Hub-Centric Rings with a 56.1mm Inside Diameter

Improve aftermarket wheel fitment with hub-centric rings designed for vehicles with a 56.1mm hub diameter. These precision-sized wheel-centering rings fill the space between the vehicle’s hub pilot and the larger center bore of a compatible aftermarket wheel.

Using the correct hub ring helps position the wheel concentrically on the hub during installation. This can make mounting easier and help reduce vibration associated with an aftermarket wheel being installed off-center.

The 56.1mm hub diameter is commonly found on many Subaru applications. However, the vehicle make and model alone cannot confirm fitment. You must also choose an outside diameter that precisely matches the center bore of your aftermarket wheels.

Choosing the Correct 56.1mm Hub Ring

Every hub-centric ring has two essential measurements:

• Inside diameter: Fits over the vehicle hub. Every ring in this collection has a 56.1mm inside diameter.
• Outside diameter: Fits inside the aftermarket wheel’s center bore.

For example, a 72.6mm-to-56.1mm hub ring fits an aftermarket wheel with a 72.6mm center bore and a vehicle with a 56.1mm hub diameter.

Common outside-diameter options may include:

• 60.1mm to 56.1mm
• 66.1mm to 56.1mm
• 67.1mm to 56.1mm
• 70.3mm to 56.1mm
• 72.6mm to 56.1mm
• 73.1mm to 56.1mm
• 74.1mm to 56.1mm
• 82.8mm to 56.1mm

Available sizes and materials may vary. Plastic hub rings are suitable for normal street applications, while available aluminum hub rings may be preferred for applications exposed to higher brake temperatures.

Benefits of Hub-Centric Rings

• Help center aftermarket wheels on the vehicle hub
• Help reduce vibration associated with off-center installation
• Fill the gap between the wheel center bore and hub pilot
• Make wheel positioning easier during installation
• Available for numerous aftermarket wheel-bore sizes
• Offered in plastic and aluminum configurations
• Typically sold in sets of four for a complete vehicle

Plastic or Aluminum Hub Rings?

Plastic Hub-Centric Rings

Plastic rings are lightweight, corrosion-resistant and suitable for most daily-driven street vehicles. They provide a practical solution for wheels and brakes used under normal operating conditions.

Aluminum Hub-Centric Rings

Aluminum rings offer durable metal construction and may be preferred for performance applications or vehicles exposed to higher brake temperatures. Periodic inspection and appropriate maintenance can help prevent corrosion from making metal rings difficult to remove.

Important Fitment Information

A vehicle compatibility tool may help confirm that your vehicle has a 56.1mm hub, but it cannot determine the center-bore diameter of an aftermarket wheel. Consult the wheel manufacturer’s specifications or carefully measure the center bore before ordering.

Both measurements must match:

1. The ring’s 56.1mm inside diameter must match the vehicle hub.
2. The ring’s outside diameter must match the aftermarket wheel bore.

Not every Subaru uses a 56.1mm hub, so verify the exact hub measurement for your year, make and model. Hub-centric rings also do not change a wheel’s bolt pattern, offset, load rating, lug-seat design or brake clearance.
