i dont think so, you can still find plenty of wide 4 lug wheels. my buddy just picked up a set of Kakimoto wheels that are both 4 and 5 lug, the front were 16x7.5 the rear were 16x8.5 -- I was pretty impressed, dual bolt pattern AND good size/offset, not bad.
They ARE out there, you just need to search further than tirerack and wheelmax.. guys.
