How does the adjustment work?

A single knob controls compression and rebound simultaneously across 24 clicks of combined adjustment. Turn it toward firm for more aggressive driving, back it off for everyday road use. There is no need to manage two separate dials.

How do the spring rates compare to the factory setup?

Nitron recommends 400lbs/inch front and 500lbs/inch rear for the Type 122 Evora in FastRoad specification. The rates are road-biased but stiffer than stock, reducing body movement and improving chassis response without turning the car harsh on the road. Custom rates are available if your use case calls for something different.

Can it be serviced or upgraded later?

Yes on both. Every Nitron NTR shock is fully disassembleable and can be revalved or rebuilt. The R1 FastRoad can also be upgraded to ClubSport or custom specifications down the road without starting over.

Description

Nitron NTR-R1 FastRoad Coilover Kit for 122 Lotus Evora

The Nitron NTR R1 FastRoad Coilover Kit for the Type 122 Lotus Evora is built for drivers who want to pull more from the factory chassis without trading away the ride quality that makes the Evora work on real roads. The Type 122’s platform already has strong bones; this kit sharpens what’s there, not just lowers it. Four 1-way adjustable dampers with a single knob controlling combined compression and rebound keep setup straightforward, while the road-biased spring rates, sports valving, and lowered ride height work together to reduce body movement and tighten up the Evora’s responses without turning it harsh. The R1 sits at the entry point of Nitron’s NTR range, but it shares design DNA with the R3 system used in full race builds, and every unit is hand-built to order using titanium and hard-anodised components that resist corrosion and hold up through winter driving and extended track sessions without fade. Inverted shock construction reduces unsprung mass, the kit ships preset with bearing spacers ready to bolt on, and the whole thing is fully serviceable and upgradeable.

Unique Technology

Nitron doesn’t build a generic shock and machine it down to fit the Type 122. Every component, spring rate, and damping characteristic in this kit is engineered around the Evora’s specific geometry, weight distribution, and suspension travel from the start. That work happens before final assembly, not after the fact. Each unit is machined to tight tolerances, inspected individually by trained technicians throughout production, and validated against Nitron’s own proprietary standards before it ships. That process hasn’t changed 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 122 Lotus Evora. Every application goes through a dedicated development process, with components, spring rates, and damping characteristics engineered around the Evora’s platform rather than the broader sports car category it belongs to. Geometry, weight distribution, and suspension travel are factored into the design from the start, not compensated for after the fact. The result is a kit built specifically for the Evora, not one that was built broadly and happens to fit.

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.
