Putting BMW M4 wheel spacers on each wheel increases the track width. A wider track enables your tires to grip the road surface better, and the resistance to rollover enhances. Even if it is only a few millimeters, you will notice the difference right away. Besides, the BMW spacers create more inner wheel clearance to accommodate a big brake kit.

If you would like to achieve a flush stance, these BMW M4 wheel spacers are helpful. By moving the wheels out a few distance, they make your car look sporty and muscular. You can achieve such a purpose without replacing the stock wheels. To avoid costly mistakes, we’ll explore the best BMW M4 wheel spacers and the top brands.

What is the Best Offset for BMW M4 Wheel Spacers?

The BMW M4 wheel spacers can change the wheel offset. For example, a 12mm spacer will reduce about 12mm offset. If you have aftermarket wheels that don’t have the ideal offset, wheel spacers can help achieve the perfect fitment. This enlarges the options of wheel and tire combinations.

What is the BMW M4 Wheel Spacers Torque Spec?

The REFERENCE torque spec of the BMW M4 wheel spacers is 103.5 ft-lb (140 Nm). This is just a reference value. Some wheels or applications may require more or less tightening torque. It is always a good idea to ask a tire expert to figure out the exact torque spec before operating.

How Long Wheel Bolts Do I Need for BMW M4 Wheel Spacers?

In fact, extended wheel bolts are a MUST option for safely securing BMW wheel spacers. On this basis, if the OEM wheel bolt length is 27mm and you get a 15mm wheel spacer installed, it is recommended to use 42mm wheel bolts (stock bolt length + spacer thickness = required wheel bolt length).
