Do I need any additional parts to run this kit on a G80 M3 Competition xDrive or G82 M4 Competition xDrive?

Yes. Because these cars come with Adaptive M Suspension from the factory, fitting a non-electronic coilover kit without addressing that system will trigger fault codes and warning lights. The Nitron Electronic Damping Delete Kit is required alongside this kit to avoid those faults.

What is the difference between the coilover and divorced rear suspension configurations?

The coilover configuration combines the spring and damper into a single unit, which keeps packaging compact and works well for road and general track use. The divorced configuration separates the spring and damper so each can be positioned and tuned independently, which is the preferred setup for dedicated race builds where geometry and tuning flexibility take priority over simplicity.

How much lift does the Standalone FAL provide, and does it affect the suspension setup?

The Nitron Standalone Front Axle Lift raises the front axle by 25mm. It lifts in under 3 seconds using a 250W pump and returns the car to its set ride height automatically once no longer needed. It has no effect on the suspension setup or how the car behaves at normal ride height.

Can I run custom spring rates with the Nitron NTR-R3?

Yes. Nitron offers custom spring rates on request. Recommended rates are available for both Fast Road Spec and Track Day Spec configurations, but if your build requires something outside those ranges, custom options are available.

Nitron NTR-R3 Coilover Kit with Standalone FAL for G8x BMW M3 Competition xDrive / M4 Competition xDrive

The G80 M3 Competition xDrive and G82 M4 Competition xDrive carry a platform that rewards serious suspension development, and the Nitron NTR-R3 Coilover Kit with Standalone FAL is built for the drivers and engineers willing to do that work. Independent 3-way damping adjustment with separate high and low speed compression control gives the range needed to properly dial the car in across different circuits and conditions, with the xDrive weight distribution and chassis loading factored into the spring rates from the start rather than treated as an afterthought. 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. 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. On the G80 M3 Competition xDrive, the Standalone FAL kit requires hose reservoir coilovers, so those come as standard; the G82 M4 Competition xDrive has more flexibility, with the FAL compatible with either piggyback or hose mounted reservoirs for front and rear. The included Standalone FAL handles the practical challenge of running a lowered xDrive car 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. 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)

Driving a lowered G8x M3 or M4 Competition xDrive on the road brings 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.
- 250W pump
- 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

Coilover vs Divorced Rear Suspension

Two rear suspension configurations are available so the kit can be tailored to how the car is actually being used. 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. That’s the preferred approach for dedicated race builds where maximizing suspension geometry and setup flexibility matters more than packaging simplicity. Nitron offers both so the R3 works with the build rather than against it.

Specialized Bi-Axis Hose Fittings

Nitron R3 hose shocks use Nitron’s proprietary 720-degree Bi-Axis fittings throughout. It’s a proprietary design that delivers clean, precise installation without the fitment compromises that come with conventional end fittings.

Unique Technology

Every Nitron shock is built from precision components that go through a thorough design and development process well 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 on how components perform together under load. Everything is machined to tight tolerances and inspected individually by trained technicians, and 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. That engineering standard is what the brand has been built on since 1998.

Bespoke Engineering

Nitron doesn’t adapt a generic damper to fit the G8x M3 and M4 Competition xDrive; they engineer one around each model. Every application goes through a dedicated development process where components, spring rates, and damping characteristics are determined by the specific platform, not borrowed from something close enough. The geometry, weight distribution, and suspension travel 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.

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.
