Will the Nitron Elise NTR-R1 FastRoad bring back the S1’s original ride quality?

Yes, and it improves on it. The Nitron Elise NTR-R1 FastRoad keeps the S1’s soft-sprung, well-damped approach with road-biased spring rates. Its low-friction Nitron NTR-R1 dampers add control that original or worn dampers can’t match. The car flows over broken roads again while the steering keeps the clarity the S1 Elise is known for.

How does the Nitron S1 Elise NTR-R1 FastRoad compare with the ClubSport and RacePro 3?

The Nitron S1 Elise NTR-R1 FastRoad and ClubSport share the same NTR-R1 damper with combined 2-way adjustment. The FastRoad uses softer, road-biased springs, while the ClubSport uses slightly stiffer springs for owners who spend more time on track. The RacePro 3 is the full-race kit, with independent 3-way adjustment for dedicated competition cars.

Does the Nitron S1 Elise NTR-R1 FastRoad need mounting brackets?

No. The Nitron S1 Elise NTR-R1 FastRoad fits the car’s factory double wishbone suspension directly, with no mounting brackets required. That keeps the install simple and leaves the original mounting points untouched, which suits owners who want to keep their S1 close to how Lotus built it.

How is the damping adjusted on the Nitron NTR-R1?

Each Nitron NTR-R1 damper has one adjuster that changes bump and rebound together along a curve Nitron sets for the car. Turning it firmer stiffens both directions, and turning it softer relaxes both. On an S1 Elise, that makes it quick to switch between a comfortable road setting and a tighter track setting.

Can the Nitron Elise NTR-R1 FastRoad be rebuilt later?

Yes. Every Nitron Elise NTR-R1 FastRoad damper is fully serviceable, so it can be rebuilt, revalved or fitted with different springs. For an S1 Elise you plan to keep for years, that means the suspension can be maintained in top condition, or moved toward a firmer setup, instead of being replaced.

Description

Nitron NTR-R1 FastRoad Coilover Kit for S1 Lotus Elise

People who drove the S1 Elise when it was new still talk about the way it rode. It flowed over bumpy roads that would unsettle far more expensive cars, with steering that told you exactly what the front tires were doing. Decades later, most S1s are on dampers that are tired or poorly matched, and much of that magic is gone. The Nitron Elise NTR-R1 FastRoad coilover kit brings it back, then improves on it. Nitron sets up the FastRoad version with softer, road-biased spring rates than the ClubSport kit. That keeps the soft-sprung, well-damped approach that defined the S1 and adds control that original-equipment dampers never had. The body stays calm over broken surfaces, the tires stay in contact and the steering keeps its clarity. One adjuster per corner sets bump and rebound together, so a few clicks change the car from a relaxed road setting to something tighter for a track day. No mounting brackets are needed, and the Nitron S1 Elise NTR-R1 FastRoad fits straight into the factory double wishbone suspension.

Unique Technology

The Nitron NTR-R1 came out of Nitron’s race program, and it shares much of its internal hardware with the NTR-R3 used in international motorsport. With no remote canister, each damper stays compact and easy to package, and the install is a simple bolt-in. The internals are very low friction, so the damper starts working the moment a wheel moves. On a car as light as the S1 Elise, that’s what keeps the ride supple over small, sharp imperfections and keeps the steering free of the jitter a sticky damper adds. The Nitron NTR-R1 also resists fade. The damping you set holds through a long summer drive 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 Elise NTR-R1 FastRoad kit is built by hand once it’s ordered, with springs and valving matched to the S1 Elise and to a road-first brief. That suits owners who use their S1 the way Lotus intended. They cover real road miles, take it on weekend drives and run the occasional track day, without wanting the firmer ride of a track-focused setup. Hard-anodized and titanium-finish components keep weight down on a car built around low mass, and they resist corrosion through wet weather and winter storage. An S1 is a car people keep for the long haul, so its parts 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’s use changes.

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.
