Tire specialists consider hub-centric wheel spacers are the best spacers for E90. Because almost all OEM wheels are hub-centric and this can create a firm and stable wheel connection. It is this contact point that bears the weight of the vehicle. The wheel bolts are designed to secure the wheels with a clamping force and resist lateral forces that are experienced when the vehicle is cornering. They are not designed to carry the weight of the vehicle. So, hub-centric BMW E90 wheel spacers are eventually the best spacers to ensure safety.
When it comes to the best BMW E90 wheel spacers, always choose the genuine brand set. Indeed, reputable manufacturers make nice wheel spacers. A genuine brand typically becomes a genuine brand because it has developed a reputation for high quality. The manufacturing process is strictly regulated, and factories only use processes that have been proven to be safe. Using such BMW E90 wheel spacers, you will be worry-free in any condition.
Are Forged Aluminum BMW E90 Spacers Good?
Typically, the best BMW E90 wheel spacers are made of aluminum alloys. But even if the material is the same, different manufacturing process provides different mechanical performance. Forged BMW E90 wheel spacers are often more durable. They are significantly stronger and tougher than casting aftermarket spacers. In the forging process, tons of continuous stress make the internal structure more compact, adding strength to combat everyday wear and tear.
Simply put, when facing bump and impact loads, higher tensile strength can bear greater forces without breaking. BONOSS forged BMW E90 wheel spacers perform better: the tensile strength is up to 572 MPa, and yield strength is up to 503 MPa (AL7075-T6). The unique super forging process makes these spacers more durable and more resistant to corrosion and oxidation. So, these BONOSS forged BMW E90 wheel spacers feature inherent strength and durability against whatever you can throw at them during a lifetime of driving.
What Are Rustproof BMW E90 Wheel Spacers?
Basically, aluminum alloys are good in corrosion resistance and rust-proof. When aluminum contacts the air, it forms a layer of oxide which renders it non-reactive with elements that are corrosive to the underlying metal. BMW E90 wheel spacers made of aluminum alloys are no different. They are resistant to rust and corrosion, unlike their steel counterparts.
To further improve the corrosion resistance and appearance of the spacers, BONOSS aluminum BMW E90 wheel spacers are excellent candidates for black hard coat anodizing. A proper hard anodizing coating ensures complete protection against corrosion. The oxide layer that follows the anodizing process offers excellent protection. The black dye not only brings a premium appearance but also tends to be lightfast. This means anodizing aluminum BMW E90 wheel spacers are not easy to corrode or oxidate which makes them safely work for long-term use.
