Wheel spacers suggest!

Welcome to the forums @sunnyxu. I have used wheel spacers on 4x4's but not on a road car. Not sure of the need for them on most EC models. If you have a lower end spec EC with narrow/smaller wheels they may be of benefit but in Australia we have wheels which fit to the edge of the wheel well and adding spacers would make the car illegal as the wheels would protrude past the cars outside edge. Lastly, I have read feedback from users on Reddit that warn that BONOSS spacers can be quite brittle and are prone to cracking. I suggest doing some research on available spacers first.
