Project Description


Performance upgrade! Yesterday, this BMW 4 Series Gran Coupe F36 installed BONOSS Forged Lightweight Plus Wheel Spacers, front/rear 15mm (3/5 inch), PCD 5×120, CB 72.5 together with BONOSS Forged Grade 12.9 Extended Wheel Bolts. Larger brake calipers with more pistons will offer greater stopping power and shorter stopping distances than the OEM ones. However, bigger calipers will take up some room of the wheel installation area, so that the wheels cannot be mounted back with a proper engagement. If you have upgraded your brake system with bigger brake calipers and still want to keep the current wheels attached to your vehicle, wheel spacers will be your most cost-effective solution.  (Thanks to the owner for supporting.)

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.

BONOSS Forged Grade 12.9 Extended Wheel Bolts

After installing wheel spacers, the factory wheel bolts will not be long enough, reducing the number of laps for threading. In the case of intense driving, it will cause kinds of security issues. Thus, need a new set of extended bolts. High-quality bolts for a high-end vehicle. BONOSS Forged Grade 12.9 Extended Wheel Bolts applies SCM440 high strength steel material, which provides extremely high performance. The size is completely fit the vehicle hub, ensuring a firm fastening. The tensile strength is higher than 1200 Mpa, meaning they can bear numerous stress cycles without damage.
