You are comparing significantly different wheels. BBS is a contract
manufacturer for BMW wheels along with their own line of aftermarket
wheels. The RGR model you referred to is a cold forged heat treated
wheel of exceptional strength. Many race teams use the RGR wheels on
their track cars. I'm not familiar with the other brand you mentioned
but I suspect a bit of research will show they are gravity cast or
low-pressure cast which is much less expensive a manufacturing method
No matter what brand you go with make sure to get hub-centric wheels
or your car will have a perpetual vibration caused by wheels that are
not quite centered on the spindle. It is a well know problem for
wheels that are of generic design that rely on the wheel lugs to
center the wheel.
