With a body kit, you really need the big rims to pull it off. While 18's will ride, handle and perform better, they won't suit the rest of the build IMO.
Go the 19's like you want to. Great thinking.
Instead of the radiator... perhaps a process west V mount while you can? cross both the intercooler and the radiator off your list in one hit :P
