How does the Nitron 340R NTR-R1 FastRoad differ from the ClubSport?

Both kits use the same Nitron NTR-R1 damper with combined 2-way adjustment. The Nitron 340R NTR-R1 FastRoad has softer, road-biased spring rates, which suit owners who drive the Lotus 340R mostly on the road with the odd track day. The ClubSport kit uses slightly stiffer springs for drivers who spend more time on circuit and want tighter body control.

What makes the Nitron 340R NTR-R1 FastRoad suited to road driving?

The Nitron 340R NTR-R1 FastRoad uses road-biased spring rates, so the Lotus 340R can move with crests, compressions and broken tarmac. Its low-friction Nitron NTR-R1 dampers keep the body under control and the steering feedback clear. The car stays composed at road speeds without the jittery, skipping feel of a stiff, track-focused setup.

Does the Nitron Lotus 340R NTR-R1 FastRoad need mounting brackets?

No. The Nitron Lotus 340R NTR-R1 FastRoad fits the car’s double wishbone suspension directly, with no mounting brackets required. That keeps the install simple and means nothing about the car’s original mounting points has to change, which matters on a car as rare as the 340R.

How do you adjust the Nitron NTR-R1 on a 340R?

Each Nitron NTR-R1 damper has one adjuster that changes bump and rebound together along a curve Nitron sets for the car. Turn it firmer for a track day or softer for road driving. With a single adjuster per corner, you can change the 340R’s setup in a few minutes without balancing separate damping circuits.

Can the Nitron 340R NTR-R1 FastRoad be rebuilt later?

Yes. Every Nitron 340R NTR-R1 FastRoad damper is fully serviceable, so it can be rebuilt, revalved or fitted with different springs. For a car as rare as the Lotus 340R, that means the suspension can be kept in top condition for years, or moved toward a firmer setup, rather than replaced.

Description

Nitron NTR-R1 FastRoad Coilover Kit for 111 Lotus 340R

Lotus built only 340 examples of the 340R, and the cars that survive tend to fall into two groups. Some are rarely driven and kept out of the weather. Others are driven the way Lotus intended, on narrow, uneven roads at real speed. The Nitron 340R NTR-R1 FastRoad coilover kit is for the second group. Nitron sets up the FastRoad version with softer, road-biased spring rates than the ClubSport kit, so this skeletal, open-bodied car can breathe over crests, compressions and patched surfaces instead of skittering across them. In a car with no doors, no roof and every suspension component on show, how well the dampers control the wheels is felt immediately through the seat and the steering. The Nitron NTR-R1 keeps that feedback sharp while removing the jitter. One adjuster per corner sets bump and rebound together, so a few clicks firm the car up for a track day and soften it again for the drive home. No mounting brackets are needed, and the Nitron Lotus 340R NTR-R1 FastRoad fits straight into the car’s double wishbone suspension.

Unique Technology

Nitron took the NTR-R1 from its race program, and it shares much of its internal hardware with the NTR-R3 used in international motorsport. The NTR-R1 has no remote canister, so each damper stays compact enough to sit neatly among the exposed wishbones and keep the car’s lines clean. Very low internal friction lets the damper respond the instant a wheel moves. With so little weight over each corner of a 340R, that keeps the tires following the road rather than hopping across ripples and broken edges. Nitron’s NTR-R1 also resists fade. The damping holds steady through a long drive in summer heat or a full track session, so the car feels the same at the end as it did at the start.
- 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

Each Nitron 340R NTR-R1 FastRoad kit is hand-built to order, with springs and valving chosen for this car and for a road-first brief. That suits owners who drive their 340R regularly, take on long road trips and occasional track days, and want the car to stay compliant rather than becoming a firmly sprung track toy. Hard-anodized and titanium-finish components keep weight down on a car where low mass is the whole point. They also resist corrosion on an open car that’s exposed to more weather than nearly anything else on the road. With so few 340Rs left, the parts on them need to last. Every Nitron NTR-R1 damper can be fully serviced and revalved, and the springs can be changed. The kit can be refreshed for years and moved toward a firmer setup if the car starts spending more time on track.

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.
