BONOSS Forged Lightweight Plus Wheel Spacers 12mm+12mm for Mercedes-Benz A45S (1)

What does a Mercedes A45S wheel spacer do? Here is an answer from the owner of this Mercedes-Benz A45S – for appearance and performance enhancement. Wheel spacers bring your rims and tires outwards so that they can flush with the fender line, giving your A45S an excellent stance. Many car manufacturers will leave a certain amount of fender space for tire chains. And most track racing cars would make use of every millimeter of the wheel arches space available in their design for the highest performance and the best exteriors. A wider wheel track means better traction, hence increasing body control experience. With spacers, you can fill the gap in your fenders and get a more aggressive look! (Thanks to the owner for supporting.)

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.

How Thick Mercedes-Benz A45S Wheel Spacers Do I Need?

Pushing the wheels outwards to an ideal position increases the distance between the left and right wheels. A wider wheel track offers better traction, leading to more stability and better handling performance for your Mercedes-Benz A45S. We recommend you do the necessary groundwork to measure and determine what size you will ultimately need as every vehicle are different and may require different sized spacers. The normal method is that: use a straight edge such as a metal ruler, place the straight edge on the outermost part of the rims where the wheel comes closest to the fender (preferably the top), then, measure from the outside wheel to the straight edge. This distance is the size A45S spacer you will need to achieve the look that flushes or nearly flushes with the fender. Too thin, you will still have wheel/caliper interference. Too thick, and your tires will hit the fenders. For this Mercedes-Benz A45S A45S, front/rear 12mm(≈1/2″) is perfect fitting.

How to Install A45S Wheel Spacers Safely?

The A45S wheel spacers need to be installed correctly, and they also must be properly torqued to manufacturer-recommended torque specs. This means making sure the spacer, wheel, and hub are secured enough to where they don’t get loosen. Untightened lug bolts (the clamping force is not enough) or overtightened lug bolts (the wheel bolt has been stretched past its tensile strength limit, so the clamping force has gone away) will cause most lug bolt failures. Find a suitable balance in the level of tightness and the wheel bolt will remain strong, providing the greatest possible force to lock the wheel to the hub. This ensures the wheel spacers safe.
