Stock rear end width
rear axle width
I believe I measured 57 inches on my SA. Track is 55 inches with 25mm offset wheels.
If you are doing an axle swap you may want to start with the wheels you want to run so you can place the wheel at the right position. Then have the axle built to suit.
Note that the 12A cars are a bit different than the 13B (GSL-SE). The wheels have different offset to compensate for this. (the SE axle is wider by some amount?)
I don't have an SE so I can not verify this.
