What they do is get a 'blank' rim and go from there.others use two halves.different ways.major advantage of this is u get custom offset suited for look needed.

But if you could pick them up from otomoto for that price, that would be your best bet then.a set of four 13inch 8.5j are not cheap.and was that price quoted with tires or not?

also do you know what offset your after?as you might need to flare guards depending on offset.get an idea before ordering mate
