As long as you use high-quality BMW M3 wheel spacers and install them properly, they are safe. Take the BMW M3 5×120 wheel spacers as an example, we use forged AL6061-T6 material (tensile strength ≥310Mpa), modern CNC machining by 0.02mm tolerance. All of our products have got more than 50 SGS TUV authoritative test reports. Compared with those cheap casting wheel spacers, BONOSS forged Lightweight Plus wheel spacers are safer, higher performance, and more professional in design. We believe more professional production offers more value for customers. For details, please check Are Wheel Spacers Good or Bad.

3. Will BONOSS BMW M3 wheel spacers cause vibration?

In fact, the wheel spacers just increase the track of the left and right wheels. When the wheelbase increases, the grip will also increase. BONOSS BMW M3 wheel spacers are designed to make a snug connection between the wheel and vehicle hub, reducing high-speed vibration and ensuring safer driving. Compared with ordinary hub centric wheel spacers, BONOSS uses the multi-stage hub centric design and precision 0.02mm CNC machining, which effectively guarantees the safety and reliability of the wheel spacers’ quality and provides higher stability. The multi-stage hub-centric can make the spacers more closely fitted to the wheel hub, greatly reduce the vibration of high-speed caused by the inaccurate hub centric, For details, please check Why do You Need Wheel Spacers with Hub Centric Rings.

4. What are the benefits of the “Lightweight Plus” design of BONOSS forged Lightweight Plus wheel spacers?

The “Lightweight Plus” of wheel spacers means that the hollow design is further optimized on the basis of the traditional wheel spacers. It is an effective design that can effectively reduce weight and energy consumption, improves handling while ensuring safety and reliability.

That means improving the performance, strength, and durability of the BMW M3 wheel spacers. BONOSS aims to provide wheel spacers with more additional functions, safer, higher performance, more professional design, and better installing experience, that is why we insist on independent manufacturing and continuous optimization of the design. For details, please check Are Wheel Spacers A Good Idea.

10. How do BMW M3 wheel spacers affect handling?

Installing wheel spacers is a cost-effective way to increase the wheel track by pushing your wheels away from the hub. A wider track means better traction, allows you more stable turning, improving the handling of your vehicle, even driving in bad weather, it won’t lose its grip. Moreover, most track racing cars will use every millimeter of wheel space available in their design for the highest performance and the best exteriors. With BMW M3 wheel spacers on, you can fill the gap in your fenders and get a more aggressive and powerful look. Meanwhile, BONOSS forged Lightweight Plus wheel spacers are accurate to 0.02mm, a more perfect fit to the wheel hub, which means that high-speed vibration is reduced, and offers a smoother driving experience. For details, please check Wheel Spacer Handling Improvement.

11. What wheel spacers do I need fit for “HRE/WORK/BBS…” wheel rims on my BMW M3?

An excessive positive offset will cause the inner edge of your rims and tires to rub against the suspension components. In this case, wheel spacers can create the clearance needed to avoid friction and correct the offset by pushing away from the vehicle hub. They can also be used to change the bolt pattern and center bore diameter of your car. In this way, modified rims with different data can be installed correctly. For example, BBS wheel rims, HRE wheel rims, WORK wheel rims, OZ wheel rims, etc. BONOSS has thousands of successful cases of manufacturing spacers for aftermarket wheel rims issues. Compared to those cheap casting spacers, BONOSS forged high-grade wheel spacers are safer and more professional. For details, please check When to Use Wheel Spacers for Aftermarket Wheels.

12. Can BMW M3 wheel spacers clear the clearance problem after replacing the “BREMBO/AP…” brakes?

Higher-performance brake kits are often bigger than the stock parts. A wheel spacer provides the space needed for larger calipers that cannot fit in the factory wheel space. By pushing out the wheels, you can get a larger ideal gap of the brake caliper without having to rub it when installing the wheel. These items function as Brembo wheel spacers, EBC wheel spacers, AP racing wheel spacers, Endless wheel spacers, etc. And for safety and quality, purchasing from a professional manufacturer is trustable. BONOSS has thousands of successful cases of manufacturing spacers for big brakes issues. Compared to other cheap casting wheel spacers, BONOSS forged Lightweight Plus wheel spacers are safer and more professional. For details, please check When to Use Wheel Spacers for Big Brake Kit.

13. What do wheel spacers do for wide-body kits/aero kits?

The wide-body enclosure usually includes large brake calipers and large wheel hub modifications. Wheel spacers allow you to install larger wheels and larger brakes which is a great safety upgrade especially if you plan to take your widebody car onto a track. Installing wheel spacers on BMW M3 is one of the easiest and most cost-effective options to get low and wide as well as to get flush the fender flares. Properly filled wheel arches can really make your widebody builds look wonderful. These items function as Mansory widebody kits wheel spacers, Brabus widebody kits wheel spacers, Liberty Walk widebody kits, etc. BONOSS offers 3mm-20mm thickness wheel spacers to meet your needs. BONOSS insists on manufacturing safer and more professional wheel spacers, which is a good choice for your excellent widebody kits. For details, please check When to Use Wheel Spacers for Wide-body Kit.

14. Can BONOSS wheel spacers solve the offset problems for install other vehicles’ wheels on BMW M3, such as “Mercedes Benz, Porsche…”?

In a sense, a wheel adapter is also a wheel spacer. Wheel spacers are used for clearance problems with brakes, tie rods, and other suspension components, to push the wheels outward and make the wheels more flush with the fender. Wheel adapters do all the same things as wheel spacers do. However, wheel adapters can change the bolt pattern and center bore diameter to allow you to bolt up wheels that are not made for your car. Installing wheel spacers can help you perfectly solve the problem of the wheels. To have better turning performance, smoother driving experience, and fuller appearance. For details, please check Do you need wheel spacers or wheel adapters.

15. How thick BMW M3 wheel spacers do I need?

Here is a simple method: use a straight edge such as a metal ruler, place the straight edge on the outermost part of the rims where the wheel comes closest to the fender (preferably the top), then, measure from the outside wheel to the straight edge. This distance is the size spacer you will need to achieve the look that flushes or nearly flushes with the fender line. Too thin, you will still have wheel/caliper interference. Too thick, and your tires will hit the fenders. Use proper size of spacers not only ensure safety but also avoid breaking your local laws and regulations. Currently, BONOSS provides 3mm-20mm thickness wheel spacers to meet your needs. For more information, please check How to Measure Wheel Spacers for My Vehicle.
