Those will be fine
In fact, I am glad you posted this here as I was in General section earlier and someone linked the same wheels in
***THIS*** post. I mis-read the AM page and thought they were 10" wheels. As a 9" wheel, the off-set will be fine.
As for fitment, I would expect them to be about 1/4" deeper under your ride than an average 9" wheel meant for your ride. The "normal" off-set is +24mm and at +30mm you will be just a tad deeper.
Pretty sad that the Tire/Wheel moderator was incorrect on fitment, huh
