Cant speak to the the NA rims, but the SRT rims are pretty stout from my perspective.... I took the Aero on a cruise to WY in July and was cruising at 82mph most of the time (75 limit) and hit some very abrupt bridge junctions and sunken spots that jarred me and the car... I found one spot on a front tire where it pinched a little rubber off that little rib next to the rim and put a small dent in the edge of the rim.... other than that they are fine....no wobbles, warps or leaks......(whew!)
