Project Description


A few days ago, this BMW 5 Series G30 installed BONOSS Forged Lightweight Plus Wheel Spacers, front 10mm (2/5 inch), rear 18mm (3/4 inch), PCD 5×112, CB 66.6 together with BONOSS Forged Grade 12.9 Extended Wheel Bolts. If you would like to bolt up wheels that are made with a bigger center diameter for your car, then wheel spacers can be your most cost-effective option. The hub-centric design makes a snug connection between the axle hub and the wheels, meaning no gap, no vibrations, fewer stress loads and more service life range. Besides, by pushing out the wheels to an ideal distance, wheel spacers give your car a more aggressive exterior as well as a better aerodynamics body. They fit perfectly with the wheels, due to the 0.02mm precise process. (Thanks MAX for providing these pics)

The BMW 5 Series G30 is one of the most popular luxury vehicles in the world, complete with compact dimensions, new styling, exquisite interior, comfortable seats, and expanded cabin. It has a potent powertrain, a 252-hp 2.0-liter twin-turbo engine, providing 258 lb-ft of torque, an eight-speed automatic transmission, offering smooth, sharp handling. The best bit with any 5 Series is how it drives, and BMW was always not to disappoint here. The steering is firm and precise, body control is brilliant and the handling is anything but pleasant.

Are wheel spacers safe on BMW 5 Series G30?

Technically, yes, they are totally safe. One of the essential parts of wheel spacers safety is the material. BONOSS forged lightweight plus wheel spacers applied Forged 6061-T6 Aluminum alloy, which is high strength, great toughness, and good corrosion resistance. And the Black Hard Coat Anodizing process provides the surface with better abrasion resistance, flame resistance and smoother and harder finish protection than regular paint or metal plating. They are manufactured with a tolerance of 0.02mm, which means perfectly fit, no additional force, no vibration, no annoying noise, less energy loss, less fatigue damage, longer service life.


Why do you need extended wheel bolts?

Any time you run wheel spacers, extended wheel bolts are a must option to properly secure the wheel to the vehicle hub. Without the proper thread length, the stock lug bolts will not allow penetrating the vehicle hub threads completely which can cause car shaking or safety risk. BONOSS Forged Grade 12.9 Extended Wheel Bolts are made by the forged process. The forging process offers lots of advantages over other manufacturing processes for wheel bolts, such as high tensile strength and tough, hard and durable, better wear resistance and higher fatigue strength, elimination of porosity, evenly and tight internal structure, good polishing and finishing surface characteristics.

Addtional Information:

  • BONOSS wheel spacer thickness can be customized flexibly, which is compatible with most vehicles. Thus, if you would like different sizes of wheel spacers, feel free to contact us. This BMW 5 Series G30 uses front 10mm (2/5 inch), rear 18mm (3/4 inch), PCD 5×112, CB 66.6.
  • The extended bolts are made of JIS SCM44o high-strength steel, which features many desirable properties such as high strength, wear-resistance, excellent toughness, impact resistance and high-temperature resistance. This BMW 5 Series G30 uses conical seat bolts. If you would like a set of extended bolts, please ensure the seat type of the bolts is suitable for threading properly.
  • Each BONOSS product is printed with the logo of “BONOSS”. This offers an easy method to distinguish other fake and inferior products.
