The best Audi A4 B9 wheel spacers provide a perfect flush stance and keep your car from rubbing issues. Whether you are upsizing your wheels, installing bigger brake calipers, or simply widening car’s track, these wheel spacers turn out to be the most cost-effective way to solve fitment issues.

If you install them properly, high-quality Audi A4 B9 wheel spacers are exactly safe for daily driving and racing events. But with so many options out there, how do you know which sizes and types are the best option? Let’s dive into the world of wheel spacers and find out what works best for your wheel fitment.

Best Audi A4 B9 Wheel Spacers: Choose the Right Size

The thickness of Audi A4 B9 wheel spacers depends mostly on the car’s models, your personal preferences, and desired modifications. Here are the pros and cons of each size:

  • 3mm to 10mm: If you want to fit a big brake kit without significantly altering the wheel offset, then 3mm to 10mm spacers are the best option.
  • 12mm to 20mm: If you would like a perfect flush wheel stance, 12mm to 20mm spacers are more suitable. They enhance the handling, particularly when cornering.
  • 25mm to 50mm: If you like a more aggressive stance, you can use 25mm to 50mm wheel spacers with a wide-body kit. They help reduce body roll, which in turn leads to more comfortable driving.

Best Audi A4 B9 Wheel Spacers vs Offset Rims

The wheel spacers and offset rims are two popular solutions to change your car’s wheel stance. But which is better for your Audi A4 B9? Here are the pros and cons of them:

  • Flexible Offset:
    The offset of a wheel is fixed. If you want to alter the offset, you have to change the entire rims. However, Audi A4 B9 wheel spacers can alter the offset flexibly with the stock wheels.
  • Budget Friendly:
    Wheel spacers provide the same effect as many low-offset wheels, but the price is much lower than offset rims. You can use the savings to buy other upgrading parts.
  • OEM-like Stance:
    The best Audi A4 B9 wheel spacers allow you to achieve a perfect flush wheel style while preserving the OEM wheels.
