Do these Mercedes A45S wheel spacers affect the turning radius? Installing A45S wheel spacers helps increase the distance between the left wheels and the right wheels, hence increasing the track of the car. This will increase the turning radius a little but it also adds stability. In addition, the resistance to rollover enhances when the wheels of the vehicle are moved outwards from the OEM wheel assembly. The grip of the vehicle is also strengthened when the wheel track increases. As a result, when your A45S moves in rough weather or unfavorable driving conditions even then, it does not lose its grip on the road. With the improvement of the traction, the comfort level of handling the vehicle improves a lot. The Mercedes A45S wheel spacers assist vehicle owners in making custom wheel adjustments. On the other hand, if wheel spacers are not installed, it may result in inappropriate adjustments to the components of your Mercedes-Benz A45S.
