Wheel Choice for e30s is a little slim. There is a new wheel coming out for the e30 in Sept. It is fairly cheap ($99) and looks good. (not sure of the back spacing yet)
The problem is the Manufacturer lists the production weight at 12.9 lbs. In reality the wheel will be 13 lbs or a little over.
So how does Nasa/spece30 decide if your wheel is of legal weight? By actually weighing the wheel without the tire? or by what the Manufacturer states the wheel weighs?
