Does the FAL system work at speed or only at low speeds?

The FAL is designed for low-speed obstacle clearance; driveways, parking lots, and speed bumps. The auto off function is part of how the system manages appropriate use. Once the front axle returns to ride height, the suspension operates exactly as configured with no effect on handling.

Does lowering the M4 enough to need front axle lift affect the suspension geometry?

Not with this setup. The NTR-R1 is custom sprung to order around the specific ride height rather than adapted from a stock-height baseline. The FAL system operates independently of the coilover setup, returning the car to its configured ride height without touching spring rates, damping settings, or alignment.

At what point does the divorced rear configuration make more sense than the coilover setup?

When the build is moving toward dedicated circuit use and geometry optimization becomes a priority over installation simplicity. The divorced setup allows the spring and damper to be positioned and adjusted independently, which opens up setup options that a coilover configuration physically can't offer. For road use or occasional track days, the coilover setup covers everything needed without the added complexity.

Nitron elec-TRON R1 Coilover Kit with Standalone FAL for F82 BMW M4 / M4 Competition

The F82 BMW M4 and M4 Competition respond well to a properly developed suspension setup, and the Nitron elec-TRON R1 Coilover Kit with Standalone FAL brings electronic damping control through Nitron’s proportional solenoid valve, managed directly by BMW’s existing Electronic Damping Control (EDC) system. No additional controller is required; the kit integrates with EDC as it sits, so nothing is lost from the factory interface. Coilover and divorced rear suspension configurations are both available to suit different build requirements, and the kit includes droplinks so the installation is complete without sourcing additional hardware. The kit includes adjustable top mounts and race springs, covering the same broad adjustment range as the R3 without the independent compression adjustment and remote reservoirs. 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. The included Standalone FAL addresses the practical challenge of running a lowered M4 on public roads, raising the front axle by 25mm to clear driveways, speed bumps, and parking obstacles without affecting the suspension setup or how the car drives once conditions return to normal.

elec-TRON

The elec-TRON R1 with Standalone FAL for the F82 M4 and M4 Competition uses Nitron’s proportional solenoid valve fitted to each shock individually, with all damping managed directly through BMW’s existing EDC system. Each shock carries its own valve, giving EDC precise, independent damping control at every corner simultaneously. The system processes brake pressure, g-force, acceleration, steering inputs, and vehicle speed all at once, making damping adjustments in real time. The suspension is reacting to what the road and the driver are doing as it happens, not catching up after the fact.

The Nitron Front Axle Lift (FAL)

Running a lowered F82 M4 or M4 Competition 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.

Coilover vs Divorced Rear Suspension

The F82 M4 and M4 Competition elec-TRON R1 with Standalone FAL is available with two rear suspension configurations depending on how the car is being built. The coilover setup combines the spring and damper into a single unit, keeping things compact and straightforward for road and general track use. The divorced configuration separates the spring and damper, allowing each to be positioned and tuned independently; this is the preferred approach for dedicated race builds where maximizing suspension geometry and setup flexibility matters more than packaging simplicity. Nitron offers both to make sure the R1 works with the build rather than against it.

Integration with OEM Electronic Systems

The Nitron elec-TRON R1 with Standalone FAL goes in as a direct bolt-in replacement on the F82 M4 and M4 Competition, picking up the existing EDC integration without any modification needed. Factory functionality stays intact; EDC continues to operate exactly as designed, with significantly more capable hardware now doing the actual work.

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 F82 M4 and M4 Competition 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.

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.
