Purpose and technical specifications

This set of spacers is intended for rims with a 5x120 bolt pattern and hubs with a 72.6 mm diameter, which corresponds to many BMW models. The 12 mm thickness per wheel allows for a noticeable widening of the track, improving the visual filling of the wheel arches and vehicle stability while maintaining reasonable interference with the factory suspension geometry.

Hubcentric spacers guide the rim along the centering ring, relieving the wheel bolts or studs. This minimizes vibrations and ensures the wheel is seated axially relative to the hub, which is particularly important at higher speeds and during dynamic driving.

Advantages of using Bimecc spacers

Using this pair of spacers allows for a technically correct and aesthetic offset of the rim from the hub. Key benefits include:

• more uniform filling of the wheel arches, which improves the car's appearance,
• increased effective track width, which can positively affect lateral stability,
• hubcentric design reducing the risk of runout and vibrations,
• the ability to fit rims with a different ET without the need for replacement.

The pair of spacers is a good solution for suspension modifications, changing to wider rims or rims with a different offset, as well as for those wanting to achieve a more assertive, sporty body line.

Product condition and installation aspects

The offered set comes from the aftermarket, which allows for an economical adjustment of wheel parameters to individual needs. Before installation, a standard inspection of the contact surfaces and mounting threads on the vehicle is recommended to ensure proper tightening of the rim to the spacer and the spacer to the hub.

When installing spacers, always use appropriately selected bolts or studs of the correct length and maintain the tightening torque recommended by the vehicle manufacturer. Proper installation is crucial for maintaining safety and the full functionality of the chassis system.

Integration with other wheel system components

Spacers from the Wheel Spacers and Centering Rings category often work in conjunction with centering rings and appropriately selected wheel bolts. In the case of rim or suspension modifications, it is worth treating them as part of a broader package of changes, including wheel alignment and tire selection.

If you are planning a comprehensive repair or upgrade of the wheel and suspension area in your BMW and need other components from the same group, such as additional spacers, centering rings, or mounting accessories, check the available parts in the Unbranded Wheel Spacers and Centering Rings category.
