2. What are the benefits of installing BONOSS wheel spacers on Audi?
Wheel spacers provide many benefits to your Audi. For example, clearing suspension clearance issues after mounting bigger wheels and tires, better steering experience and more grip power, better ability to roll over obstacles. In addition, pushing your wheels out to a certain distance allows you to add a bigger brake kit without rubbing the wheel. BONOSS wheel spacers provide all the benefits above. In addition, BONOSS Audi spacers apply the Global Pioneer Active Cooling Technique which utilizes the rotation of the spacers to allow the external cold air to enter and continuously flowing inside the spacers, enhancing the heat dissipation of the braking system, reducing brake fade. The braking efficiency gets improvement, driving is safer.
3. How does the active cooling function works on my Audi?
As a professional Audi wheel spacers manufacturer, BONOSS created the Global Pioneer Active Cooling Technique, breaking the single functionality of the traditional wheel spacers. The special petal shape grooves utilize the rotation of the spacers to allow the external cold air to enter and continuously flowing inside the spacers, enhancing the heat dissipation of the braking system. Installing BONOSS active cooling wheel spacers helps improve the heat dissipation of the brake system, reducing brake fade while providing the functions of traditional spacers. The cost of manufacturing an active cooling wheel spacer is nearly equal to the traditional alternative. You don’t need to pay extra fees for the cost, that is why BONOSS offers better functions and higher performance wheel spacers, but maintaining a particularly friendly price.

5. Why your Audi need hubcentric wheel spacers?
Hub-centric wheel spacers pilot by the center bore of the vehicle hub. This means they center on the hub of the vehicle while simulating the piloting lip on the face side. Besides, according to the size of the hub centric lip, they transform lug centric wheels into hub centric wheels. Most vehicles need hubcentric wheel spacers to create a strong hub-spacer-wheel connection. Based on traditional hubcentric Audi spacers, BONOSS has optimized this design for further reducing the chance of high-speed vibration, it is called multi-stage hubcentric design. According to the actual test, the effect of BONOSS multi-stage hubcentric wheel spacers is far better than the common alternatives, which fit more perfectly, safer, and more stable. For more details, check on Why do You Need Wheel Spacers with Hub Centric Rings.
6. What are these Audi wheel spacers made of?
BONOSS manufactures Audi wheel spacers with aircraft-grade forged 7075-T6 billet aluminum alloy, which features many desirable properties such as high strength, wear-resistance, excellent toughness, impact resistance, and high-temperature resistance. This metal performs good mechanical properties: Tensile strength≥572Mpa, Yield strength≥503Mpa and Failure Elongation≈11%. Although, many stores claim that they are selling 7075-T6 aluminum spacers, but they are not made by the forged process. In fact, they are cheap casting spacers. Forging provides higher performance spacers than casting. It further enhances the hardness and toughness of the spacers. With the same material and cost, the strength and safety of forged spacers are far higher than casting ones. For more details, check on How to Choose Safe Wheel Spacers.
7. What’s the performance of the matching wheel bolts of Audi wheel spacers? What does “BONOSS Engraved” means?
The matching wheel bolts of BONOSS Audi spacers applied high-strength JIS SCM440 steel material. They have achieved ISO standard grade 12.9, tensile strength≥1,220Mpa, limited life range test≥2,000,000 stress cycles without damage, ultimate tensile load≥152,000N, hardness (HV)≥395, NSS≥500H. And the matching inset lug nuts have achieved ISO standard grade 10, proof load≥1110Mpa, hardness (HV)≥349, NSS≥500H. Many competitors often use other brands of bolts and nuts in pursuit of lowering the cost, and these bolts and lug nuts are often only marked with metric units without brand engraved. In view of this, each BONOSS matching wheel stud, as well as lug nut, is “BONOSS engraved”, meaning these matching wheel bolts are made by BONOSS’s own factory, the quality is guaranteed, customers’ interests are protected, and BONOSS takes the quality responsibility.

10. How does knurling design work on the Audi wheel spacers?
For decorative reasons, knurling can enhance the aesthetics of the Audi wheel spacers by introducing an attractive pattern to the side surface. In addition to aesthetics, there are practical features. Knurling patterns can enlarge the side area so that it can contact more air, boosting the heat dissipation effect, reducing internal stress and also reducing the weight of spacer. That means improving the performance, strength, and durability of the spacers. BONOSS aims to provide wheel spacers for Audi with more additional functions, safer, higher performance, more professional design, and better installing experience. BONOSS independent design department insists on professional manufacturing and continuous optimization of the design. For more details, check on Are Wheel Spacers A Good Idea.
11. How do Audi wheel spacers affect handling?
Wheel spacers bring your Audi rims and tires outwards, increasing the distance between the left wheel and the right wheel. And most track racing cars would make use of every millimeter of the wheel-wells space available in their design for the highest performance and the best exteriors. A wider wheel track means better traction, hence increasing body control experience, offering better corner performance, and more stable driving. With the Audi spacers, you can fill the gap in your Audi fenders and get a more aggressive and powerful look. Finishing with 0.02mm tolerance, BONOSS wheel spacers fit more perfectly to the wheel hub, which means reducing high-speed vibration, offering a smoother driving experience. For more details, check on Wheel Spacer Handling Improvement.
12. Why do you need Audi wheel spacers for aftermarket wheel rims?
Truly, hub-centric spacers are around as important for aftermarket wheels as lug bolts are. 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 desired clearance to correct the offset by pushing the wheels away from the vehicle hub. They can also be used to change the bolt pattern and center bore diameter of your Audi. These items function as BBS wheel spacers, Work wheel spacers, HRE wheel spacers, Rays wheel spacers, OZ wheel spacers, and Enkei wheel spacers at the same time. BONOSS has thousands of successful cases of manufacturing spacers for aftermarket wheel rims issues. For more details, check on When to Use Wheel Spacers for Aftermarket Wheels.
13. Can Audi wheel spacers clear big brake kit issues?
Higher-performance brake kits are often bigger than the stock parts. A wheel spacer makes required room for a larger caliper that wouldn’t fit in the factory wheel space. By pushing out the Audi wheel, you can gain the ideal amount of clearance for a bigger brake caliper instead of rubbing against it when mounting back the wheel. If you have upgraded your brake system with bigger brake calipers and need to fix the clearance issues, proper Audi wheel spacers will be your instant and cost-effective solution. These items function as Brembo wheel spacers, EBC wheel spacers, Wildwood wheel spacers, AP Racing wheel spacers, Endless wheel spacers, and Power Stop wheel spacers at the same time. And for safety and quality, purchasing from a professional manufacturer is trustable. For more details, check on When to Use Wheel Spacers for Big Brake Kit.

BONOSS offers a huge range of Audi wheel adapters to fit a massive variety of different vehicles. Common requests from our customers include PCD conversion, CB conversion adapters for other vehicles’ OEM wheels, or aftermarket wheels (e.g., 5×100 to 5×112 wheel adapters, wheel adapters 5 lug to 6 lug, 5×112 to 6×130 spacers adapter). Improperly wheel changing leads to the increase of driving risk. If you would like to install wheels of different sizes, wheel adapters will be your instant and most cost-effective option. Done correctly, your excellent modification will be advantageous. For more details, check on Do You Need Wheel Spacers or Wheel Adapters.
16. How thick Audi 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 various thickness spacers to meet your needs. For more details, check on How to Measure Wheel Spacers for My Vehicle.
