Are wheel spacers good or bad? This is not the main question, the main determining factor that decides the wheel spacers’ pros and cons are their quality, fitting, and installation. If you purchase low-quality spacers and install them improperly for a vehicle, a serious problem will arise while driving. Spacers have existed for multiple decades, and as long as they are high quality and installed correctly, there is very little opportunity for failure. They have always been used widely, even within the highest level of racing events. People tend to be sensationalized on the internet, especially because they don’t want to admit that they have made mistakes in tightening the lug nuts or purchased cheap low-quality spacers. Therefore, properly installed high-quality wheel spacers are perfectly safe.
