ND Gauge Kit Guide
Thanks for your interest in the ND Gauge Kit. Before placing an order, please take a moment to read this guide so you can choose the correct version for your car and enjoy it with confidence.
Overview
Why we built this kit
This gauge kit is based on products we have been developing for ND Roadster (MX-5/Miata) owners in Japan.
One overseas owner accidentally purchased our Japan-spec 200 km/h version, fitted it to his car, and posted the photos on Instagram. The response from ND owners around the world was far greater than we had ever expected.
For many years we had already received requests for a version that matched local speedometer scales and could be used long-term. In this particular case, however, there was also a strong feeling that we wanted to help the owner who had bought the wrong kit by mistake.
As a result, we decided to create dedicated layouts for 240 km/h and 140 MPH clusters, using the same stainless-steel construction we have been refining for the Japanese market over many years.
Key features of this kit
Compatibility
Model years
This kit is available in two main versions:
• For 2015–2023 models
• For 2024– facelift models
If you are not sure which version your car belongs to, please compare your cluster with the image in this guide.
The easiest way to tell is the diameter of the needle base (the round hub at the centre of each gauge).
On 2015–2023 cars this part is larger, while on 2024– facelift cars it is clearly smaller.
Cluster types
In addition, Mazda used two types of instrument clusters:
• Type A: with full-color TFT multi-information display
• Type B: with monochrome LCD only
When ordering, please make sure that both of the following match your actual cluster:
• Model year (2015–2023 / 2024–)
• Cluster type (Type A / Type B)
For 2024– facelift models, Mazda currently supplies the cluster only with a full-color TFT display. For that reason, this kit for 2024– cars is designed only for Type A (full-color TFT) clusters.
Choosing the correct scale
This kit is available in three speedometer scales:
• 240 km/h – for clusters with a 240 km/h maximum
• 140 MPH – for mph clusters that read up to 140 mph
• 200 km/h – for clusters with a 200 km/h maximum (mainly Japan-spec cars)
The basic rule is simple:
Always choose the same scale as the factory speedometer currently fitted to your car.
If you fit a 200 km/h dial to a 240 km/h cluster, or a km/h dial to an mph cluster, the indicated speed will no longer match the actual speed.
If you are unsure which scale your car has, please check the following before ordering:
• The maximum value printed on your speedometer
• Whether the unit is km/h or mph
• For imported cars, which cluster was installed by the previous owner or seller
What changes – and what does not
This kit is designed so that the original instrument cluster can be reused as much as possible.
Parts that change with this kit
• The main dial designs for the speedometer and tachometer
• The stainless-steel front panel
• The design of some warning and indicator icons (for example, the car silhouette is changed to match the ND)
• The way light is diffused across the dial surface and how the illumination appears
Parts that do not change
• The original circuit boards and sensors
• The odometer reading and stored vehicle data
• CAN communication and the control logic for warning lamps
• The basic accuracy of the speedometer, as long as the correct scale is selected
In other words, this kit is not the kind of product that rewrites or modifies the electronic control system.
Its purpose is to rebuild the visible hardware and the way it is lit, in order to improve what you see and feel while driving. At the same time, in everyday use the cluster is intended to behave just like the factory unit.
Installation and support
This kit is intended for careful DIY owners who are used to working with interior trim and plastic parts, or for trusted professional workshops.
The work involves removing the cluster from the dashboard, taking the needles off once, and replacing the original dial faces and panels. That may sound difficult, but in Japan we have already supplied this kit to more than 1,000 general users. In other words, the included instructions are written to be understandable even for non-professionals, and the video guide has also been well-received.
To make installation as clear as possible, the kit includes:
• A detailed printed installation manual
• A dedicated tool set for safely removing the needles
• A QR code linking to a step-by-step installation video
With the right tools and enough time, many owners will be able to complete the installation themselves.
However, if you feel unsure at any point, we strongly recommend asking a trusted workshop or technician to perform the work rather than forcing yourself to continue.
If any problem occurs during installation and the cluster stops working correctly, we also offer a repair support service.
In many cases, issues can be resolved simply by checking the steps together over email.
If the needles have been damaged or installed incorrectly, however, the cluster may need to be repaired. In that case:
• You send the complete cluster to us
• We inspect it, repair it as far as possible, and re-install the kit
• You pay only the round-trip shipping cost – we do not charge a labour fee for the repair
If you would like to use this support, please contact us before shipping the cluster. We will advise you on how to pack and send it safely.
