The BMW X5 wheel spacers come in different sizes because of different requirements. When the wheels and tires are not ideal, the wheel spacers are the best solution. For most BMW cars, there is a difference in the track width between the front and the rear. If you change to new offset wheels, this will be more obvious. Anyway, some people prefer a flush look. In this case, you can put on different sizes of BMW X5 wheel spacers to bring the wheels a bit flusher with the fenders.
Most dealers sell BMW X5 wheel spacers in pairs. This is because the same two spacers keep the wheels looking equally spaced in the wheel wells. When you are changing the size of the wheels, the overall diameter of the tire and wheel assembly must remain the same to keep the proper settings. Therefore, if one front wheel needs a spacer, it would make sense that the other front wheel on the opposite side would also need it (assuming the rims and tires are the same).
Are BMW X5 Wheel Spacers Good or Bad?
If you plan to upgrade the wheel style, adding aluminum wheel spacers is a good idea. For example, BONOSS forged active cooling BMW X5 wheel spacers come with heat dissipation grooves to improve the brake cooling efficiency. Distributed in petal shape, these grooves allow the external cold air to flow continuously inside the wheel spacer when it rotates. The air takes away the heat, so it achieves the purpose of actively dissipating heat for the braking system.
There are small notches that are distributed on the corner of BMW X5 wheel spacers. These notches act as air collectors which tremendously enlarges the airflow, enhancing the heat dissipation effect, and improving road safety. In addition, these BMW X5 wheel spacers are machined with knurled sides. The knurling surfaces eliminate internal stress which contributes to more reliable product mechanical properties. This enlarges the cooling area which is good for the active cooling effect.
Are BMW X5 Wheel Spacers Safe at High Speeds?
As long as you stick to quality BMW X5 wheel spacers and install them correctly, they are exactly safe at high speeds. All BONOSS forged active cooling wheel spacers are made of 6061-T6 and 7075-T6 aluminum alloy. For racing, drift, and high-speed events, aluminum 7075-T6 wheel spacers are the best option. If you must consider the costs of the X5M spacers, 6061-T6 spacers are the perfect solution. BONOSS tests each spacer meticulously to make sure they give the biggest safety or reliability possible.
A good set of BMW X5 spacers is precisely made to fit your sports car. BONOSS forged active cooling wheel spacers are designed with better multi-stage hub-centric rings. The multi-layer design provides the bevels to fit the corresponding hub flange, which eliminates any possible gaps. These BONOSS multi-stage hub-centric BMW X5 spacers effectively ensure a firm wheel connection and better load transition. The wheels are well-balanced so that there will be less chance of vibrations.
