How does the R3 ClubSport differ from the R3 FastRoad?

The 3-way adjustment architecture is the same across both; 16 clicks of high compression, 26 clicks of low compression, and 24 clicks of rebound, all independent. The ClubSport runs stiffer spring rates and track-focused valving where the FastRoad uses softer rates with road-biased tuning. The ClubSport is the right choice if the car is primarily on circuit; the FastRoad if there is meaningful road use in the mix.

How does separating high and low speed compression actually change what you can do with the setup?

High speed compression controls how the damper responds to sharp, sudden inputs; curbs, bumps, surface changes. Low speed compression governs body motion through corners, braking, and acceleration. Adjusting them independently means you can address one without disrupting the other, which gives you the precision to dial in a specific characteristic at a specific circuit without unintended consequences elsewhere in the setup.

Can the spring rates be changed from the recommended spec?

Yes. Every R3 ClubSport kit is custom built to order, and custom spring rates are available if your setup or use case calls for something different.

Description

Nitron NTR-R3 ClubSport Coilover Kit for 131 Lotus Emira (with V6)

The Nitron NTR R3 ClubSport Coilover Kit for the Type 131 Lotus Emira V6 is built for drivers who run the car seriously on track and need the adjustment range to develop the setup properly across different circuits and conditions. Stiffer springs and track-focused valving put chassis control and on-circuit consistency first, while independent 3-way damping adjustment with separate high and low speed compression control gives the precision needed to address specific handling characteristics without trade-offs. A large diameter piston and ultra-strong piston rod provide the damping control and chassis feedback that serious setups depend on, and that the Emira V6’s mid-engine balance rewards when the suspension is dialed in correctly. Piggyback reservoirs front and rear keep high and low speed compression adjustment accessible at both ends without adding complexity to the installation. The R3 is a proven race winner with lap records across a wide range of international motorsport formulas, and every kit is custom built, custom sprung, and fully serviceable.

Unique Technology

Nitron builds every shock from precision components that go through a thorough design and development process long before final assembly. The modular construction gives engineers the flexibility to approach each application on its own terms without cutting corners on part quality or how components perform together under load. Everything is machined to tight tolerances and inspected individually by trained technicians; that quality control runs through every stage of production rather than being concentrated at the end. New materials, finishes, and processes are validated extensively before adoption, with proprietary Nitron technologies integrated throughout to produce shocks that consistently hold up against the competition on road and track. That engineering standard is what the brand has been built on since 1998.
- 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 adapt a generic damper to fit the Type 131 Lotus Emira V6; they engineer one around it. Every application goes through a dedicated development process where components, spring rates, and damping characteristics are determined by the specific platform, not borrowed from something close enough. The geometry, weight distribution, and suspension travel of the Emira V6 are part of the design from the beginning, not corrections introduced later. That’s the difference between a ClubSport kit built for this car and one that was simply developed for a category it happens to fall into.

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.
