How do firmer springs help the Elise 111R in fast corners?

At high corner speeds on sticky tires, road-biased springs let the Elise 111R lean further and move around over crests and bumps. The Nitron 111R NTR-R1 ClubSport uses firmer spring rates than the FastRoad kit, so the body holds a steadier attitude and ride height through fast sweepers. The car stays composed when stability matters most.

Who should choose the Nitron Elise 111R NTR-R1 ClubSport?

The Nitron Elise 111R NTR-R1 ClubSport suits 111R and Elise R owners who track their car regularly or run sticky tires but still drive it on the road. It uses the same NTR-R1 damper as the FastRoad with slightly stiffer springs. Owners building a full race car may be better served by the Nitron RacePro 3.

Are mounting brackets included with the Nitron 111R NTR-R1 ClubSport?

Yes. Mounting brackets are included with every Nitron 111R NTR-R1 ClubSport kit and are supplied to suit your car’s drive side. Select LHD or RHD when ordering, and the kit arrives with the correct brackets to fit the factory double wishbone suspension without sourcing extra hardware.

Can the Nitron NTR-R1 ClubSport be softened for the road?

Yes. Each Nitron NTR-R1 damper has a single adjuster that sets bump and rebound together, so a few clicks per corner take the edge off for the drive to the circuit. You can firm the Elise 111R back up in the paddock without balancing separate damping circuits, then soften it again for the trip home.

Can the Nitron Elise 111R NTR-R1 ClubSport be serviced and revalved?

Yes. Every Nitron Elise 111R NTR-R1 ClubSport damper is fully serviceable, so it can be rebuilt after a season of track days, revalved or fitted with different springs. If your 111R moves toward competition or back toward the road, the setup can be updated to match.

Nitron NTR-R1 ClubSport Coilover Kit for S2 Lotus Elise 111R / R

The Toyota-powered Elise 111R carries more speed into a corner than most S2s, and you notice that most in fast, loaded sweepers. On road-biased springs, the body leans further, the car takes longer to settle, and a crest or bump mid-corner can leave it moving around just as you need it steady. The Nitron 111R NTR-R1 ClubSport coilover kit firms things up for that kind of driving. Its spring rates are a step stiffer than the FastRoad kit’s, so the Elise holds a steadier ride height and body attitude through high-speed corners and stays composed over crests at track pace. It’s still usable on the road, but the ClubSport is aimed at owners whose 111R sees regular circuit days on sticky tires. One adjuster per corner sets bump and rebound together, so you can soften it for the drive to the track and firm it up in the paddock. The kit fits both the Elise 111R and the later Elise R. Mounting brackets for your car’s drive side are included, so the Nitron Elise 111R NTR-R1 ClubSport bolts straight into the factory double wishbone suspension.

Unique Technology

Nitron’s NTR-R1 uses hardware developed in its race program, much of it shared with the NTR-R3 that competes in international motorsport. There’s no remote canister, so each damper stays compact and installs without any hoses to route. Firmer springs put more load through the dampers, especially at high speed. The low-friction internals of the Nitron NTR-R1 respond quickly to those loads, so the tires stay planted over curbs and fast, bumpy corners instead of skating across the surface. Fade resistance matters too, since a quick 111R on sticky tires can lap hard for a long time. The Nitron 111R NTR-R1 ClubSport holds its damping from the first lap of a session to the last.
- 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

Every Nitron 111R NTR-R1 ClubSport kit is assembled by hand to order, with springs and valving matched to the Elise 111R and a track-leaning brief. That suits owners who drive to the circuit on track tires, run a full day of sessions and drive home, as well as cars that have become dedicated track-day machines with brake and cooling upgrades. Hard-anodized and titanium-finish components keep weight down on a car built around low mass, and they resist corrosion through wet track days and winter storage. These dampers are built to be maintained, not replaced. Each Nitron NTR-R1 unit can be fully serviced and revalved, and the springs can be changed, so the setup can follow the car toward competition or back toward the road.

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.
