Rear definitely, front, depends on the backspacing. 2.75 and less and you won't have to grind the calipers, 3" and more and you'll have to grind the calipers for the rims to fit over.
It's just a dusting on the caliper itself. The majority of the grinding will be on the leading and trailing edge of the backing plate (either side of the caliper)
No big deal, tons of guys here run ground calipers on D44's, 10 bolts and D60's.
In addition to Brian's tech article, here is a pic of the grinding I had to do to fit 15 X10 wheels with 4.25" backspacing.
Like Rene said, the backing plate (in addition to the caliper) will need to be modified a bit by grinding, hamering or both. I chose to do more hammering to the backing plate for clearance rather than grinding. I just had to grind the opening for the caliper after hammering.
As far as the rear is concerned, I had to lightly grind only one of the rear calipers on my disked 14BFF. The castings from Autozone varied just enough that I had to knock off the casting flash.
