maybe black out the chrome ? flares are ok ... only reason i keep mine on is so i dont get a ticket ... without them in Cali my tires would stick out too far .. imo i would do something about that bumper tho
i voted wheel spacers because you don't really get an appreciation for how bad it looks until you're following your truck down the road without spacers on the rear, just looks absolutely ridiculous haha.
But then a front bumper would be second from my perspective. We have tons of deer in this area and there are a lot of expensive front end goodies in the front of our rigs, so it was a no brainer for me. If its just for looks then i wouldn't, just my 0.02
If you do a lot of towing i would suggest the steel spacers from wheeladapter.com
but if you don't then you should be able to get by with aluminum ones, i've been running mine for almost 10k now just checking the torque every once in a while. I paid less that 100bucks shipped for mine, don't remember the exact price, but i got them from rocky mountain suspension. you can find them anywhere though.
