What do the firmer springs on the Nitron Europa S NTR-R1 ClubSport change on track?

The ClubSport springs on the Nitron Europa S NTR-R1 cut pitch under braking and roll through long corners. The platform stays more stable, turn-in is sharper, and the tires stay loaded more evenly as the car approaches its limit.

Can the Nitron Europa S NTR-R1 ClubSport still be driven on the street?

Yes. The Nitron Europa S NTR-R1 ClubSport rides firmer than the FastRoad kit, but the low-friction dampers still absorb small bumps well. Softening the adjuster makes the car comfortable enough for the drive to and from the circuit.

Where should I start with the adjuster on the Nitron Europa S NTR-R1?

Start in the middle of the range on the Nitron Europa S NTR-R1, then adjust a few clicks at a time. Go firmer for smooth, high-speed circuits. Go softer for bumpy tracks, wet sessions or road driving. Note the click counts that work at each venue so you can return to them.

Does the Nitron Europa S NTR-R1 allow ride height adjustment?

Yes. Ride height on the Nitron Europa S NTR-R1 can be set at each corner, which lets you dial in stance and corner weights after installation.

How does the Nitron Europa S NTR-R1 hold up through a full track day?

The Nitron Europa S NTR-R1 is built to resist fade, so damping stays consistent as the oil heats up over back-to-back sessions. Lap times and handling balance won't drift as the day goes on.

What comes in the Nitron Europa S NTR-R1 ClubSport kit?

The Nitron Europa S NTR-R1 ClubSport kit includes four dampers with fitted springs, bearing spacers and mounting brackets for your car's drive side.

Description

Nitron NTR-R1 ClubSport Coilover Kit for 121 Lotus Europa S

Lotus pitched the Europa S as a grand tourer, but the car underneath is mostly Elise. It has the same bonded aluminum construction, the same wishbones, and a wheelbase stretched just enough to make it calm at speed. That combination makes it a better track car than its reputation suggests, as long as the suspension can keep up. The Nitron Europa S NTR-R1 ClubSport kit is the version for owners who go to the circuit often. It uses the same hand-built, race-derived dampers as the FastRoad kit, paired with firmer springs. Those springs hold the chassis flatter under hard braking, keep roll in check through long, loaded corners, and keep the tire contact patch steady when the car is near its limit. The Nitron Europa S NTR-R1 ClubSport still has a single adjuster at each corner that sets bump and rebound together. You can firm it up for a smooth, fast circuit or back it off for a bumpy track or the drive home, without working through a spreadsheet of settings.

Unique Technology

Nitron builds the NTR-R1 from its competition program, and the Nitron Europa S NTR-R1 shares much of its internal hardware with the NTR-R3, which runs in international racing. The nitrogen charge sits inside each damper body. With no external canister, the dampers stay compact and there are no hoses to clip or protect around the Europa’s suspension. Internal friction is kept extremely low, so the damper starts working as soon as the wheel moves. On track, that means the car is controlled the moment it lands over a curb or crest, and it doesn’t take a couple of oscillations to settle. On the Nitron Europa S NTR-R1 ClubSport, the quick response helps the firmer springs too. Small, sharp inputs get absorbed before they unsettle the car, so the stiffer setup still finds grip on patched or uneven tarmac. Heat-induced fade is well controlled as well, and lap twenty feels like lap two.
- 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 build any Nitron Europa S NTR-R1 ClubSport kit until it’s ordered. Each one is assembled by hand, with valving developed to work with the firmer spring package and with how the car will actually be used, from regular track days to timed events. Titanium and hard-anodized parts take weight out of each corner and resist corrosion, which matters on a car that spends its weekends getting rained on in paddocks and its weekdays parked outside. Every damper in the Nitron Europa S NTR-R1 ClubSport kit is fully serviceable, so a car that racks up a lot of track time can have its dampers refreshed and returned to as-built performance. If you’re running sticky tires, adding aero, or aren’t sure whether ClubSport or FastRoad suits your plans, contact us directly before ordering.

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.
