“She looks better,” after installing these 12mm Mercedes wheel spacers, the car owner said, “Simple but effective upgrades!” Wheel spacers bring your rims and tires outwards so that they can flush with the fender flares, giving your vehicle an excellent look. Through this function, they can create ideal space for solving the clearance issues of bigger brake calipers and suspension clearance issues after mounting bigger wheels and tires. In addition, they increase the distance between the left wheels and the right wheels, hence increasing the traction. With the improvement of the traction, your GLE W166 becomes more stable and the comfort level of handling improves a lot. They are also commonly used for improving overall beauty.
