How does the Nitron Elise S RacePro 3 help the car use curbs?

The Nitron Elise S RacePro 3 adjusts high-speed compression separately from low-speed compression and rebound. High-speed compression controls how the damper reacts to sharp hits, so you can let the wheels absorb a curb instead of launching the S2 Elise S. Body control through braking and cornering stays where you set it.

What does the 46mm piston do on the Nitron S2 Elise S RacePro 3?

The 46mm piston in the Nitron S2 Elise S RacePro 3 moves a larger volume of oil for every millimeter of travel. That gives the damper accurate control across the full speed range, from slow body movements to fast curb strikes. Each adjuster click also makes a clear, repeatable change, which helps when you’re fine-tuning the car.

Are mounting brackets included with the Nitron Elise S RacePro 3?

Yes. Mounting brackets are included with every Nitron Elise S 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.

How does the Nitron S2 Elise S RacePro 3 differ from the NTR-R1 kits?

The Nitron S2 Elise S 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 autocross or track days respectively.

How are the reservoirs mounted on the Nitron Elise S RacePro 3?

The Nitron Elise S 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 S2 Elise S RacePro 3 be rebuilt?

Service intervals depend on how hard and how often the car runs, and curb-heavy circuits add to the workload. Many race teams rebuild their Nitron S2 Elise S RacePro 3 dampers between seasons, or sooner on a busy calendar. 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 S

Fast laps often come down to how much curb you can use. Clip the inside of a chicane harder, or let the car run wide over the exit curb, and you straighten the line and carry more speed. Do that on dampers that can’t cope and the car gets launched, lands unsettled and loses more than it gained. The Nitron Elise S RacePro 3 coilover kit lets an S2 Elise S use the curbs properly. 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. High-speed compression controls how the damper reacts to a sharp hit, so you can let the wheel soak up a curb rather than kick the chassis into the air. Low-speed compression and rebound are set separately to keep the body controlled through braking, turn-in and exit, so softening the curb response never costs you body control. Hose-mounted reservoirs front and rear keep the compression adjusters within reach between sessions. Mounting brackets for your car’s drive side are included, so the Nitron S2 Elise S RacePro 3 fits straight into the factory double wishbone suspension.

Specialized Bi-Axis Hose Fittings

With reservoirs at both ends, the Elise S 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 swivel on two planes where each hose leaves the damper. That lets every hose on the Nitron S2 Elise S RacePro 3 point straight toward its reservoir instead of being forced into a tight bend. With drive-side brackets supplied for your car, the installation stays neat at both ends, and the hoses stay clear through full bump, full droop and full steering lock, even after repeated hard curb strikes.

Unique Technology

The Nitron RacePro 3 is built around a 46mm piston that pushes a larger volume of oil through the valving for each millimeter of shaft travel. Damping force builds accurately across the whole speed range, from slow body movements under braking to the fast spikes of a curb strike. The damper also keeps control in reserve as loads rise. Separating high-speed and low-speed compression on each reservoir is what makes curb tuning possible on the Nitron Elise S RacePro 3. You can change how the car takes a hit without changing how it rolls or pitches, and the large piston makes each click a clear, repeatable step. The hose-mounted reservoirs add oil volume away from the damper body, so damping stays consistent over a full race distance as temperatures rise.
- 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 S RacePro 3 kit is hand-built to order. Springs and valving are specified for the car’s tires, aero and series, and for the kind of circuits it races on, rather than for road comfort. That makes it the right choice for an S2 Elise S prepared for circuit racing, a dedicated time-attack build or a competition car 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. Race dampers work hard, especially on curb-heavy tracks. Every Nitron RacePro 3 unit can be fully serviced and rebuilt, and revalving for new tires, aero changes or a different series keeps the kit matched to the car season after season.

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.
