BONOSS-Forged-Lightweight-Plus-Wheel-Spacers(formerly-bloxsport)-for-Mercedes-GlE-12mm-15mm-(6)The wheel spacer or adapter is sandwiched between the car’s wheel and hub. By pushing the wheel away an ideal distance from the hub, it creates spaces between the wheel and hub. If your new wheels set up do not have the proper offset, it will cause the wheel to rub against the internal suspension components. (Wheels will stick in too much). If you have upgraded your braking system with bigger calipers, it will take up spaces which cause the wheel cannot be mounted back properly. Installing wheel spacers or adapters can create extra clearance to push the wheels outward to correct the wrong offset as well as pass larger calipers for wheel fitment. They are also commonly used for handling improvement and visual enhancement. By spacing the wheels out, it will provide more stability and better corner control to the vehicle. Furthermore, properly filled the wheel arches can really make a car look excellent.
