Which cars does the Nitron R56 MINI Cooper NTR-R1 Coilover Kit fit?

The R56 MINI Cooper, Cooper S, JCW, and JCW GP, and covers the front and the OEM rear suspension.

Is the MINI Cooper NTR-R1 comfortable enough for daily driving?

It can be. The single adjuster at each corner can be backed off toward soft for everyday roads and turned toward firm for spirited drives or track days, so one set of dampers covers both.

How does the kit fit with the OEM rear suspension?

The rear keeps its original OEM suspension layout. The kit is built to suit that arrangement, so the Nitron spring and damper replace the factory parts in the same place.

How do I set ride height and corner weights?

Adjustable spring perches on each damper let you raise or lower every corner independently. That gives you the overall height and the balance across the four wheels, and a corner weighting session will confirm the result.

Can I order other spring rates for my R56?

Yes. Custom spring rates are available by contacting us directly, which is worth considering if the car is used mainly on track or has been modified in ways that change its weight.

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 Nitron R56 MINI Cooper NTR-R1 is best paired with a proper setup session.

Description

Nitron NTR-R1 Coilover Kit for R56 MINI Cooper, Cooper S, JCW, and JCW GP

The Nitron R56 MINI Cooper NTR-R1 Coilover Kit is for R56 owners who drive their Cooper, Cooper S, JCW, or JCW GP every day and still want it to handle better when the road gets interesting. Most of these cars do double duty as commuters and weekend fun, so Nitron’s MINI Cooper NTR-R1 keeps the adjustment simple, with one dial per corner that moves compression and rebound together. Adjustable spring perches set ride height and corner weights, and the OEM rear suspension type is retained, so the car keeps its original layout while gaining dampers you can tune. For an R56 that needs to stay comfortable on a Monday and sharper on a Saturday, the MINI Cooper NTR-R1 is a practical way to get both.

Unique Technology

The NTR-R1 is built to be easy to live with. One adjuster at each corner raises or lowers compression and rebound resistance together, so you can firm the car up for a spirited drive and back it off for a bad road without learning a complicated procedure. The reservoir is built into the damper body, so there are no remote canisters or hoses to mount. Inside is a nitrogen-pressurized monotube, hand assembled to order in the UK and paired with race springs. It is a passive design, which keeps the MINI Cooper NTR-R1 simple, durable, and easy to repeat from one setting to the next.
- 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 the MINI Cooper NTR-R1 around the R56 chassis, with damper length, stroke, and perch positions set for the car instead of reworked from a universal part. The rear stays as the OEM suspension type, and the Nitron spring and damper package goes into that layout. The factory geometry is left in place, and the front and rear gain adjustment the original dampers never had.

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.
