The 5×115 wheel spacers are becoming popular by the day for aesthetic purposes and fitment issues. By pushing the wheels out, spacers allow you to install bigger tires and larger brakes with no rubbing issues. The wheels and tires are set apart even further, which in return improves traction and stability. This also boosts cornering performance.
A car with perfect handling gives satisfaction to the driver and makes the drive safe and enjoyable. Simply, 15-30mm is the best size range for 5×115 wheel spacers. If you would like a more accurate data, it is better to measure the wheel gap. In the post, we will answer what sizes 5×115 wheel spacers are the best and the top brands.

5×115 Wheel Spacers Size Before and After
Thickness:
- 3mm-10mm: A good option for those who just need a little bit of wheel clearance to fit bigger brake calipers. But they require longer wheel studs.
- 15mm-25mm: For stock wheel setups of most sedans and sports cars, 15mm to 25mm spacers provide a perfect flush wheel stance. This also improves the handling.
- 30mm-40mm: Popular among serious modification enthusiasts looking for that bold, aggressive look. These 5×115 wheel spacers allow for larger tires without rubbing.
- 45mm-50mm: Ideal for those who need the extra clearance to fit a wide-body kit. By spacing the wheels and tires out, 2-inch 5×115 wheel spacers offer more stability while cornering.
Bolt Pattern:
Wheel spacers are installed on the hub assembly and, in return, attach the wheels to them. In this case, the bolt pattern is an important factor. If you use 5×115 wheel spacers, make sure the vehicle bolt pattern and wheel bolt pattern are the same 5x115mm.

Who Makes the Best 5×115 Wheel Spacers?
When it comes to safe 5×115 wheel spacers, quality is everything. For example, before leaving the factory, BONOSS tech staff will do a series of inspections on the finished wheel spacers to check for any defects. They measure the individual aspects of the spacers to make sure that they meet the design specification. BONOSS offers several key advantages that make their spacers a top choice.
1. Useful Active Cooling Function
With the same price as most rim spacers, BONOSS forged active cooling 5×115 wheel spacers provide an active cooling function. Distributed in petal shape, these grooves allow the external cold air to flow continuously inside the wheel spacer when it rotates.
The air takes away the heat to actively dissipate heat for the brakes. Such BONOSS forged active cooling 5×115 wheel spacers improve the cooling efficiency to reduce brake thermal decay.
2. Aerospace-grade Aluminum Materials
All BONOSS forged active cooling 5×115 wheel spacers are made of forged 6061-T6 or 7075-T6 billet aluminum alloy. The tensile strength is up to 572 MPa and the yield strength is up to 503 MPa (AL7075-T6). High tensile strength gives it strong resistance to being pulled apart, making it resistant to bending and breaking.
3. Strong Fasteners for Zero Loosen
To safely secure the spacers, BONOSS provides ISO grade 12.9 wheel studs (tensile strength≥1,220 MPa) and ISO grade 10 wheel nuts (proof load≥1,110 MPa). They are meticulously coated with Dacromet. This type of coating gives neutral salt spray resistance exceeding 500 hours. They won’t loosen easily.
