How does the elec-TRON system work alongside the R3's manual compression adjusters?

The DCU controls overall damping through the solenoid valve at 200Hz, but the high and low speed compression adjusters on the piggyback reservoirs remain fully independent and accessible. You still have manual control over the mechanical side of the setup; the elec-TRON layer works alongside it, not instead of it. Between the two you have control over both the active and mechanical sides of the damping simultaneously.

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

No. The lift system 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.

What damping maps does the DCU offer?

Six pre-installed maps are accessible via the rotary control switch; three passive and three adaptive. Rain, Tour, Sport, and Race cover the core driving contexts. Within whichever map is selected, the system continues making continuous adjustments automatically at 200Hz. The driver sets the overall character and the DCU handles the rest.

Nitron elec-TRON R3 FastRoad Coilover Kit w/ Standalone FAL for 131 Lotus Emira (with V6)

The Nitron elec-TRON R3 FastRoad Coilover Kit with Standalone Front Axle Lift for the Type 131 Lotus Emira V6 combines electronic damping control through Nitron’s proportional solenoid valve with independent manual compression adjustment, giving drivers and engineers control over both the active and mechanical sides of the damping setup simultaneously. The included 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. Piggyback reservoirs front and rear allow for straightforward independent adjustment of high and low speed compression, while the DCU handles overall damping in real time. The Standalone FAL addresses the practical challenge of running the Emira V6 at those ride heights on public roads, raising the front axle 25mm in under 3 seconds 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

Nitron’s elec-TRON system is built around a proprietary proportional solenoid valve fitted to each shock individually on the Type 131 Emira V6, giving the included DCU 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.

Standalone Electronic Damping System

The Nitron DCU is included with the elec-TRON R3 FastRoad with Standalone FAL for the Type 131 Emira V6. 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 Type 131 Lotus Emira V6 at R3 ride heights 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 lower 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.

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.

Bespoke Engineering

Nitron doesn’t adapt a generic damper to fit the Type 131 Lotus Emira V6; they engineer one around it. 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 the Emira V6 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.

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.
