MOZA vs Logitech Mounting Holes: Which Fits Your Rig?

Why mounting pattern matters when you choose a wheel base

The mounting pattern is the arrangement of bolt holes on the underside of a wheel base. It determines whether a base sits flush on a sim rig, a wheel stand or a desk mount. If the holes do not line up, the base cannot be bolted down securely, and the force feedback torque may twist the base or damage the rig.

Every serious sim rig has a pre-drilled top plate. Most plates come with multiple hole patterns to fit several brands, but a base from one maker may sit over unused holes. The key is the distance between opposite bolts, which is usually given in the maker's manual or on a paper template included in the box.

Before buying a wheel base, measure the hole spacing on your rig or check its compatibility list. This is the same process you would use for any hardware that mounts to a cockpit or stand. For more on that, see the wheel base mounting bracket sizes article.

Logitech G mounting pattern: a wider rectangle

Logitech G wheel bases, including the G29, G920, G923 and the PRO and RS50 direct drive models, use a four-hole pattern that is wider than it is deep. The holes form a rectangle, with more space between the left and right bolts than between the front and rear bolts. This is a deliberate design that matches Logitech's original wheel stand and most third-party rigs that list Logitech compatibility.

The exact measurements are printed in the base's user manual or on a mounting template that ships with the product. Logitech's official product pages do not list the dimensions, but the manual always includes a diagram. If you are unsure, you can hold the base over the rig plate and see whether the bolt holes align.

For a full overview of Logitech's current lineup, see our best Logitech G racing wheel guide. The mounting pattern is consistent across the G series and PRO series, so if you already have a Logitech base, you can swap between models without changing your rig plate.

MOZA mounting pattern: a square

MOZA direct drive wheel bases, from the entry-level R3 to the high-torque R16, use a four-hole pattern arranged as a square. The left-right spacing is the same as the front-rear spacing, making it symmetric. This pattern is common among direct drive bases from several manufacturers, but it is not the same as Logitech's rectangle.

MOZA includes a paper template in the box for each base, and the template shows the exact hole positions. You can place the template over your rig plate to check alignment before drilling or buying an adapter. MOZA's support pages also provide a downloadable PDF for each model.

If you are choosing between MOZA and another brand, the mounting pattern is only one factor. The drive type, torque and ecosystem also matter. Our best MOZA racing wheel guide breaks down those details.

How the patterns compare side by side

The two patterns are both four-hole arrangements for M6 bolts, but they are not interchangeable because the bolt positions differ. Logitech's rectangle is longer along the steering axis, while MOZA's square is equal on both sides. A rig plate that only has a rectangular pattern will not fit a MOZA base without an adapter.

This is not a matter of one being better than the other; it is a compatibility issue. Some sim rig manufacturers include both patterns on a single top plate, which is the easiest solution. Others sell universal adapter plates that convert a Logitech pattern to a MOZA pattern or vice versa.

When you look at a rig, check whether its description mentions the exact brands it supports. Many mention both Logitech and MOZA with different hole sets. If it does not, you can always measure the holes yourself with a ruler or caliper.

Other things to check before mounting

Beyond the hole pattern, pay attention to the bolt size and thread type. Racing wheel bases typically use metric bolts, but the exact thread pitch is specified in the manual. Use the included bolts or those of the same grade to avoid stripping the threads.

The thickness of the rig plate matters as well. If the plate is too thin, the bolts may not have enough thread engagement; if it is too thick, the bolts may be too short. Check the bolt length recommendation in the base's manual.

Also consider the orientation of the base. Most bases can be mounted with the wheel facing either left or right for left-hand or right-hand driving, but the mounting pattern is the same. For more on this, read wheel base mounting orientation.

Finally, the torque you apply to the mounting bolts is important. Over-tightening can crack the base, while under-tightening allows it to move under force feedback. See the wheel mounting bolt torque spec article for general guidance.

Adapter plates and universal rigs

If your sim rig only has the Logitech pattern and you want to mount a MOZA base, you have three options: drill new holes, buy an adapter plate, or replace the rig's top plate. Drilling requires careful measurement and may void the rig's warranty. Adapter plates are a common solution because they bolt onto the existing holes and provide the second pattern on top.

Universal adapter plates are available from many sim racing accessory makers. They typically add between 5 and 10 millimeters of height, which is negligible for most setups. Make sure the adapter is made of aluminum or steel and uses the same bolt size as both the base and the rig.

Some high-end rigs ship with both patterns already drilled. If you are buying a new rig, look for one that lists compatibility with multiple brands. That way you can change bases later without buying a new plate. The direct drive racing wheel guide includes notes on mounting for many popular bases.

If you are mounting to a desk instead of a rig

On a desk, the mounting pattern is usually not an issue because the wheel base comes with a desk clamp that attaches to the bottom of the base. The clamp does not use the rig mounting holes; it grips the desk edge with a screw mechanism. Both Logitech and MOZA include a desk clamp with most of their wheel bases.

If you plan to move between a desk and a rig, verify that the clamp can be removed easily and that the base still has its standard mounting holes. A few bases have a different underside shape that interferes with aftermarket clamps, so check the manual.

For a detailed discussion of desk and stand mounting, see the mounting options: desk or stand article. Also compare how a desk clamp holds force feedback torque versus a rigid rig mount in desk clamp vs rig mount strength.

What to pick for your situation

Questions

Can I mount a MOZA base on a Logitech-specific rig plate?

Not directly. The MOZA uses a square pattern, while Logitech uses a rectangle. You need an adapter plate or a rig plate that has both hole sets.

Do all Logitech wheel bases use the same mounting pattern?

Yes. The G29, G920, G923, PRO Wheel Base and RS50 Base all share the same four-hole rectangular pattern. The manual for each model shows the exact dimensions.

What thread size do racing wheel bases use?

Most use metric bolts, but the exact size and pitch are in the base's manual. Always use the bolts provided or the recommended replacement to avoid thread damage.

Does Thrustmaster use the same pattern as Logitech or MOZA?

No. Thrustmaster has its own pattern, which differs from both. Check the specific base model's manual or support page for hole spacing.

Can I drill new holes in my sim rig to fit a MOZA base?

Yes, if the rig is made of steel or aluminum. Drill carefully, measure twice, and deburr the edges. If the plate is painted or plastic, drilling may damage it or void the warranty.

Where can I find the official mounting diagram for a MOZA base?

MOZA includes a paper template in the product box, and the support pages on the MOZA website provide downloadable PDFs for each base model.
