How does the elec-TRON RoadSport differ from the elec-TRON R1 on the F87 M2?

Both use Nitron's proportional solenoid valve, but they're built for different briefs. The elec-TRON RoadSport retains OEM top mounts and is developed around daily road use to preserve ride comfort and noise isolation. The elec-TRON R1 uses adjustable top mounts and spring rates developed for track use, making it the better choice when circuit performance takes priority over road refinement.

Why does the elec-TRON RoadSport retain the OEM top mounts?

The factory top mounts are part of what makes the M2 and M2 Competition comfortable and refined to drive daily. Replacing them with adjustable motorsport units introduces more noise, vibration, and harshness into the cabin. For an owner who drives the car regularly on the road, retaining the OEM mounts is the right trade-off; the handling improvement comes from the damper itself.

Nitron elec-TRON RoadSport Coilover Kit for F87 BMW M2 / M2 Competition

The F87 BMW M2 and M2 Competition make a strong case for being driven every day, and the Nitron elec-TRON RoadSport coilover kit is developed around exactly that kind of use. Where most performance suspension upgrades push you toward a compromise between daily comfort and improved capability, the elec-TRON RoadSport doesn’t force that choice. It uses Nitron’s proportional solenoid valve to manage suspension response in real time without any manual adjustment required from the driver. The kit is designed around the factory OEM top mounts, keeping noise, vibration, and harshness in check so the car stays composed and comfortable on the road while delivering noticeably sharper handling over the stock setup. The hardware carries over core technology from the R1 kit, so there’s genuine engineering substance behind the comfort-focused brief.

elec-TRON

Each shock in the elec-TRON RoadSport carries its own proprietary proportional solenoid valve, giving the system precise, independent damping control at every corner simultaneously. The system reads g-load, vehicle speed, road conditions, and driver inputs all at once, making damping corrections every six milliseconds. To put that in context, a blink of the human eye takes between 100 and 150 milliseconds. The suspension isn’t approximating what the road is doing; it’s keeping up with it in real time.

Unique Technology

Nitron builds every shock from precision components that go through a rigorous design and development process well before the unit reaches final assembly. The modular construction gives engineers the flexibility to work through each application properly without cutting corners on how parts are made or how they perform together under real load. Everything is machined to tight tolerances and checked individually by trained technicians; that level of quality control isn’t concentrated at the end of the process, it runs through all of it. New materials, finishes, and processes are put through extensive validation before they’re brought into production, with proprietary Nitron technologies integrated throughout to produce shocks that hold their own against the competition on road and track alike. That discipline in engineering is what the brand has stood on since day one.
- 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 reverse engineer a fit for the F87 M2 and M2 Competition. Every application is developed from scratch, with components, spring rates, and damping characteristics built around the specific platform rather than adapted from something in the same ballpark. The F87’s geometry, weight distribution, and suspension travel are factored into the design from the beginning, not addressed as afterthoughts. That’s the gap between a kit that happens to fit the M2 and one that was actually engineered for it.

About Nitron Suspension

Nitron Suspension has been at the forefront of precision suspension engineering since 1998, founded by Guy Evans with the goal of building high-performance shocks for enthusiasts and professionals alike. Over 200 dealers now carry Nitron products across Europe, Asia, the US, Australasia, and Africa. In 2008, the company moved into a dedicated facility in the UK’s Motorsport Valley, adding dynamometers, 5-axis CNC machines, and 3D CAD capabilities to support both growing demand and continued product development. A second expansion came in 2023 with a new office in Murrieta, California. The team behind every Nitron product draws from deep backgrounds in machining, materials technology, hydraulics, bike engineering, and F1 racing, with many engineers bringing firsthand experience as competitive drivers and riders. That depth of knowledge across both the technical and competitive sides of motorsport shapes every product Nitron develops.

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.
