Does the Standalone FAL affect the suspension setup or how the car drives 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.

Does the Nitron NTR-R3 require the Electronic Damping Delete Kit on a PASM-equipped 997 Carrera 4, Carrera 4 GTS, Carrera 4S, Turbo, or Turbo S?

Yes, if your car was factory-equipped with PASM. Fitting a passive coilover kit to a PASM-equipped 997 without addressing the factory electronic damping system will trigger fault codes and warning lights. The Nitron Electronic Damping Delete Kit prevents those faults cleanly and is required alongside the NTR-R3 on any PASM-equipped car.

Can the Nitron NTR-R3 be revalved or adjusted after purchase, and are custom spring rates available?

Yes on both. Every Nitron NTR-R3 kit is fully serviceable and can be revalved or rebuilt by Nitron. Custom spring rates are available at the time of order; contact us directly before ordering if your intended use or setup calls for something outside the standard specification.

Nitron NTR-R3 Coilover Kit w/ Standalone FAL for 997 Porsche 911 Carrera 4, Carrera 4 GTS, Carrera 4S, Turbo, and Turbo S

The 997 Porsche 911 Carrera 4, Carrera 4 GTS, Carrera 4S, Turbo, and Turbo S are capable platforms from the factory, but the suspension still leaves real capability on the table when the driving gets serious. The Nitron NTR-R3 coilover kit, supplied here with Nitron’s Standalone Front Axle Lift system, is built for that level of development work; independent 3-way damping adjustment with separate high and low speed compression control gives drivers and engineers the range needed to properly dial the car in across different circuits and conditions. A large diameter piston and ultra-strong piston rod sit at the core of the design, providing the damping control and feedback that serious setups depend on. Both front and rear units use hose mounted reservoirs; the fronts feature quick-release dry-breaks as standard, with the option to add them to the rears as well, keeping high and low speed compression adjustment accessible at both ends. 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. The R3 is a proven race winner with lap records across a wide range of international motorsport formulas, and every kit is custom built, custom sprung, and fully serviceable.

The Nitron Front Axle Lift (FAL)

Running a lowered 997 Porsche 911 Carrera 4, Carrera 4 GTS, 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.

- 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

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 builds every shock from 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 cutting corners on part quality or how components perform together under load. Everything is machined to tight tolerances and inspected individually by trained technicians; that quality control runs through every stage of production rather than being concentrated at the end. New materials, finishes, and processes are validated extensively before adoption, with proprietary Nitron technologies integrated throughout to produce shocks that consistently hold up against the competition on road and track. That engineering standard is what 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 4, Carrera 4 GTS, Carrera 4S, Turbo, and Turbo S; they engineer one around each platform. Every application goes through a dedicated development process where components, spring rates, and damping characteristics are determined by the specific variant, not borrowed from something close enough. The geometry, weight distribution, and suspension travel of each model are part of the design from the beginning, not corrections introduced later. That’s the difference between suspension that works with a car and suspension that was developed for it.

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.
