Does the FL5 Civic Type R require the Electronic Damping Delete Kit?

Yes. The FL5 Type R came equipped with adaptive dampers as standard, and fitting a non-electronic coilover kit without addressing that system will trigger fault codes and warning lights. The Nitron Electronic Damping Delete Kit is required alongside this kit to prevent those faults and is available separately.

Is the NTR-R1 the right choice for track use, or should I be looking at the NTR-R3?

The NTR-R1 covers serious track use without compromise; it shares core components with a kit built for professional competition and the hardware behind the combined adjustment is the same quality as the R3. The difference is interface, not capability. If you need fully independent high and low speed compression control to dial in setup across different circuits, the R3 is the step up. If combined adjustment suits your approach, the R1 is the correct kit.

How does combined 2-way adjustment work on the NTR-R1?

Compression and rebound are adjusted together through a single 24-click range rather than independently. It keeps the setup process straightforward without sacrificing the quality of the hardware making those adjustments, and covers a wide range of road and track conditions within that range.

Is this kit fully serviceable long term?

Yes. Every NTR-R1 is hand-built to order and fully serviceable, so replacement parts and rebuild services are available through Nitron's service network well beyond the initial purchase.

Can I run custom spring rates?

Yes. Recommended rates are available for both Fast Road Spec and Track Day Spec configurations, but custom spring rates are available on request.

Description

Nitron NTR-R1 Coilover Kit for FL5 Honda Civic Type R

The FL5 Civic Type R arrives with genuine performance credentials, but there’s still room on the table when the road tightens up or a track day pushes the car harder than the factory setup was calibrated for. The Nitron NTR-R1 addresses that directly with precision-engineered combined 2-way damping adjustment drawn from the R3 race platform, sharing core components with a kit developed for professional competition. Every unit is individually hand-built with ultra-low friction components that hold damping consistent and fade-resistant whether the car is on the street or deep into a circuit session, and with each kit custom built, custom sprung, and fully serviceable, it’s an investment that holds up well beyond a single season.

Unique Technology

Nitron builds every shock around precision components that go through a thorough design and development process long before final assembly. The modular construction gives engineers the room to develop each application properly on its own terms, without cutting corners on part quality or how components work together under load. Everything is machined to tight tolerances and inspected individually by trained technicians; quality control isn’t a final step here, it runs through the entire process. New materials, finishes, and processes are validated extensively before they’re brought into production, with proprietary Nitron technologies woven throughout to produce shocks that hold up against the competition on both road and track. That level of engineering discipline is what the brand has been built on.
- 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 start with a generic damper and work backward from there. Every application is developed from the ground up, with components, spring rates, and damping characteristics determined by the specific platform rather than borrowed from something adjacent. The geometry, weight distribution, and suspension travel of the FL5 Civic Type R shape the design from the start, not as corrections added later. That’s what separates a kit engineered for this car from one that was simply made to fit it.

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.
