You can go SDC in front as well if you want to. I considered getting these, but it would have been a long wait at the time. This thread won't be that helpful since it was from 2012 and the SDC didn't exist then. Don't worry about offsets too much as they're the same between SDC and regular concave. For a given offset and wheel width, the inner and outer edges of the barrel won't differ no matter what the face looks like. Only thing you have to worry about is brake clearance in front if you have a big brake kit. Otherwise, no worries.
