Installing BMW 12mm wheel spacers provides many benefits to your vehicle, such as a more sporty exterior, better steering experience, clearing suspension clearance issues, and better ability to roll over obstacles. Is using BMW wheel spacers safe? We’ve seen them work successfully on race cars countless times, as long as you use high-quality BMW spacers and install them properly, installing wheel spacers is exactly safe. Never skimp on price and end up with unsafe low-quality spacers. The quality is always a huge deal when it comes to the components you add to your BMW 7 Series. In the market, wheel spacers made from aircraft-grade billet aluminum are the basis of quality spacers.

Will 5×112 12mm Wheel Spacers Cause Vibration?

As a matter of fact, BMW spacers in themselves don’t cause vibration, they simply serve as an extension of the original wheel hub surface. The vehicle’s wheels are actually fastened to the corresponding wheel hub by a clamping force achieved by tightening the wheel bolts of each wheel. This allows all forces to be transmitted through each vehicle’s hub and its corresponding axle. Therefore, the weight of your BMW G12 7 Series will not be placed on any wheel spacers that are installed. Get rid of the lug-centric wheel spacers and make sure everything was mating up correctly.


Installing hubcentric BMW 5×112 wheel spacers is a good option to make your car stand out and improve the ride and performance. Without hub-centric spacers, the wheel cannot be centered on the axle, leading to annoying wheel vibrations while driving. Although it is possible to center the lug-centric wheels by proper installation technique, the wheel will be off-center without hubcentric spacers. BONOSS has offered quality BMW hubcentric wheel spacers for over 10 years. Compared with traditional hub-centric spacers, we have upgraded the universal design, which is called “multi-stage hubcentric”. BONOSS multi-stage hubcentric wheel spacers fit your existing wheel hub perfectly, further reducing the chance of high-speed vibration.

When Do You Need BMW Extended Wheel Bolts?

It is critical to ensure your BMW wheel bolts are long enough for the proper thread engagement. At the minimum, thread engagement length must be equal to or greater than the diameter of the fastener. In other words, if the stock bolt is 14mm in diameter, there must be at least 14mm thread. If not, you’ll either need to change to thinner BMW spacers or get longer and stronger wheel bolts installed. Giving an example, the stock G12 bolt’s length is 27mm, and you have installed 12mm wheel spacers, then 39mm wheel bolts will be required. But if you upgraded to aftermarket wheels, then you need to make sure the seat type will fit properly.
