Does the elec-TRON system replace manual damping adjustment entirely?

Yes. The solenoid valve on each shock handles damping continuously based on real-time inputs from the DCU. There is no adjuster knob to turn. You select a damping map via the rotary switch and the system manages everything from there, making adjustments 200 times per second based on what the car is actually doing.

Does the FAL affect the suspension tune or the elec-TRON system in any way?

No. The lift operates independently of both the damper setup and the DCU. It does not affect 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.

Nitron elec-TRON R1 Coilover Kit w/ Standalone FAL for 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo S

The Nitron elec-TRON R1 coilover kit for the 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo S, supplied here with Nitron’s Standalone Front Axle Lift system, brings electronic damping control through Nitron’s proportional solenoid valve with all damping managed by the Nitron DCU, which is sold separately. Droplinks are included so the installation is complete without sourcing additional hardware. 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 these AWD and turbocharged 996 variants, where the platform’s performance foundation is already strong and the suspension just needs to keep up with precision rather than complexity. The included FAL addresses the practical challenge of running a lowered 996 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 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo S runs on Nitron’s Standalone Electronic Damping configuration. Each shock carries its own proprietary proportional solenoid valve, giving the DCU 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.

Standalone Electronic Damping System

The Nitron DCU is required for the elec-TRON R1 with Standalone FAL kit on the 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo S and is sold separately. It’s the brain behind the elec-TRON system, transforming a conventional passive damper setup into a precision semiactive platform. Working in conjunction with Nitron’s elec-TRON valve, the DCU continuously processes data from the car every 5 milliseconds; assessing vehicle attitude, braking forces, cornering loads, and acceleration inputs to determine the correct valve position and damping level at any given moment. The result is a suspension system that isn’t set to a fixed damping rate but is constantly optimizing grip and performance in real time based on what the car is actually doing. The DCU is fitted with an adjustable control knob giving the driver access to a range of pre-installed damping maps; Rain, Tour, Sport, and Race; each tuned for a specific driving context. Damping continues to be adjusted continuously within whichever map is selected, so the driver sets the overall character and the system handles the rest.

The Nitron Front Axle Lift (FAL)

Running a lowered 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, or Turbo 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.

- 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.

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 996 Porsche 911 Carrera 4, Carrera 4S, Turbo, and Turbo 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.

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.

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.
