Does Nitron’s F56 MINI Cooper NTR-R1 Coilover Kit fit the Cooper S, Cooper SE, JCW, and JCW GP as well?

Yes. This Nitron kit is made for the F56 MINI Cooper, Cooper S, Cooper SE, JCW, and JCW GP, and covers the front and the coilover rear.

Do different F56 models need different spring rates?

They can. The F56 range runs from a light Cooper to the heavier electric Cooper SE and the higher-output JCW and JCW GP. Custom spring rates are available by contacting us directly if the standard rates do not suit your car and how you use it.

What does the single adjuster on each damper change?

It raises or lowers compression and rebound resistance together. Turning it toward firm tightens the car’s response when you brake, turn in, and accelerate, and backing it off softens the ride over rougher surfaces.

How do I set ride height and corner weights?

Each damper has adjustable spring perches, so every corner can be raised or lowered independently. That gives you the overall height and the balance across the four wheels, and a corner weighting session will confirm the result.

How does the kit handle the coilover rear suspension?

The rear uses a coilover layout, and the kit is built for it. The Nitron spring and damper replace the factory parts at the rear in the same position as the originals.

Do I need an alignment after fitting the kit?

Yes. Adjustable top plates are included, and a professional alignment is required after installation so the new ride height and any camber changes are set correctly. The F56 MINI Cooper NTR-R1 is best paired with a proper setup session.

Description

Nitron NTR-R1 Coilover Kit for F56 MINI Cooper, Cooper S, Cooper SE, JCW, and JCW GP

The F56 MINI Cooper NTR-R1 Coilover Kit from Nitron gives F56 owners one dial per corner, so the car can be firmed up for hard driving and backed off again for the road. Each damper is a nitrogen-pressurized monotube that adjusts compression and rebound together, with adjustable spring perches for ride height and corner weights, and the rear uses a coilover layout. The F56 range covers a wide spread, from a light Cooper to the John Cooper Works (JCW) and JCW GP and the heavier electric Cooper SE, and a damper with simple, repeatable adjustment suits that variety. It is a good fit for a driver who wants the car sharper on back roads or at an occasional track day without having to work through a complicated setup.

Unique Technology

The NTR-R1 is built around a single decision per corner. One adjuster moves compression and rebound resistance together, so the car gets firmer or softer in clear steps and the effect of each change is easy to feel. The reservoir is internal, which means no remote canisters and no hoses to route in a small engine bay and wheel arch. Inside is a monotube damper pressurized with nitrogen, hand assembled to order in the UK, and fitted with race springs. Custom spring rates can be arranged by contacting us directly, which helps given how much weight varies across the F56 range.
- 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 builds this kit around the F56 chassis, with damper length, stroke, and perch positions set for the car instead of reworked from a universal part. The front and the coilover rear are both matched to the car, so the spring and damper at each end work together. The same kit covers the whole range of F56 models, and spring rate is the main variable between a Cooper and a JCW GP or a Cooper SE, which is why the custom rate option matters.

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.
