Several days ago, this BMW 5 Series G38 installed BONOSS Forged Lightweight Plus Wheel Spacers, front/rear 10mm (2/5 inch), PCD 5×112, CB 66.5 together with BONOSS Forged Shell Type Lock Bolts Kit. Why install a set of wheel spacers? It allows for installing larger wheels and tires without breaking the fender. 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. These spacers and bolts are specifically designed to suit this vehicle and intent to improve handling performance, moreover, achieving an excellent look. They match perfectly with the BMW wheels, due to the 0.02mm precise process.  (Thanks PERFORMANCE CENTER for providing these pics)

Are wheel spacers safe on BMW 5 Series G38?

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.

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 OEM hub, ensuring a firm fastening. The tensile strength is higher than 1200 Mpa, meaning they can bear numerous stress cycles without damage.
