GEN2 Alloy Wheel Spacers Hubcentric Shims Precision BMW 5x120 72.6mm 20mm is a precision-engineered set designed for modifying the wheel track in BMW vehicles with the corresponding mounting system. Thanks to the use of hubcentric shims, you achieve a stable fitment of the wheel on the hub, which promotes confident vehicle handling and reduces the risk of vibrations. This is a solution for drivers who want to improve the visual filling of the wheel arches in a controlled manner and ensure more predictable suspension behavior.

Application and function of wheel spacers

The wheel spacers in this series allow for offsetting the wheel from the hub, which facilitates the fitment of wheel-suspension setups in BMW cars with a 5x120 bolt pattern. The design with hubcentric shims helps in correctly guiding the wheel on the hub, which is particularly important at higher speeds and when using stiffer suspension configurations.

This solution is often chosen for:

• installing wheels with a different offset than the factory specifications,
• the desire to improve wheel arch filling without interfering with bodywork,
• the need to increase clearance between the wheel and the brake caliper.

Construction and mounting parameters

The presented set belongs to the Spacers and hubcentric rings group, which means that in addition to changing the wheel's position relative to the hub, it also ensures the wheel is guided by a properly selected centering diameter. The mounting system is based on five points, which is characteristic of many BMW models with a 5x120 pattern. The applied hole diameter is matched to this type of hub, which facilitates installation and improves the repeatability of wheel positioning.

Such a combination of mounting parameters promotes:

• even distribution of loads on bolts or studs,
• maintaining the axial alignment of the wheel relative to the hub,
• reducing the risk of radial and axial wheel runout.

Performance characteristics and installation

GEN2 Alloy Wheel Spacers Hubcentric Shims Precision BMW 5x120 72.6mm 20mm is an element intended for users consciously modifying their driving geometry. A properly selected spacer thickness allows for a noticeable visual and functional change while maintaining control over the loads acting on wheel bearings and suspension components. The product is from the Unbranded group, which allows for use in various configurations without being tied to a single manufacturer's accessory line.

Before installation, it is recommended to:

• verify the compatibility of wheels and hubs in terms of bolt pattern and hole diameter,
• check the length of the mounting bolts or studs,
• inspect the contact surfaces of the hub and wheel for dirt and corrosion.

Product condition and practical application

The offered set is in used condition, which will be suitable for users looking for a functional solution on a reasonable budget. These types of spacers will work well both in daily use and in more demanding configurations where precise wheel guidance and repeatable wheel positioning on the hub are essential. Thanks to the use of hubcentric shims, typical problems associated with mounting wheels with a different offset profile than factory ones can be reduced.
