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)

There is no other two-door mid-size car that provides energetic, luxurious and enjoyable driving like the new BMW 4 Series F36. The avant-garde design, powerful performance, advanced tech features make it to be a super sports car that is as smooth as it performs, as dynamic as it expresses. The best bit with the 4 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 joyful.


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.
