The best BMW E46 spacers are forged aluminum alloy wheel spacers. The forging process provides uniformity in the structure and composition of the finished part. It means these forged BMW E46 wheel spacers can withstand more external impact and shear strength without breaking. They are a much safer option. In short, forged E46 spacers have a longer and more reliable service life than castings. Always get rid of casting spacers. They may be cheaper, however, the saved money doesn’t worth it.
Truly, vehicle-specific BMW E46 spacers are considered to be safer than those universal types. They are machined to your vehicle specification, which ensures perfect fitment. A vehicle-specific spacer is often hub-centric. Hub-centric E46 M3 wheel spacers are machined to fit the specific vehicle hub. For example, the 5×120 spacers are made to fit exactly the BMW E46 M3 that runs the 5×120 bolt pattern. The center bore is designed to be 72.5mm which is the diameter of the hub flange where the wheel seats to the hub.
What Size BMW E46 Spacers Are Best?
Some people want to bring the wheel out by just 5mm, or some people would like 50mm spacers to fit a wide-body kit. As a general rule of thumb, it’s safe to fit BMW E46 spacers up to 20 millimeters. The actual width of the spacer will vary depending on the fenders gap. For instance, if the fender clearance is 20mm, then it is recommended to use E46 20mm spacers. By pushing the wheels more toward the edge, the BMW E46 spacers can easily offer an improvement in wheel area at a relatively low cost.
The best BONOSS BMW E46 spacers 3mm to 70mm are in stock and ready to ship. In addition, BONOSS manufactures a huge range of custom wheel spacers to fit a massive variety of different wheels and applications. Designed by professional mechanical engineers, these are made in an independent factory to the highest quality and are fully SGS & TUV tests approved. All BONOSS custom BMW E46 spacers are super forging and machined down precisely using an advanced CNC machine.
Can BMW E46 Spacers Crack?
When installed, BMW E46 spacers become the important parts that connect the wheels and hub assembly. When the spacer is exposed to weather elements and chemicals, rust occurs. Oxygen and water can easily corrode the spacer which accelerates the wear and tear of the vehicle’s wheel. Therefore, choosing BMW E46 spacers with great corrosion resistance is another way to add insurance to safety.
Proper anodizing greatly enhances the anti-rust ability. BONOSS BMW E46 spacers apply an excellent black hard anodizing process. This process provides the surface with better abrasion resistance, flame resistance, and smoother and harder finish protection than regular anodizing plating. The black dye not only brings a premium appearance but also tends to be lightfast. To be lightfast means that the colors will not fade as quickly. It is an ideal hard coating process for forged aluminum BMW E46 spacers.
