geez, blah blah blah, the best and safest way to do wheels is buying the proper wheels and offset. Not an expert but when spacers are use it thows off the ENGINEERING behind the part. Small spacer will be less harmfull yes but I personally not willing to risk wheel ends. One of those fall off and it is devestating, at the very least to the vehicle, hence one should torque lug nuts and yadda yadds. If u want to use spacers go ahead, I would not use such products, there is reason a (respectable) TIRE and RIM shop will only use certain products, don't want to be responsible of a wheel end failure, just cuz they are manufactured does not mean they are good, people will buy anything that is for sale. You have heard both arguments now make ur decision and put them on if u so wish.
