Are Wheel Spacers Safe for My Renault Laguna? Wheel spacers have existed for multiple decades, and there is very little opportunity for wheel spacers failure. They have always been used widely, even within the highest level of racing events. As long as you use high-quality Renault spacers and install them properly, they are just as safe as normal wheel changing. Just as your wheels, tires, and brake mods, only good products can ensure driving safety. The quality and safety often depend on the design, materials, performance, and manufacturing process. BONOSS wheel spacers are designed with actual measurement, using forged AL6061-T6 material (tensile strength ≥ 310Mpa), high strength for bearing most impacts.
