What does Nitron's Clio RS NTR-R1 Coilover Kit replace?

It replaces the springs and dampers at every corner. The passive NTR-R1 uses monotube nitrogen-pressurized dampers and race springs to cut pitching under braking and float after bumps.

How do I adjust the damping on the Clio RS NTR-R1?

Each corner has a single adjuster that moves compression and rebound together.

Do the dampers need remote reservoirs or hoses?

No. The reservoir is inside each damper, so there is nothing to mount separately and no hoses to route.

Do I get top plates with the kit?

Yes. Adjustable top plates come with the kit.

Can the spring rates be changed?

Yes. Custom spring rates are available by contacting us directly, and we can help you pick a rate for how the car is used.

Does the car need aligning after the kit goes on?

Yes. A professional alignment is required after installation.

Description

Nitron NTR-R1 Coilover Kit for X85 Renault Clio RS

The Renault Clio RS NTR-R1 Coilover Kit from Nitron replaces worn factory springs and dampers on the X85 with a passive, adjustable setup that keeps the body under control. Tired dampers show up as pitching under braking and float after bumps, and fresh springs on their own will not cure that. Nitron’s Clio RS NTR-R1 kit fits a monotube nitrogen-pressurized damper and a race spring at every corner, rear included, with a single adjuster at each wheel to set the damping the way you drive. Adjustable spring perches let you set the ride height to suit your wheels and tires, so the same kit works for a daily road car and an occasional track day.

Unique Technology

Setup is a one-dial job. Each corner has a single adjuster that moves compression and rebound together, so you turn it firmer or softer and feel the change on the next corner. The damper is a nitrogen-pressurized monotube with its reservoir inside the body, which leaves out remote hoses and any extra mounting. Ride height comes from adjustable spring perches, set to suit your wheels and tires.
- 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

Spring rate is the part owners most often want to change, because a daily road setup and a circuit setup call for very different rates. The standard rates can be changed, so contact us directly to talk through what you are building. Every kit is hand assembled to order in the UK, with dampers built for this car instead of adapted from another application. The result is a front and rear that were set up to work together.

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.
