6 pots or 4 pots by itself doesn't say much, what's most important is the disc size. In most cases the AP 4 pots use 330 mm discs and AP 6 pots use 362 mm discs.
As far as I know the biggest softlines are 17" and I don't think they really give much clearance. So I doubt the 6 pots will fit. In fact I'm not even sure the 4 pots will fit, as the calipers might touch the wheel spokes. Although on a 2wd that is less of a problem than on a 4x4.
