11. What wheel spacers do I need fit for “HRE/WORK/BBS…” wheel rims on my BMW G29 Z4?
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.

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.

14. Can BONOSS wheel spacers solve the offset problems for install other vehicles’ wheels on BMW G29 Z4, 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 G29 Z4 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.
