FAQ&TIPS

1. Are BMW E Class wheel spacers safe?

In general, the material of these BMW E Class wheel spacers is steel or aluminum. They are installed between the hub assembly and wheel, pushing the wheels out and increasing the wheel track. The Porsche Panamera spacers are safe as long as you use the high-quality ones and install them correctly. The tensile strength of BMW E Class wheel spacers can resist great tension before breaking. Compared with some cheap cast wheel spacers, BONOSS forged wheel spacers are safer and stronger, the tensile strength ≥ 310Mpa (AL6061-T6), and the tensile strength of cheap spacer is about 125Mpa. When faced with bumps and impact loads, the higher tensile strength can withstand greater force without breaking.

2. What are the size of BMW E Class wheel spacers?

The data of Porsche Panamera wheel spacers is Bolt Pattern (PCD):5×120, Center Bore (CB):72.5, Thread: M12x1.5
At the same time, the 5×120 wheel spacers can also be used as BMW E Class wheel spacers.

3. Will BONOSS BMW E Class wheel spacers cause vibration?

Actually, the wheel spacers just increase the wheel track and the grip.BMW E Class wheel spacers can be used to correct the offset or solve the gap problem of larger brake kits. We recommend using the hub-centric wheel spacers, they can provide a better support and stability system. Their design purpose is to establish a tight connection between the wheel hub assembly and the wheels to ensure that the wheels bear the weight of the car. To make the spacer more fit the wheel hub assembly, the BONOSS spacers adopt the multi-stage hub-centric design and precision 0.02mm CNC machining, which effectively guarantees the safety and reliability of spacer quality and provides higher stability. Thereby reducing high-speed vibration, so it is safer.

4. How does the active cooling technique of BMW E Class spacers work? Why it is a breakthrough for traditional spacers?

The back of the BMW E Class spacers has specially petal shape grooves. Because the rotation of the spacer makes the external cold airflow efficiently and continuously inside the spacer, while cold air flowing, the heat of the braking system is taken away, thereby achieving the effect of active cooling, improving braking efficiency, and reducing overheating of brakes. This technique maintains the brakes at normal temperature to ensure wheel spacers’ safety and driving security. For a long time, the function of the wheel spacers for cars is single. As a professional spacer designer and manufacturer, BONOSS relies on years of experience and hard work to create the world’s first active cooling technique, diversifying spacers’ functions and increasing the value. On top of that, the production cost of the active cooling technique is almost the same as traditional spacers. So that customers scarcely need to pay extra for this. It is precisely having more functions, higher performance, and more friendly wheel spacers prices that have become the choice of many customers.

5. What are BMW E Class spacers make of? How do they stand out from the common?

BONOSS forged BMW E Class wheel spacers are made of high-grade 6061-T6 aluminum alloy. Due to the continuous stress cycle and deformation process, forged wheel spacers become stronger and stronger, and their strength is greatly improved. This metal has good mechanical properties and taking AL6061-T6 as an example, its tensile strength ≥ 310Mpa, yield strength ≥ 275Mpa, and failure elongation ≈ 10%. Compared with industry standards, the cheap spacers which using low-quality materials are not strong enough and will deform and endanger driving safety under strong impact. In contrast, BONOSS insists on producing professional BMW E Class wheel spacers far higher than the industry’s safety and professional standards.

6. hat is the performance of the wheel studs and lug nuts in BMW E Class spacers? Why does each have the BONOSS Logo?

The BONOSS wheel studs and lug nuts passed the reports and reports tests. The matching wheel studs applied JIS SCM440 steel material, and it has many desirable properties such as high strength, wear-resistance, excellent toughness, and impact resistance. It also has good ductility and high-temperature stress resistance, structural stability, low harmful elements, few surface defects, and more advantages. Besides, it has achieved ISO standard grade 12.9, taking M12x1.5 as an example, its tensile strength ≥ 1220Mpa, ultimate tensile load ≥ 152000N, hardness (HV) ≥ 395, NSS ≥ 500H… The matching lug nuts applied 40Cr material, by continuous forging process, they have achieved ISO standard grade 10, and its proof load ≥ 1110Mpa, hardness (HV) ≥ 349… They can easily withstand hundreds of strong shocks for normal driving and sufficient to cope with intense racing competitions. This excellent performance stems from BONOSS’s professional and dedicated attitude, as evidenced by the BONOSS Logo on each product. BONOSS insists on producing professional BMW E Class wheel spacers far higher than the industry’s safety and professional standards.

7. Why do BONOSS BMW E Class wheel spacers have reports and reports test reports?

That’s not only for getting the trust of customers, this is also BONOSS’s confidence in product quality. BONOSS has completely passed more than 66 ISO standards reports, Reports authoritative tests, and achieved excellent results. BONOSS matching wheel studs have passed reports 2,000,000 times the limited life test, without damage. Taking M14x1.5 wheel studs as an example, tensile strength ≥ 1282Mpa, ultimate tensile load ≥ 152000N, hardness (HV) ≥ 395, NSS ≥ 500H… Through these authoritative test reports, BONOSS truly achieves the quality and professionalism expressed, in the form of data, which truly guarantees safety. BONOSS believes that high standards of quality management and authoritative certification reports are the best way to meet customer and regulatory requirements.

8. What are the benefits of the knurling design of BMW E Class wheel spacers?

The knurling design can expand the side which can heat dissipation contact area so that it can contact more external cold air, enhance the heat dissipation effect, and reduce the internal stress of machining. Besides, upgrading the performance, strength, and durability of the wheel spacers. On the other hand, adding the knurling design on the side enhance the aesthetics of the BMW E Class wheel spacers. BONOSS aims to provide more additional functions for the Porsche Panamera spacers, and make the spacers safer, higher performance, and have a better installation experience. This is the reason why BONOSS insists on independent manufacturing and continuous optimization of the design. In addition to practical functions, there is a sense of art.

9. What is the difference in vehicle handling experience after installing BONOSS BMW E Class spacers?

Wheel spacers are a cost-effective way to increase the track without changing the wheels. As the width of the track increases, the overturn resistance is enhanced, and the weight of the vehicle is evenly distributed on all wheels, thereby improving the ride comfort. When the wheelbase increases, the vehicle’s grip is also enhanced, which is very effective when the vehicle is turning. When the offset of the wheel is insufficient, the wheel spacer will compensate for the custom offset by pushing the wheel away from the hub. Large brake kits can be installed without rubbing the suspension parts by pulling the wheels out of the ideal distance. The tolerance of the BONOSS wheel spacer is 0.02mm, which is more suitable for the wheel hub, reducing the vibration of the vehicle at high speed and providing a smoother driving experience.

10. How to measure and determine the thickness of the BMW E Class ?

Use a straight edge or metal square, to attach it to the outer side of the wheel and the inner side of the fender for measurement. The distance range is the choice of the thickness of the spacer with a flush or almost flush appearance with the fender. If the spacer is too thin, you will still be affected by the wheel or caliper, if it is too thick, the tire will hit the fender. Therefore, the use of spacers of appropriate thickness can not only ensure safety but also avoid violation of local laws and regulations due to the overly prominent appearance of the wheel. At present, BONOSS BMW E Class spacers have a thickness of 15mm-20mm for choosing.
