One thing I found with mine was that the front wheels would not fit onto my 11.75 inch rotors. The hole in the center was not big enough.

I took them back to the factory and they re-cut the centers on all four to a larger size (so they matched) with bigger center caps.

As it happens the guy that distributes the wheels to dealers in the US was there so I told him to tell the US outlets to make sure these wheels are cut to fit Mopar discs.

I saw his again a few months ago at a show and he assured me he has informed the US dealers.

Yes, a good chunk of that is shipping, from the factory in England to the distributors in the US, then from distributors to the buyer. I forget the exact cost, but the per wheel price was actually pretty decent.
