even more involved would be struts, brakes, rims, lower....let the rotor size determine wheel/rim size.

agreed , rims then lower... you may need to roll or pump the guards before lowering on your choice of rims

Get the rims first or you may have problems with guard clearance on the front because unless the wheels are the perfect offset ( as most wheels you get aren't unless specified for a particular vehicle they will scrub so if you can find out the offest of the wheels you want first you will know , the wheels i have on my car 185-60-13 are the same as the 165-12 that were on there but I had to roll the front & rear guards so the dont scrub before I lowered it .

jus wondering about rims after i lower my ute.
are there any troubles in doin so, if the rims im gettin are same overall size but smaller as low profile?
need to know......
