IIRC, when running the LS wheels you do need a different type of lug-nut, as pictured in Bangster's link. I highly suggest NOT getting the Ford lug (they mushroom), at the time I bought my set I used the Chrysler Sebring Convertible lug (don't know the part number). They've held up very well, no corroding/mushroominging etc.
But due to the depth of the nut past the washer, you may need to either double washer the nut or have a spacer that has big enough of a hole around the stud to allow the shank of the nut to not touch the rotor. Either the bottom of the nut hits the brake rotor, or the end of the nut pops out from the stud bottoming out. Can't remember which.
I'm running big fatties (255/55/17 rear, 255/50/17 front) on my LS wheels, but since the car has been parked for a few years now I can't remember all the details with how+why my setup is the way it is.
Oh, and I think the spacers I used were 7/16", just enough to keep the fat fronts from rubbing the spindle. With a skinny 215 you may not need one.
