Are they 17's or 18's?
As has been said, you will need adaptor plates (say hello to a Yellow Sticker if these get found, and any carsmart cop will
find them - around here if you have AU copies on an E series you can expect to be pulled over), and i THINK they would require you to roll your guards so you can actually turn them? Not sure on that one.
If it were me I wouldn't put em on, I'd maybe buy them then sell them again for a higher price and buy some nice wheels that have the correct offset. But that's just the devious inner child in me coming out
