Getting the wheels widened with wheel spacers is a common practice that most drivers will do. Spacers are safe for daily driving and most race cars will 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. By choosing the correct wheel spacers, you will do more with less.

How thick wheel spacers can you add really depends on your wheel gap. 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.

Are OEM Custom Wheel Spacers Good?

As a matter of fact, custom-made wheel spacers are not that expensive if you care about the quality and performance. Normally, manufacturers will mass production wheel spacers that fit most of the popular vehicle models. The thickness range from 3mm to 70mm, which provides various options. But once none of them meet your needs, custom spacers will be a good idea. They are specially fabricated for the rims.

To ensure safety and perfect fitment, you must have the hub-centric rings milled into the spacers. Please don’t think a polycarbonate ring does the job, it never does. Next are the wheel lugs. You have to make sure they are strong enough. Because they play a critical part in keeping the spacers and wheels in place. Only high-strength wheel fasteners can withstand forces without breaking in the long term.

How Are Custom Wheel Spacers Made?

Custom wheel spacers are meant to fit your specific functions or requirements. After confirming the thickness, bolt pattern, thread, material, and other details, we have a professional team involved in the whole process. From designing to producing, the process is based on your unique specifications. At the BONOSS factory, custom wheel spacers from 3mm to 160mm are available and the dimension can range from 130mm to 350mm.

All BONOSS custom wheel spacers are forged, which assure basic strength, toughness, and structural integrity. Forged 6061-T6 aluminum and 7075-T6 aluminum are two of the most popular materials that are used to make high-end spacers. All spacers are precision turned with high-precision and cutting-edge CNC machines to ensure 0.02mm tolerance. They will undergo thoroughly a series of performance tests to ensure they can handle our scrutinous standards before leaving the factory.
