GEN2 Alloy Wheel Spacers Hubcentric Shims Audi 5x112 66.6mm 20mm are precision, hubcentric wheel spacers designed for wheels with a 5x112 bolt pattern and a 66.6 mm center bore. By increasing the wheel offset from the hub by 20 mm per side, they allow for a more aggressive wheel stance, improved stability, and an aesthetically pleasing filling of the wheel arch. This is a solution for Audi drivers who expect consistent handling, better track width, and predictable suspension behavior.

Purpose and function of the spacers

The presented spacers belong to the Wheel spacers and centering rings category and have been designed for the running gear of Audi vehicles with a 5x112 bolt pattern and a 66.6 mm hub. The hubcentric design means that the spacer transfers loads through the hub rather than solely through the bolts, which promotes stable handling and reduces the risk of steering wheel vibrations at higher speeds.

The 20 mm thickness allows for a noticeable widening of the track, which translates into:

• more confident vehicle behavior in corners,
• better wheel arch filling with wider wheels,
• increased clearance between the wheel and suspension or braking system components.

Construction and key technical features

GEN2 type spacers are manufactured as hubcentric components, which ensures proper seating of the wheel on the hub and maintains the alignment of the wheel-hub system. This type of solution is particularly important in high-performance cars, where steering precision and even load distribution have a direct impact on comfort and driving safety.

The most important features of the product include:

• hubcentric design reducing radial and axial runout,
• compatibility with 5x112 wheels with a 66.6 mm center bore,
• increase in effective track width by 20 mm per side.

A spacer configured in this way allows for the installation of wheels with a different ET or greater width, while maintaining the correct geometry of the wheel seating relative to the hub.

Practical application and benefits of installation

Installing hubcentric spacers of this type is particularly beneficial in situations where:

• the stock or aftermarket wheel is too close to the shock absorber, brake caliper, or suspension components,
• you want to achieve a more aggressive body line without interfering with bodywork,
• you care about improving the vehicle's lateral stability during dynamic driving.

Properly selected spacers can positively influence the perceived stiffness of the running gear, as well as the precision of steering response. At the same time, the hubcentric construction helps maintain even load distribution on the hub and wheel, which is important when operating on low-profile tires.

Product condition and installation aspects

The offered set comes from the category of used items, which makes it an attractive cost-effective solution while maintaining the functionality required for daily use. Before installation, it is recommended to perform a standard check of the contact surfaces, clean the hub and wheel of corrosion and dirt, and apply the appropriate bolt tightening torque in accordance with the vehicle manufacturer's recommendations.

Due to the nature of a component that has a direct impact on driving safety, installation should be performed at a professional service center or by a person with experience in working with running gear. Properly installed hubcentric spacers ensure stable wheel seating and predictable vehicle behavior across the full speed range.

Configuration expansion and selection of other components

If you are planning a comprehensive repair or upgrade of the running gear in your Audi and need other items 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.

When selecting used components for premium cars, it is also worth reading the guide on the cost-effectiveness of purchasing original parts from dismantling, such as the article Used parts for Mercedes – original parts from dismantling, which discusses the practical aspects of operation and selection of components in the high-end car segment.
