Getting the wheels widened with 20mm wheel spacers is a common practice that most drivers will do. Spacers are safe for daily driving and most race cars also use them. It is a cost-effective way to increase track width, hence improving the stability and rollover resistance. The wheels on the same axle are further apart, which contributes to better handling when turning.

For most sedans and SUVs, it is recommended to stick to the rule of thumb of running wheel spacers not passing through the fender flares. Place a straight edge flush with the outermost wheel edge. Then measure from the wheel edge to the inner fender lip. If the result is 20mm, then 20mm wheel spacers are fine.

Pro Tips to Install 20mm Wheel Spacers Safely

There are several critical tips that may help you get proper installation:

  1. Spray degreaser on the studs and use a wire brush to clean the threads. This allows the lug nuts to fasten well.
  2. If the hub is dirty, rusted, or pitted use the emery cloth to clean up the surface. Wipe down the entire hub surface, ensuring it is clean and smooth. This needs to be done thoroughly.
  3. Test if the spacer fits your vehicle hub. Ensure that the spacer is firmly seated and flush against the hub.
  4. Tighten the lug nuts with a torque wrench in a star pattern. This should be done to the manufacturer-recommended torque.
  5. Double-check that all lug nuts are tightened to the manufacturer’s specification with a properly calibrated torque wrench in a crisscross, star pattern.

What Are the Best 20mm Wheel Spacers?

Safety, precision, strength, and best experience are what sets BONOSS apart from other spacers manufacturers. All BONOSS forged active cooling 20mm wheel spacers are built strictly to operate well in heavy-duty. BONOSS offers several key advantages that make their spacers a top choice.

1. Active Cooling for Better Braking Performance

To further improve the heat dissipating ability, BONOSS forged active cooling 20mm wheel spacers come with petal-shaped cooling grooves. These grooves allow the external cold air to flow continuously inside the wheel spacer when it rotates. The air takes away the heat, so these BONOSS forged active cooling 20mm wheel spacers can actively dissipate heat for the braking system.

2. Forged Aluminum for Improved Safety

If you are looking for wheel spacers with durability and lightweight, then buying aluminum wheel spacers is the route to go. After a super forging process, the tensile strength of BONOSS forged 7075-T6 aluminum wheel spacers is up to 572 MPa. The higher the tensile strength, the more tensile stress that the wheel spacers can withstand before failure.

3. Full-cone Seat for Enhanced Stability

When it comes to bolt-on spacers, there are lug holes. BONOSS forged active cooling 20mm wheel spacers come with precise full-cone lug seats. The full-cone shape allow the wheel nuts to fully contact the spacers, providing a stronger and more secure fit. This is effective to avoid any potential loosening risks.
