Why does adjuster repeatability matter on the Nitron 111R RacePro 3?

Race teams build a setup book from each circuit and session, and it only works if the same adjuster settings produce the same result every time. The Nitron 111R RacePro 3 uses a 46mm piston with independent rebound, low-speed compression and high-speed compression. Each click makes a defined, repeatable change you can log and return to.

Are mounting brackets included with the Nitron Elise 111R RacePro 3?

Yes. Mounting brackets are included with every Nitron Elise 111R RacePro 3 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 mount the coilovers and reservoirs to the factory double wishbone suspension.

Does the Nitron 111R RacePro 3 fit both the Elise 111R and Elise R?

Yes. The Nitron 111R RacePro 3 fits the S2 Lotus Elise 111R and the later Elise R. Each kit is sprung and valved to order for the car’s tires, aero package and series. K-series S2 Elise models use their own Nitron RacePro 3 kit, so check your engine before ordering.

How does the Nitron Elise 111R RacePro 3 differ from the NTR-R1 kits?

The Nitron Elise 111R RacePro 3 is the full-race kit, built around a 46mm piston with independent 3-way adjustment and remote reservoirs. The Nitron NTR-R1 FastRoad and ClubSport kits use a single combined adjuster and no reservoirs, with spring rates aimed at road driving and track days respectively.

How are the reservoirs mounted on the Nitron 111R RacePro 3?

The Nitron 111R RacePro 3 uses hose-mounted reservoirs at both ends, each connected to its damper by a hose. Nitron’s Bi-Axis fittings let each hose leave the damper at the correct angle, so routing past the wishbones, ducting and bodywork stays clean. Plan the reservoir locations so the adjusters are easy to reach between sessions.

How often should the Nitron Elise 111R RacePro 3 be rebuilt?

Service intervals depend on how hard and how often the car runs. Many race teams rebuild their Nitron Elise 111R RacePro 3 dampers between seasons, or sooner on a busy calendar, to keep them performing exactly as recorded in the setup book. Revalving can be done at the same time if your tires, aero or series change.

Description

Nitron RacePro 3 Coilover Kit for S2 Lotus Elise 111R / R

Serious race programs work from a setup book. That’s a record of what the car ran at each circuit, what changed between sessions, and what the stopwatch and data said about it. A setup book is only useful if the car responds the same way every time, and the Nitron 111R RacePro 3 coilover kit is built for that level of precision. It’s built to Nitron’s full-race specification around a 46mm piston, with independent rebound, low-speed compression and high-speed compression at every corner. Each circuit has its own adjuster, each click produces a defined and repeatable change, and each change can be logged and carried back to the same track next season. You can start a weekend from a known baseline, adjust one circuit at a time and see exactly what each change did to lap time, without guessing which part of the setup caused it. Hose-mounted reservoirs front and rear keep the compression adjusters easy to reach between sessions. Mounting brackets for your car’s drive side are included, so the Nitron Elise 111R RacePro 3 fits the factory double wishbone suspension of both the 111R and the later Elise R.

Specialized Bi-Axis Hose Fittings

With reservoirs at both ends, the Elise 111R has four hoses that each need a secure route past the wishbones, brake lines, ducting and bodywork. That route also depends on which side the car is driven from. Nitron’s exclusive Bi-Axis fittings pivot on two planes where each hose leaves the damper. That lets every hose on the Nitron Elise 111R RacePro 3 point directly toward its reservoir instead of being forced into a tight bend. With the drive-side brackets supplied for your car, the installation stays tidy at both ends, and the hoses stay clear through full bump, full droop and full steering lock.

Unique Technology

The 46mm piston at the heart of the Nitron RacePro 3 moves a larger volume of oil through the valving for every millimeter of shaft travel. Damping force builds accurately, and the damper keeps control in reserve as loads rise under braking and through fast corners. That accuracy is what makes the adjusters trustworthy. A given number of clicks on the Nitron 111R RacePro 3 produces the same change in damping force today as it will next season, so the numbers in your setup book keep their meaning. The hose-mounted reservoirs add oil volume away from the damper body, which keeps damping consistent over a full race distance as temperatures climb. High- and low-speed compression adjust independently at each reservoir, and rebound adjusts at the damper. That gives you the separation you need to isolate one variable at a time.
- 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 111R RacePro 3 kit is hand-built to order, with springs and valving specified for the car’s tires, aero package and series rather than for road comfort. It suits an Elise 111R prepared for circuit racing, a dedicated time-attack build or a car set up for sprints and hill-climbs on slicks. Hard-anodized components and titanium hardware keep weight down on a car built around minimal mass, and they resist corrosion through wet race weekends and winter layups. For a race team, consistency also means maintenance. Every Nitron RacePro 3 unit can be fully serviced and rebuilt back to its original performance, and it can be revalved for new tire compounds, aero changes or a different series as the program 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.
