When I decided to replace my stock Miata steering wheel with a smaller sport aftermarket wheel, I opted to use a Momo steering wheel hub for Miata for the installation. Since Momo is the only company that I\u2019m aware of that makes a crushable hub I was adamant about it.<\/h3>\n

The steering wheel hub, otherwise know as the boss hub or steering wheel boss, is a necessary part for installation of an aftermarket steering wheel in a car previously equipped with a stock airbag type steering wheel. A crushable or collapsible steering wheel hub will crush under impact to absorb a bit of the force if you happen to smack it with your body during an accident. Since I\u2019m removing the stock airbag, I figured I would add this little bit of security. Mind you, I don\u2019t know how much it would really help, but on paper, the concept of a collapsible hub makes sense.<\/p>\n

However, upon searching the internet for information on the MOMO hub adapter I realized I couldn\u2019t find a decent picture or set of dimensions for the MOMO steering wheel hub specifically for Miata. I decided then to snap a bunch of good photos and include dimensions for those of you that might be interested in using one for your Miata. The photos are beautiful, aren’t they?<\/p>\n

One thing I discovered is that at 2.25 inches \/ 57mm, the MOMO Miata steering wheel hub is actually very slim compared to other popular hubs for Miata such as Works Bell and Daikei hubs. This makes it so that it’s super important to be aware of the height of the hub. Barring really deep dish steering wheels, with most aftermarket steering wheels from MOMO, Nardi, Personal and NRG, if your intention is to use the MOMO hub alone you will end up with the steering wheel too far from you – further than stock. This might be OK for the giants that want to drive Miatas (Miatae, for the really geeky), but for most of us it will actually hinder driving performance.<\/p>\n

To set a baseline remember this:<\/strong><\/p>\n

The stock steering wheel in a Miata NA (1990-1997) is exactly 5\u201d \/ 127mm from the plastic base of the steering column to the outer edge of the stock steering wheel (the top edge, closest to you).<\/p>\n

So basically, your goal with the aftermarket wheel is that after stacking the parts together, you would likely want to be near stock position, or a bit closer to you for a more sport-oriented driving position.<\/p>\n

Of course, this is just a rule of thumb. The really tall guys with huge long arms might want to push the steering wheel slightly away. Those that are very worried about having removed the airbag might also want the steering wheel even further away.<\/p>\n
