The 2022 BMW M4 spacers can be divided into hub-centric wheel spacers and lug-centric wheel spacers in terms of whether or not to change the load-bearing structure of the axle hub. The hub-centric wheel spacer has a ring step, which can tightly connect the wheel hub and the axle hub because the ring step center bore is precisely designed for each vehicle model. When the wheel rotates, the wheel hub and the axle hub are still a whole, and the downward sheer force of the vehicle is still transmitted to the axle, which is also the original loading structure designed by the auto manufacturer.
The lug-centric wheel spacer has no ring step, and its center bore is generally very large. In this way, it can match the center bore of most vehicles, improving the matching range of the model, but it is not precise. Without the connection structure between the axle hub and the wheel hub, most of the weight will be borne by the wheel studs. This is very easy to cause the studs and lug nuts to break.
In any case, we don’t want you to use lug-centric M4 spacers. This kind of design structure is really unsafe. Generally, you can only see such a design structure on low-quality spacers. We hope you choose M4 spacers with a hub-centric design as the standard, which ensures that your vehicle maintains the original loading structure, and installing the hub-centric 2022 BMW M4 spacers just like adding a slice of cheese to your burger which is icing on the cake.
