I got mine a year ago - Love 'em! They ran me $170 a piece, so you seem to be looking at some fair deals.
You will need to trim the cladding for the 285/60/18s - I and several others had pics in our galleries showing where to trim and how much. You can't see the mod from outside (its in the inside front wheel well, cladding only), it was a piece of cake to do, and you'd never know it had been done if you didn't know to look for it.
I highly recommend the 'grapplers. You won't be sorry.
