Yep that is a good question , I am interested to hear what is said.
Yes the color is not the same as the orginal color of the wheels. So order yours bare and spend the money to get them blasted and painted correctly. The wheels can be orderd bare , at least from me they can, no problem.
As far as being straight , most are within factory tolerances , and those are pretty loose.
