Depends, if the backspacing is enough to clear the brembo's then they should fit, I have forgotten what the proper backspace is for SRT8's, but I'm sure it's on here somewhere.
Offset is just another way of looking at the same thing. To say offset is the correct term is a bit of a stretch. Still, neither measurement alone is adequate to determine if a particular wheel will clear the calipers. That measurement would be from the center hub out to the inside edge of the spokes relative to where the calipers sit. Thus, the reason you still may need to use spacers on certain wheels and not on others even with the same offset / backspacing."offset" is the correct term to look for when trying to find wheels. It is the distance offset between the centre of the hub and the centre of the wheel. I think 15-20 is good for normal chargers, not sure of value required for SRT
