205/50/17 is WAY too tall, even if you got the offset perfect you would still eventually jam one into a front fender and pull it out badly. 215/40/17 would be the size for those.
8mm is enough to make the wheels non-hubcentric, which is why I never recommend such a spacer. 5mm is possible to get away with, otherwise 15mm is the next step. So I would try to use 5mm and if that doesn't work, 15mm all around with 205/40/17 tires (this will look awesome).
Also, make sure the wheels themselves are hubcentric or at least have hubcentric rings (meaning that they sit snugly on the hub without any play).
