FAQ & Tips
1. 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. Compared with the previous generation product, the weight is reduced by 20%, the reducing unsprung weight helps the vehicle suspension system work more effectively. The overall acceleration of the vehicle and the overall comfort of the handling performance is better, and the driving is safer. BONOSS forged Lightweight Plus wheel spacers provide higher performance, more additional functions, fast customized service, and friendly service while maintaining a more friendly price, which is your best choice.
2. Why you need hub centric wheel spacers?
Hubcentric spacers offer a better system of support and stability. They are designed to make a snug connection between the wheel and vehicle hub, reducing the high-speed vibration. Based on traditional hubcentric Supra GR spacers, BONOSS has optimized this design to 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.
3.Are BONOSS wheel spacers safe?
Yes. wheel spacers are just the automobile accessories installed between the assembly hub and wheel, the wheel lugs apply a clamping force to secure the spacer and wheel to the vehicle hub. Just like wheels, tires, and brake systems, as long as you use high-quality wheel spacers and install them properly, they are safe. BONOSS is always concerned about safety. Take the 5×114.3 wheel spacers as an example, we use forged AL6061-T6 material (tensile strength ≥310Mpa), modern CNC machining by 0.02mm tolerance, the multi-stage hub centric design fits the wheel hub better. Meanwhile, the matching wheel studs adhere to ISO standard grade 12.9, and ISO standard grade 10 lug nuts, all of our products have got more than 50 TUV authoritative test reports. Compared with those cheap casting wheel spacers, BONOSS forged active cooling wheel spacers are safer, higher performance, and more professional in design. We believe more professional production offers more value for customers.
4. What’s the performance of the extended wheel bolts of wheel spacers? What does the BONOSS Engraved means?
The extended wheel bolts of BONOSS spacers applied high-strength JIS SCM440 steel material. They have achieved ISO standard grade 12.9, tensile strength≥1,282Mpa, limited life range test≥2,000,000 stress cycles without damage, ultimate tensile load≥152,000N, hardness (HV)≥395, NSS≥192H… 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 extended wheel bolt is “BONOSS engraved”, meaning these extended wheel bolts are made by BONOSS’s own factory, the quality is guaranteed, customers’ interests are protected, and BONOSS takes the quality responsibility.
5.What are the benefits of the knurling design on my wheel spacers?
The knurling design can enhance the aesthetics of the 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, boost the heat dissipation effect, and reduce the internal stress caused by machining. That means improving the performance, strength, and durability of the 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.
6.How thick 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.
7.Why BONOSS choose and TUV to test the quality of the product?
and TÜV Rheinland as the world’s famous testing service companies, standing for safety and quality. To earn customers’ trust, which is also our confidence in product quality. BONOSS has fully passed over 66 ISO standard , TÜV authoritative tests, and all achieved excellent scores.BONOSS forged grade 12.9 extended wheel bolts have passed the 2,000,000 times limited life range test without damage, tensile strength≥1,282Mpa, ultimate tensile load≥152,000N, hardness (HV)≥395, NSS≥500H… By these authoritative test reports, BONOSS truly achieves the quality and professionalism expressed in the form of data and truly guarantees safety. We believe high standard quality management, together with authoritative certification reports is the best way to meet customer and regulatory requirements.
