What are the pros and cons of BMW F30 wheel spacers? What exactly do F30 wheel spacers do? Here is the answer to this BMW 3 Series. When the offset of your stock or aftermarket wheels is insufficient, the F30 wheel spacers would make up the custom offset by pushing the wheels away from the vehicle hub. Having your wheel brought out the ideal distance allows for mounting big brake kits without rubbing the suspension components. Many F30 3 Series owners often install spacers to achieve more stability especially while cornering the vehicle and a more aggressive stance. Your BMW 3 Series becomes more stable, this is effective when the vehicle is driven in bad weather. (Thanks to the owner for providing these pics)

How to choose BMW F30 wheel spacers? Installing BMW F30 wheel spacers offers many benefits to your vehicle. There are usually two types of wheel spacers: One type simply slides into the hub and come with their own lug studs and nuts, they are named “bolt-on wheel spacers”, while the other type bolts to the vehicle hub with another set of extended wheel bolts, they are called “slip-on wheel spacers”. European cars usually use wheel lug bolts to secure the wheels to the hubs. In this case, slip-on style BMW F30 wheel spacers 5×120 will be your most suitable choice. To ensure a proper installation, you will also need to use new extended wheel bolts which are longer than the stock ones by the thickness of your F30 spacers.
