2022 BMW X4M needs to buy extended wheel bolts to match after installing the slip-on wheel spacers, BONOSS provides the split type and one piece extended wheel bolts for customers to choose from, it is not recommended to use the stock wheel bolts after installing the slip-on wheel spacers, because the thickness of the wheel spacers increases the distance from the brake rotor hat to the wheel bolt hole, it needs longer bolts to lock the wheel. Some customers may question whether stock wheel bolts can be installed in the same location, but why can’t they be used? The reason is that the stock wheel bolts are still unable to bite into the threads of the brake rotor hat to reach the standard number of turns after installation, and cannot ensure that the wheel is in a concentric position with the hub assembly when receiving feedback from the road.
