The B-Class W247 spacers can push the wheels out suitably so that the wheels are flush with the fenders, the appearance of the vehicle can be fuller and more attractive. At the same time, the problem of wheel adapters and the clash between wheel and brakes can be solved. BONOSS has the world’s first active cooling technique, and the rotation of spacer makes the external cold airflow efficiently and continuously inside the spacer, while cold air flowing, the heat of the braking system is taken away, achieving the effect of active cooling, and improve braking efficiency and drive safer.
3. How does the active cooling technique of B-Class W247 spacers work? Why it is a breakthrough for traditional spacers?
The back of W247 spacers has specially petal shape grooves. Because the rotation of the spacer makes the external cold airflow efficiently and continuously inside the spacer, while cold air flowing, the heat of the braking system is taken away, thereby achieving the effect of active cooling, improving braking efficiency, and reducing overheating of brakes. This technique maintains the brakes at normal temperature to ensure wheel spacers’ safety and driving security. For a long time, the function of the wheel spacers for cars is single. As a professional spacer designer and manufacturer, BONOSS relies on years of experience and hard work to create the world’s first active cooling technique, diversifying spacers’ functions and increasing the value. On top of that, the production cost of the active cooling technique is almost the same as traditional spacers. So that customers scarcely need to pay extra for this. It is precisely having more functions, higher performance, and more friendly wheel spacers prices that have become the choice of many customers.

In some sense, the Mercedes Benz B-Class W247 wheel adapters also play the role of wheel spacers increasing the wheel track. Because wheel adapter can push the wheel outward too, and make the wheel flush with the fender. At the same time, it can also be used to solve the gap issue of brakes, tie rods, and other suspension parts. Compared with spacers, Mercedes Benz W247 wheel adapters can change the PCD and the center bore diameter so that you can install wheels with different data. In brief, installing wheel adapters make the vehicle obtain better turning performance, a smoother driving experience, and a fuller appearance. For more detail, please click Do you need wheel spacers or wheel adapters.
16. How to measure and determine the thickness of the W247 spacers?
Using a straight edge or metal rule, place the straight edge on the outermost part of the rims where the wheel comes closest to the fender. Then this distance is the thickness that can achieve the look that flushes or nearly flushes with the fender. But if the wheel spacers are too thin, rims or caliper will still have interference. On the opposite, the tires will hit the fenders. So, using suitable size spacers not only ensure safety but also avoid breaking local laws and regulations. At present, BONOSS B-Class W247 spacers have a thickness of 25mm-60mm for choosing. For more detail, please click How to Measure Wheel Spacers for My Vehicle.
