Tire rub issue with 285/60/20

Hello. I am Jay2theU from So Cal. I just purchased and installed -12mm offset 20x10 Fuel Throttle wheels and Nitto exo grappler all terrain 285/60/20 on my 2014 Tundra limited with TRD package and spacer in front. I am not an off-road enthusiast yet but want to take my truck out for adventurous trail rides in the future. However, going with the aggressive look, My front tires are rubbing against the bumper (minor) and back wheel well and the frame. Americas tires advised me to trim the bumper and cut small portion of plastic well and to hammered down the frame to make it smoother with no sharp edges. This was the most inexpensive option and live with minor rubbing when I make full turns. I am still not sure if I should lift the truck for more clearance or do a frame modification specified here in this website: http://www.off-road.com/trucks-4x4/project/fixing-tire-rub-from-large-offroad-tires-53862.html

Any recommendation from Tundra experts are appreciated. If lifts are recommended, please give some reputable brand suggestions.

If your close to them I would have them do the cmc for you. If you can do the job yourself @Relentless fab on this site can hook you up with the plates. If you would have went with less offset on your wheels you probably won't have any issues.
