Not all 2023 Audi RS4 wheel spacers are created equal, and choosing the right size for your car is crucial. If the spacers are too thin, they might not make a noticeable difference or even cause vibration issues. If the spacers are too thick, they might cause excessive stress on the wheel bearings, hubs, or studs, or interfere with the bodywork or suspension.

So how do you determine which size 2023 Audi RS4 wheel spacers should you get? There are several factors to consider, such as:

  • The original wheel size, PCD (pitch circle diameter), offset, and center bore of your car
  • The desired wheel size, PCD, offset, and the center bore of your aftermarket wheels (if applicable)
  • The amount of clearance or poke you want to achieve
  • The legal limits or regulations in your area regarding wheel spacers

The 2023 Audi RS4 has a wheel size of 19×9 inches, a PCD of 5×112 mm, an offset of ET26 mm, and a center bore of 66.6 mm. These specifications are important to know when choosing wheel spacers, as they determine how the wheel fits on the hub and how far it sticks out from the fender.

How thick 2023 Audi RS4 wheel spacers should you pump?

If you want to keep your original wheels, you can use a simple formula to calculate how much spacer thickness you need to achieve a certain amount of poke (the distance from the outer edge of the wheel to the fender):

Spacer thickness = Desired poke – (Wheel width / 2 + Offset)

For example, if you want to have a 5 mm poke, you can plug in the numbers:

Spacer thickness = 5 – (9 / 2 + 26)

Spacer thickness = -17.5 mm

This means that you don’t need any spacers at all, as your original wheels already have a slight poke of 17.5 mm. In fact, adding any spacers would make your wheels stick out too much and potentially cause problems.

However, if you want to install aftermarket wheels with different specifications, you need to adjust the formula accordingly. For example, if you want to install 20×10 inch wheels with a PCD of 5×112 mm, an offset of ET35 mm, and a center bore of 66.6 mm, and you still want to have a 5 mm poke, you can plug in the numbers:

Spacer thickness = 5 – (10 / 2 + 35)

Spacer thickness = -25 mm

This means that you need to install 25 mm thick spacers to achieve the same amount of poke as your original wheels. However, this might be too much for your car, as it would increase the track width by 50 mm and possibly cause rubbing or scraping issues. Therefore, you might want to opt for thinner spacers or lower your car’s ride height to accommodate the bigger wheels.
