Active Cooling – Core Technology of BMW i4 Wheel Spacers

This design is the world’s first patented technology of BONOSS BMW i4 wheel spacers, and the series products were named “BONOSS Forged Active Cooling Wheel Spacers”. Most ordinary spacers in the market are only designed with smooth flat surfaces, while BONOSS applies the aerodynamic theory to BMW i4 wheel spacers. The heat dissipation grooves are distributed as like petals. This curve design can accelerate the airflow in the wheel system. The normal work of brake systems, wheel spacers, and wheels can be protected with the “Active Cooling” tech.

As the product name shows, “Forged” is also an important point determining BONOSS BMW i4 wheel spacers’ quality. Forged BMW wheel spacers have a more smooth surface, higher precision, and more stable structure compared with the casting adapters. That means spacers can be fitted to the axle hub tightly without vibration or rubbing problems. Some shoddy products have a rough mate surface and improper PCD(Pitch Center Diameter) and CB(Center Bore) with stock specs, which will cause severe damage to customers’ other components and their safety.
