by trained technicians; that standard of quality control runs through every stage of production, not just the end of it. New materials, finishes, and processes go through extensive validation before they’re adopted, with proprietary Nitron technologies built in throughout to produce shocks that consistently hold up against the competition on road and track. That’s the engineering foundation the brand has been built on since 1998.
- 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 adapt a generic damper to fit the 997 Porsche 911 Carrera, Carrera GTS, or Carrera S; they engineer one around each variant. Every application goes through a dedicated development process where components, spring rates, and damping characteristics are shaped by the specific platform, not carried over from something similar enough to work. The geometry, weight distribution, and suspension travel of each model are part of the design from day one, not corrections introduced later. That’s the difference between suspension that works with a car and suspension that was purpose-built for it.

Frequently Asked Questions

What is the difference between the elec-TRON R1 and the elec-TRON R3? The elec-TRON R1 is a purely electronic system; all damping control is handled by the solenoid valve through the OEM controller with no manual compression adjustment. The elec-TRON R3 adds an isolated high and low speed manual compression circuit alongside the solenoid valve, giving drivers a fixed base compression setting that can be tuned independently for road or track use without interfering with the electronic damping side.
How does the manual compression adjustment on the R3 work alongside the electronic damping? The two systems operate on separate circuits. The manual compression adjustment sets a base level of compression stiffness at each end of the car, which stays fixed until you change it.

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.

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.
