Ultimate review of Audi A4 wheel spacers: before and after

Audi A4 wheel spacers are aluminum alloy rings that fit between the hub and the wheel, creating extra clearance and pushing the wheels outwards. They can improve the appearance, handling, and performance of your Audi A4. In this ultimate review, we will look at the benefits of Audi A4 wheel spacers and tips of selecting and installing them.

What are the benefits of Audi A4 wheel spacers?

Enhancing the stance and aesthetics. Wheel spacers can make your wheels look more flush with the fenders, giving your car a more aggressive and sporty look. They can also allow you to fit larger or wider wheels and tires that would otherwise rub against the suspension or the body.

Increasing stability and cornering. Wheel spacers can widen the track width of your car, which means the distance between the left and right wheels. This can improve the balance and grip of your car, especially when turning or cornering at high speeds. Wheel spacers can also reduce body roll and understeer, making your car more responsive and fun to drive.

Correcting the offset and bolt pattern. Wheel spacers can help you adjust the offset of your wheels, which is the distance between the centerline of the wheel and the mounting surface on the hub. If your wheels have a less than ideal offset, they can cause steering issues or interfere with other components. Wheel spacers can also help you fit wheels with a different bolt pattern than your hub if you modify to larger wheels, which can expand your options for aftermarket wheels.

How to choose and install Audi A4 wheel spacers?

The stigma around the safety of wheel spaces continues to remain in question due to the low quality and improper installation. Opting for quality and fitment of spacers and installing them correctly is vital to boost your vehicle while retaining safety as stock.

The size and thickness of the spacers. The size and thickness of the spacers will determine how much they will push out your wheels and how they will affect your offset and clearance. You need to measure the gap between your wheel and fender, as well as the backspacing of your wheel, to find out how much space you have to work with. You also need to check if your wheels have enough studs or bolts to accommodate the spacers safely. The bolt pattern of Audi A4 is 5×112, the hub bore diameter is 66.5 (2008-2023). A reference thickness combination is front 10mm, rear 15mm.

The quality and material of the spacers. The quality and material of the spacers will affect their durability and performance. You should look for spacers that are made of high-strength materials, such as aluminum or steel, that can withstand high pressure and temperature. You should also look for spacers that are hub-centric, meaning they match the center bore of your hub and wheel, to ensure a proper fit and balance.

The installation process and tools. The installation process and tools will vary depending on the type and size of the spacers you use. Some spacers are bolt-on, meaning they attach to your existing studs or bolts with nuts or lug nuts. Others are slip-on, meaning they slide over your existing studs or bolts with longer ones. You will need a jack, jack stands, a torque wrench, a socket set, and a breaker bar to install the spacers safely and correctly. You will also need to check the torque specifications and the clearance of your wheels after installing the spacers.

This material is the first-rate aluminum alloy utilized in spacers, showing high strength as steel while far lighter and not prone to rusting. All these spacers have been covered by a black anodized coating. After anodic oxidation treatment, an oxide film of several microns to hundreds of microns can be formed on the surface of aluminum, which can improve the wear resistance, corrosion resistance and weather corrosion resistance of spacers.

Active cooling grooves. Most vehicles face the issues of thermal decay after a long and high-speed driving journey. The brake response hence is delayed and affects your driving quality. In the surface of BONOSS Audi A4 wheel spacers, five curved grooves are engraved in light of aerodynamics to create space that allows air to flow and dissipate heat generated by the brake. This design has been proven to contribute to heat dissipation and brake response improvement.

Easy to dismount. If you live in an area that sees snow or salt, spacers are prone to getting stuck due to mineral deposits and salt mixing with moisture. The dismounting grooves in the corner of BONOSS Audi A4 wheel spacers save you from this trouble. You can utilize a screwdriver to remove the spacers easily.
