BONOSS Forged Lightweight Plus Wheel Spacers

Easy but big effective upgrade! Last Sunday, this BMW 4 Series F36 installed BONOSS Forged Lightweight Plus Wheel Spacers, front 12mm (1/2 inch), rear 15mm (3/5 inch), PCD 5×120, CB 72.5 together with BONOSS Forged Grade 12.9 Extended Wheel Bolts. Wheel spacers come in various thicknesses and dimensions, commonly used to widen the track of the vehicle, leading to more stability and better handling performance, which is why they are often used on many racing cars. They can also make a car look better by pushing the wheel away in a more visually aggressive position. A wheel spacers install is easy work that has a good effect on your driving experience.  (Thanks TAR AUTO for providing these pics)

Are wheel spacers safe?

Exactly, yes. Wheel spacers are a safe mod for your vehicle as long as you use high-quality spacers and install them properly. Wheel spacers bring your rims and tires outwards so that they can flush with the fender flares, giving your vehicle an excellent stance. Many car manufacturers will leave a certain amount of fender space for tire chains. 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. With spacers, you can fill the gap in your fenders and get a more aggressive and powerful look!

Any time you run wheel spacers, extended wheel bolts are a must option for properly fastening 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.

How to confirm the thread type and length of extended bolts?

Generally, it’s easy to figure out the correct size of bolt, all you need to do is to measure the length of your stock bolt then add the thickness of the required spacer, and that will be your ideal extended bolt length. In most cases, you need a bolt that is longer by the thickness of the spacer, for example, your stock bolts are 27mm, the desired spacer is 12mm, then the right size of extended bolts would be 39mm. But there can be exceptions. Considering the critical importance of the length of thread fully engaged in the axle hub, it’s always best to measure from the wheel bolt you’re currently using.

Additional 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 4 Series F36 uses front 12mm (1/2 inch), rear 15mm (3/5 inch), PCD 5×120, CB 72.5.
  • The extended bolts are spacer structure design, which effectively eliminates the bolts loosening and abnormal sound caused by the PCD hole coaxially deviation between hub and shaft head. This BMW 4 Series F36 uses M14x1.25 thread conical seat bolts. If you would like a set of extended bolts, please ensure the seat type of the bolts is suitable for threading tightly. And, if you don’t know the proper length, you are welcomed to contact our tech staff freely.
  • Each BONOSS product is printed with the logo of “BONOSS”. This offers an easy method to distinguish other fake and inferior products. At the same time, it also provides a way to find our after-sales service. Our products are 10 Years Limited Warranty (new products with 12 months warranty), which is an excellent and cost-effective choice for your car upgrades.
