Where possible, BBS treats the surface of all its wheel types using a dry processing method. Dry processing is a prize-winning, special processing method developed by BBS. The wheel is put through a CNC rotary milling machine and is dry processed using only an air and oil mix. Aerosols are then used for cooling. By applying this technique, it is possible to avoid the problematic use of oil and water coolant as the disposal of this coolant is both expensive and complicated. Another advantage of using the dry processing method is that all filings can be fed straight back into the material cycle without any problems.
