How does the elec-TRON system change the experience on track compared to a manually adjusted ClubSport?

With a manual setup you pick a damping position before you go out and live with it for the session. The elec-TRON system makes independent adjustments at every corner 200 times per second based on what the car is actually doing; braking forces, cornering loads, acceleration inputs. The suspension is not at a fixed rate, it is continuously working out the correct valve position for the conditions at that moment.

Does the elec-TRON system work with the ClubSport's stiffer spring rates?

Yes. The DCU is configured specifically for the Type 131 Emira V6 in ClubSport specification, with spring rates of 600 lbs/inch front and 850 lbs/inch rear factored into the system's calibration. The active damping works within that setup, not around it.

What damping maps are available and how do they work?

The DCU gives access to six pre-installed maps via a 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 damping adjustments automatically. The driver sets the overall character and the DCU handles the rest.

Description

Nitron elec-TRON R1 ClubSport Coilover Kit for 131 Lotus Emira (with V6)

The Nitron elec-TRON R1 ClubSport Coilover Kit for the Type 131 Lotus Emira V6 is built for drivers who run the car hard on track and want active damping control handling the setup work in real time. The foundation is the same as the standard R1 ClubSport; four hand-built, inverted dampers with stiffer springs, firmer valving, and a lower ride height engineered specifically around the Emira V6’s geometry, weight distribution, and suspension travel. The elec-TRON system adds a proprietary proportional solenoid valve to each shock, with the included DCU monitoring g-load, vehicle speed, road conditions, and driver inputs simultaneously and making independent damping adjustments at every corner every 5 milliseconds. There is no manual adjuster to turn between sessions; the system reads what the car is doing and responds before the chassis has a chance to fall behind. Every unit is hand-built to order using titanium and hard-anodised components, fully serviceable, and upgradeable to R3 or Race Pro specifications.

elec-TRON

Nitron’s elec-TRON system starts with a proprietary proportional solenoid valve fitted to each individual shock on the Type 131 Emira V6, giving the included DCU precise, independent damping control at every corner. The system monitors g-load, vehicle speed, road conditions, and driver inputs simultaneously, making damping adjustments every 5 milliseconds. For reference, a human eye blink takes somewhere between 100 and 150 milliseconds. That processing speed means 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 included with the elec-TRON R1 ClubSport kit for the Type 131 Emira V6. It is 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 track 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.

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 Type 131 Lotus Emira V6 shape the design from the start, not as corrections added later. That’s what separates a ClubSport kit engineered for this car from one that was simply made to fit 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.
