1. Are Mercedes Benz GLS-Class X166 wheel spacers safe?
In general, the material of these X166 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 Mercedes Benz X166 spacers are safe as long as you use the high-quality ones and install them correctly. The tensile strength of X166 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. For details, please check Are Wheel Spacers Good or Bad.
2. What are the size of Mercedes Benz X166 wheel spacers?
The data of Mercedes Benz X166 wheel spacers is Bolt Pattern (PCD):5×112, Center Bore (CB):66.5, Thread: M14x1.5
At the same time, the 5×112 wheel spacers can also be used as Mercedes-Benz AMG GLS 63 wheel spacers, Mercedes-Benz GLS 450 wheel spacers, Mercedes-Benz GLS 400d wheel spacers, and Mercedes-Benz GLS 580 wheel spacers.

3. Will BONOSS Mercedes Benz X166 wheel spacers cause vibration?
Actually, the wheel spacers just increase the wheel track and the grip. Mercedes Benz GLS-Class X166 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. For details, please check Why do You Need Wheel Spacers with Hub Centric Rings.

10. What is the difference in vehicle handling experience after installing BONOSS Mercedes Benz X166 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.

11. What kind of Mercedes X166 spacers should I choose to fit other brand wheel rims such as BBS wheel rims, Vossen wheel rims, OZ wheel rims?
Mercedes GLS-Class X166 wheel spacers, wheel studs, and lug nuts are equally important to the wheel. An excessive positive offset will cause friction between the inner side of the rims and the suspension components. In this case, installing wheel spacers can provide the clearance required to avoid friction between the inner side of the rims and the suspension assembly, and correct the deviation by pushing away from the rims. Mercedes Benz X166 Wheel spacers can also be used to adapter the car’s pattern and center bore diameter. In this way, aftermarket rims with different data can be installed. For example, BBS wheel rims, AMG wheel rims, AEZ wheel rims, Antera wheel rims, OZ wheel rims, and Vossen wheel rims. Compared with those cheap cast spacers, BONOSS Mercedes X166 spacers are safer and more professional. For more detail, please click When to Use Wheel Spacers for Aftermarket Wheels.
12. How do I choose Mercedes Benz GLS-Class X166 spacers for avoiding the problem after installing Prior Design brakes, AP Racing brakes, Brembo brakes, or other brands?
High-performance brake kits are usually larger than car parts, and the caliper usually cannot be accommodated in the original rim space. By replacing a larger rim, a suitable gap can be obtained and avoiding friction between the rim and the brake caliper. If you have installed a larger brake caliper and want to fix the current wheel on the vehicle without scratching, installing the Mercedes X166 spacers will be the most cost-effective solution. Mercedes X166 wheel spacers can be adapted to Brembo wheel brakes, AP Racing wheel brakes, Prior Design wheel brakes, EBC wheel brakes, Endless wheel brakes, and Alcon wheel brakes. Compared with those cheap cast spacers, BONOSS Mercedes Benz X166 spacers are safer and more professional. For more detail, please click When to Use Wheel Spacers for Big Brake Kit.
13. What kind of Mercedes Benz X166 spacers do I choose to fit the body kit or aero kits?
Usually, wide-body kits including the upgrades of larger-size wheels and bigger brake kits, and the Mercedes Benz GLS-Class X166 spacers allow adding larger wheels and larger brakes. This is a very safe upgrade if you are going to drive a wide-body car on the track. Installing spacers is the simplest and most effective modification to low the chassis, widen the wheel track and make the wheels flush with the fenders. Mercedes Benz X166 wheel spacers can be matched with AMG wide-body kit, Brabus wide-body kit, Carlsson wide-body kit, Liberty Walk wide-body kit, and Hamann wide-body kit.

14. How to choose Mercedes Benz X166 wheel adapters for installing Audi wheels, BMW wheels, Porsche wheels, or other else?
For the same wheel bolt pattern, we can customize a 3mm to 160mm wheel adapter to fit the wheel, and what you will need to do is check the thickness you need and contact us. In some sense, the Mercedes Benz X166 wheel adapters also play the role of wheel spacers increasing the wheel track. Because wheel adapter can push the wheel outward too, and make the wheel flush with the fender. At the same time, it can also be used to solve the gap issue of brakes, tie rods, and other suspension parts. Compared with spacers, Mercedes Benz X166 wheel adapters can change the PCD and the diameter of the center bore so that you can install wheels with different data. In brief, installing wheel adapters make the vehicle obtain better turning performance, a smoother driving experience, and a fuller appearance. For more detail, please click Do you need wheel spacers or wheel adapters.
15. How to measure and determine the thickness of the Mercedes Benz X166 spacers?
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 Mercedes Benz GLS-Class X166 spacers have a thickness of 3mm-20mm for choosing. For more detail, please click How to Measure Wheel Spacers for My Vehicle.
