Who should choose the Nitron S3 Exige S NTR-R1 ClubSport over the FastRoad kit?

The Nitron S3 Exige S NTR-R1 ClubSport suits S3 Exige S owners who track the car regularly, run sticky Cup-style tires or want tighter body control. Its spring rates are a bit stiffer than the FastRoad kit’s. Both kits use the same Nitron NTR-R1 damper with combined 2-way adjustment, so the difference comes down to the springs.

Is the Nitron S3 Exige S NTR-R1 ClubSport too stiff for road driving?

No. The Nitron S3 Exige S NTR-R1 ClubSport is firmer than the FastRoad kit, but it is still usable on the road. The low-friction Nitron NTR-R1 dampers take the edge off small bumps, and you can turn the adjusters softer for the drive to the track. Owners who mostly drive on rough roads may still prefer the FastRoad kit.

Are mounting brackets included with the Nitron S3 Exige S NTR-R1 ClubSport?

Yes. Mounting brackets are supplied with every Nitron S3 Exige S NTR-R1 ClubSport kit, so the coilovers mount to the S3 Exige S double wishbone suspension without sourcing extra hardware. The install stays straightforward, and everything needed to fit the dampers arrives together.

Can the Nitron NTR-R1 ClubSport damping be changed at the track?

Yes. Each Nitron NTR-R1 damper has a single adjuster that sets bump and rebound together, so changing the setup between sessions takes a few clicks per corner. You can run a softer setting on the drive in and firm the car up in the paddock, without balancing separate damping circuits.

Can the Nitron S3 Exige S NTR-R1 ClubSport be serviced and revalved?

Yes. Every Nitron S3 Exige S 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 the car moves toward competition or back toward road use, the setup can be updated to match.

Nitron NTR-R1 ClubSport Coilover Kit for S3 Lotus Exige S

Once an S3 Exige S starts running sticky track tires and doing regular circuit days, the grip it generates starts to exceed what a road-biased spring rate can control. The body leans further than it should through fast corners, and it pitches more under heavy braking than a driver chasing consistent laps wants to feel. The Nitron S3 Exige S NTR-R1 ClubSport coilover kit is aimed at exactly that owner. Its spring rates are a step stiffer than the FastRoad kit’s, which tightens body control in long, loaded corners and keeps the platform steadier as you trail-brake toward the apex. The car stays usable on the road, but the ClubSport setup clearly favors the track. One adjuster per corner sets bump and rebound together, so you can soften the car for the drive to the circuit and firm it up in the paddock with a few clicks. Mounting brackets come in the box, and the Nitron S3 Exige S NTR-R1 ClubSport mounts to the double wishbone suspension with no extra hardware to source.

Unique Technology

Inside each Nitron NTR-R1 damper is hardware taken from Nitron’s race program, much of it shared with the NTR-R3 that competes in international motorsport. Leaving off the remote canister keeps the NTR-R1 compact, which suits the tight packaging around an Exige’s wishbones. Firmer springs only work if the dampers can keep up with them. The low-friction internals of the Nitron NTR-R1 let it react quickly to the higher loads the ClubSport springs put through it, so the tires stay in contact over curbs and bumpy braking zones instead of skating across them. Fade resistance is just as important here. A light car on sticky rubber can cover a lot of hard laps, and the damping holds its setting 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 S3 Exige S NTR-R1 ClubSport kit is assembled by hand to order, with springs and valving matched to the S3 Exige S and to a track-leaning brief. That makes it a good fit for owners who drive to the circuit, run a full day of sessions on Cup-style tires and drive home again, and for cars that see more track time than road miles. Hard-anodized and titanium-finish components keep the weight down on a car built around low mass, and they also resist corrosion between seasons. As the car’s use changes, the kit can change too. Each Nitron NTR-R1 damper can be fully serviced and revalved, and the springs can be changed. If the car moves further toward competition, or back toward the road, the setup can follow rather than holding it back.

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.
