Is it time to replace your race suit? Let’s get you track-ready. Top Steering Wheel and Boss Kit Recommendations for the Mazda MX5 Mk2
The Mazda MX5 Mk2 continues the spirit of the original with its lightweight chassis, sharp steering, and pure driving feel. It’s a favourite among driving enthusiasts for good reason, and one of the best ways to personalise and sharpen your connection with the car is by upgrading the steering wheel. Whether you’re looking to improve feedback, get a more aggressive driving position, or just want something that looks and feels better, swapping the factory wheel makes a big difference.
To make the change properly, you’ll need a boss kit that’s designed to fit the Mk2’s steering column precisely. That’s where the MOMO Mazda MX-5 Miata (1989–2005) Steering Wheel Boss Kit comes in. This kit is a direct fit for the Mk2 and provides a standard 6x70mm bolt pattern, so it works with most aftermarket wheels from brands like MOMO, OMP, Sparco, and Sabelt.
Using a genuine MOMO boss kit means the installation is straightforward and reliable. There’s no cutting, drilling, or guesswork. Just bolt it on, and you’re ready to go. It’s the same setup we’ve recommended to customers in-store for years, whether their MX5 is a daily driver or a dedicated track car.
For Mk2 owners looking to upgrade their interior and driving feel, this is the easiest way to open up a world of aftermarket steering wheel options while keeping everything safe, secure, and road or track ready.
Why a Boss Kit Is Essential
If you’re planning to fit a motorsport or performance steering wheel, the first thing you’ll need is a proper boss kit. This part connects the new wheel to your car’s steering column and provides a solid, safe mounting point. On the steering wheel side, it uses a universal 6-bolt pattern, which means it’s compatible with most aftermarket wheels on the market.
Thanks to this shared bolt layout, you can pick from a wide range of steering wheels without having to worry about whether they’ll fit. Whether you’re building a track-focused car or just want to refresh your interior with a better driving feel, a good boss kit gives you the flexibility to choose the setup that suits your car and how you like to drive.
A boss kit, sometimes called a hub adapter, is the component that makes it possible to install an aftermarket steering wheel on your car. Factory steering wheels are often large and designed for comfort rather than feedback, whereas a motorsport style wheel is built to offer better grip, sharper inputs, and a more engaging driving experience.
Choosing a MOMO boss kit brings a number of clear advantages:
- Precise fit and compatibility, as each kit is designed specifically for the vehicle it is intended for
- High quality construction using durable, lightweight materials for long term reliability
- Improved steering feel by reducing unwanted flex and increasing responsiveness
- Wide compatibility with popular aftermarket steering wheels from brands such as MOMO, OMP, Sparco, and Sabelt
- Support for essential vehicle functions, with resistors or wiring included where required to manage vehicle electronics
Whether the goal is a dedicated track build, a performance-focused road car, or a clean show car setup, a boss kit is a key component in creating a steering wheel upgrade that improves both how the car feels to drive and how it looks inside.
The MOMO Boss Kit for Mazda MX5 Mk2 (1989–2005)
Our top choice and the only boss kit we currently recommend for the Mk2 MX5 is the MOMO Mazda MX-5 Miata (1989–2005) Steering Wheel Boss Kit. This kit is designed specifically to suit the first-generation MX5, ensuring a proper fit to the factory steering column without the need for modification.
This MOMO boss kit has a dual-pattern design: on one side, it fits the Mazda MX5 Mk2 steering column; on the other side, it provides a universal 6x70mm PCD bolt pattern that works with most aftermarket steering wheels, including MOMO, OMP, Sparco, and others.
This means you get maximum flexibility when choosing your wheel and full compatibility with quick-release systems too. It’s made to MOMO’s high-quality standards and provides a solid, vibration-free interface between the steering wheel and your car.
Key Features:
- Designed for Mazda MX5 Mk2 (1989–2005)
- Compatible with most 6-bolt aftermarket steering wheels

Choosing a Steering Wheel for Your MX5 Mk2
With the boss kit sorted, the next step is picking the right steering wheel. Most MX5 drivers go for a 330mm or 350mm wheel, depending on driving style and interior space.
- 330mm wheels feel sharp and responsive, great for track setups or tighter cockpits.
- 350mm wheels offer a bit more leverage and are a good match for road-focused builds.
We recommend sticking with trusted brands like MOMO, Sparco, OMP, and Sabelt. These all use the 6x70mm bolt pattern that fits directly to the MOMO boss kit. Materials range from classic leather to high-grip suede, and wheel designs include flat or dished profiles depending on how close you want the wheel.
Once you’ve got your boss kit for your MX5, the next step is selecting the perfect aftermarket steering wheel. We have an extensive range of high-performance steering wheels from top brands like:
- OMP – Lightweight designs built for racing precision.
- Sparco – Stylish and functional wheels for both road and track.

Steering Wheel Installation Explained
So how can steering wheels from brands like MOMO, Sparco, and OMP all work with the same Mazda MX5 Mk2 boss kits? It comes down to the universal 6 point bolt pattern that these brands use across their steering wheel ranges.
The vast majority of aftermarket motorsport and classic style steering wheels, including all MOMO, Sparco, Sabelt, and OMP wheels we supply, use a 6 bolt mounting pattern on a 70 mm diameter circle. This is commonly referred to as a 6×70 PCD and has become the industry standard. Because this pattern is shared, steering wheels from different brands all mount in exactly the same way.
This makes choosing a steering wheel far simpler. Once you have the correct boss kit for your vehicle, you are free to select a steering wheel based on design, size, and driving feel rather than worrying about compatibility. The wheel attaches to the boss kit using six evenly spaced bolts, and because the spacing is standardised, mixing brands is not an issue. For example:
- A Sparco steering wheel will bolt straight onto a MOMO or B-G boss kit
- An OMP wheel fits perfectly onto a MOMO hub designed for Mazda MX5 Mk2.
- A quick release from one brand can be used with a steering wheel from another, as long as they share the 6×70 bolt pattern
All of the quick-release kits we offer also use this same 6-point bolt pattern on both sides. The quick-release sits between the Mazda MX5-specific boss kit and the steering wheel, with one side bolting to the boss and the other side bolting to the wheel. Because both sides use the same pattern, installation is clean and straightforward with no alignment issues.
There are a small number of alternative bolt patterns in the steering wheel world, such as the slightly larger 6×74 pattern used by some Nardi and Personal wheels. However, almost all MOMO, Sparco, OMP, and B G products use the 6×70 pattern. By sticking with these brands and our extensive Mazda MX5-focused boss kit range, you can be confident that every component will work together properly without the risk of mismatched parts.
Why Not Add a Steering Wheel Quick Release Kit.
When installing an aftermarket steering wheel and boss kit, many drivers also choose to add a quick release kit to complete the setup. A quick release sits between the steering wheel and the boss kit, exactly as shown in the diagram earlier in this guide. It allows the steering wheel to be removed and reattached in seconds, creating a more flexible and practical interior setup.
There are several reasons drivers choose to run a quick release system. In motorsport builds it can make entering and exiting the car easier, especially in vehicles with tight cockpits, roll cages, or fixed bucket seats. It can also add an extra level of security, as removing the steering wheel when the car is parked makes it much harder for the vehicle to be driven away.
Our quick-release kits share the same universal 6-point bolt pattern used by the majority of aftermarket steering wheels and boss kits. This makes them very easy to integrate into an existing setup without needing special adapters. The quick-release simply bolts between the steering wheel and the boss kit, maintaining the same mounting system used across most performance steering wheel brands.
For customers looking for a reliable option, we recommend the B G Racing universal quick-release boss kit. It is a solid and well-engineered option that avoids the movement or knocking that cheaper quick-release systems can develop over time. The fitment is tight and secure, making it a dependable choice for both road cars and motorsport builds.
