The recommended 5×120 wheel spacers size depends on several factors, including the desired fitment, tire size, and suspension modifications. Generally, most experts recommend staying within the range of 10mm to 25mm (0.4 to 1 inch) for wheel spacers. This range provides enough clearance for wider tires while maintaining safe operation and handling characteristics. However, many enthusiasts opt for thicker 5×120 wheel spacers to achieve a more aggressive stance.
Popular 5×120 Wheel Spacers Sizes
When choosing 5×120 wheel spacers, size is a key factor. From racing track day to daily commuter comforts, there are many choices of wheel spacer fitment. Depending on the car’s year and model, your vehicle has a range of potential stock wheel spacer sizes, including 3mm, 5mm, 10mm, 12mm, 15mm, and 20mm all the way up to 50mm.
- 3mm to 10mm: Subtle changes. They are just enough for clearing big brake calipers or slightly altering the offset.
- 12mm to 25mm: Moderate aesthetic improvement. They provide a perfect flush stance for most sedans and SUVs. You can notice an obvious enhancement in the vehicle’s handling, particularly when cornering.
- 30mm to 50mm: More aggressive stance. They are usually used for pickup trucks and specialized wide-body applications. It’s vital to opt for a high-quality hub-centric set.
How to Choose the Best 5×120 Wheel Spacers Sizes?
Choosing the right spacer size depends on your driving style, your car’s modifications, and your goals. Here are a few tips to help you decide:
Tire Size:
If you have upgraded to larger tires, you may need a larger spacer to prevent rubbing. The simple way is to measure from the outermost part of the rims/tires to the fender line. If the value is about 15mm, then around 15mm 5×120 wheel spacers are safe and legal to use.
Wheel Adapter Needs:
Technically speaking, the minimum required thickness of a wheel adapter is about 1 inch (25mm). Yes, you can put 5×120 wheels on 5×112 vehicles (Mercedes-Benz cars, Audi cars, and more) with 5×120 to 5×112 wheel adapters. It is required to consider the wheel offset issues.
Desired Look:
For an aggressive stance, go for 25mm to 50mm spacers. For a more subtle appearance, stick the 5×120 wheel spacers within 10mm to 20mm.
If you need 10-20mm wheel spacers, BONOSS forged lightweight plus 5×120 wheel spacers are perfect for you. They are hollowed for an extra lightweight advantage. The hollowed hole is a proven design that is effectively reducing weight. The average weight of each BONOSS forged lightweight plus spacer is more than 30% lighter than the previous-gen product. Adding such a small lightweight component won’t noticeably reduce fuel consumption. They also don’t hurt the wheel bearings.
If you need 25-50mm wheel spacers, BONOSS forged active cooling 5×120 wheel spacers are more suitable. These spacers come with heat dissipation grooves. The heat dissipation grooves are craved behind the spacers. When rotating, those grooves allow the external cold air to flow continuously inside the wheel spacer. The air takes away the heat, so it achieves the purpose of actively dissipating heat for the braking system.
Wide-body Compatibility:
If you have a wide-body kit, you’ll likely have more flexibility in spacer size. However, if you keep the stock wheels, bigger spacers (1.5 to 2 inches) might be the best to achieve a nice powerful look and avoid tire rubbing issues.
Considering the strength needs, BONOSS forged active cooling 5×120 wheel spacers are the best option. They are made of forged 6061-T6/ 7075-T6 aluminum alloy. The tensile strength is up 572 MPa (AL7075-T6). To ensure a stable and firm wheel connection, BONOSS forged active cooling wheel spacers provide ISO grade 12.9 wheel bolts (tensile strength over 1220 MPa) and ISO grade 10 wheel nuts (proof load over 1,100 MPa). Even facing impacts, these wheel fasteners are not easy to break.
