just make sure that where you are buying them they are 5x112 66.6 wheel to 5x120 72.56 hub. i just searched and different sites describe them reversely. you could buy custom adapters from motorsport-tech.com. they came out to around $240.
can't wait to see the alphards on your car! i've wanted to put them on my car, but didn't want to deal with adapters.
