Adding an aftermarket steering wheel not only look great but it can be functional. By adding a smaller diameter steering wheel, it creates a sharper steering response, which we enthusiasts seem to enjoy as you feel more connected to the road. Aftermarket steering wheels also allow you to add quick disconnects which are key in track or race cars to make it easier for the driver to get in and out of the racing seat.

There are so many options out there between steering wheel brands, mounting hubs, and quick releases, and unfortunately, there is no standard for the bolt pattern. That being said there are two brands that have seen to take the market and offer some sort of standard. These are Nardi and MOMO.

To mount the steering wheel to the hub, there are usually 6 to 8 countersunk bolts that do this. Many manufacturers have a different pattern of how these are laid out. This is called the pitch circle diameter or PCD. This is the imaginery line that passes through the center of the circle. This is usally measured in millimeters. PCD is also used on wheel bolt patterns, which you are probably familiar with (4x100, 5x120, 5x112 etc).

What does all this mean? It means you will have to do a little research when adding an aftermarket steering wheel to your car. We created an easy guide below to help you pick out the right hub and quick release depending on what steering wheel manufacturer you buy.

If you have one or the other, they do make adapters to allow you to switch to the new bolt pattern. Please see the Amazon Link below
