This is the MPI SimLink GT and Stock Car kit, and it transforms the Logitech G923 in a very unique way. Made by Max Papis Innovations, a company known for building real motorsport equipment, the SimLink brings some of that real world knowledge into sim racing by letting you swap rims on the G923 like you would with a proper quick release system.
In this review I will go over how the system works, what I like and do not like about it, how the GT and Stock Car rims perform, and whether it is something you should consider for your own setup.

The Logitech G923 and its older G29 and G920 siblings have been incredibly popular in the entry level sim racing space for a long time, mainly because of their attainable price. MPI clearly had that audience in mind when pricing the SimLink system.
The SimLink hub together with one wheel currently retails around 150 dollars, and additional rims are about 99 dollars each. For some people it will make more sense to save that money toward a more powerful direct drive base, but that is not realistic for everyone. Availability, total upgrade cost, or simply wanting to stick with the G923 for a few more years all play a role.
For those users, a way to modify and upgrade the existing G923 at a more manageable price can be worth considering, especially if they care about authenticity and real race car style wheels.
The SimLink itself is a simple but clever idea. Once you install the metallic center spoke on the G923, the wheel rim attaches with three thumb screws. From that point on you can swap rims in a matter of seconds without tools.
On a Logitech wheel that has always been “one fixed rim only,” that alone is a big change. It finally gives G923 owners some of the flexibility that users of higher end bases enjoy with quick release ecosystems.
A couple of important notes though:
The good news is that MPI provides a clear video guide, and once the hub is installed, you never have to touch that part again. From that point forward, swapping rims is quick and painless.

The GT add-on is modeled after the MPI wheel used in the real Audi RS3 WTCR race car. Visually it integrates nicely with the G923 and gives the entire setup a more serious, race car inspired look.
The rim is larger than the original Logitech wheel but still relatively lightweight, so it does not hurt the G923’s force feedback. On track, the detail coming through the base felt basically unchanged, which is exactly what you want with a small gear driven wheelbase like this.
The standout feature here is the “Extreme Grip RG” material on the handles. It feels similar to tennis racket grip tape, with plenty of texture and grip. Combined with the orange leather accents, hand stitched microfiber sections, and the metallic center plate, the GT rim feels purposeful and looks the part.
Despite being slightly larger, most of the G923’s buttons remained within comfortable reach, and the overall thickness of the rim felt familiar. There are also MPI branded paddle shifters behind the wheel which visually complete the package. They do not change the underlying Logitech click, and I do think adding magnets would have been a nice upgrade, but for a G923 level product it is hard to complain too much.
Overall, the GT wheel is the star of this kit for me. It adds immersion, feels good in the hands, and does not compromise the G923’s already limited torque.

The Stock Car wheel is a very different story. This rim is a large 350 mm round wheel modeled after the MPI wheels used in real stock car series. When you bolt it on, the entire setup looks and feels like a proper stock car or oval racing setup.
That realism does come with trade-offs. The wheel is slightly heavier and noticeably larger, and that pushes the Logitech G923 beyond its comfort zone. In practice, a lot of the force feedback is damped out. The low torque of the G923 simply cannot move a wheel this big effectively, so the detail, strength, and responsiveness you feel out on track drop off quite a bit.
The size also makes many of the default G923 buttons harder to reach. On a larger direct drive base, this sort of rim makes perfect sense. On an entry level Logitech, it is more of a cosmetic and immersion upgrade than a performance friendly one.
Build quality wise there is nothing wrong with the Stock Car wheel. It is hand stitched in microfiber, feels authentic, and the larger paddles match the diameter nicely. In many ways it feels like the G923 is holding the wheel back, rather than the other way around.
For that reason, I would love to see MPI bring this style of rim to more powerful ecosystems in the future, where users are both willing to pay for realism and have the torque to back it up.

All things considered, the MPI SimLink GT and Stock Car kit brings a genuinely fresh and creative twist to the Logitech G923. Being able to run real motorsport inspired rims on a budget wheelbase is something that simply did not exist before.
The GT wheel in particular offers a very nice balance of style, comfort, and immersion without sacrificing what little force feedback the G923 has. It is the option I would recommend to most people who want to upgrade the feel and look of their setup while staying on Logitech.
The Stock Car wheel is more niche. It looks and feels fantastic in the hands, but its size and weight expose the limitations of the G923’s torque and button layout. In other words, it is authentic, but probably better suited to a stronger base.
If you are a G923 owner who is not ready to jump to a new ecosystem but wants a more authentic wheel in front of you, the MPI SimLink system is a creative and worthwhile upgrade to consider.
