I have a 2013 with a 4" and just like the shop told me, I should have gone 6" because I am always wondering what if. My goal is to run 35s without any rub, and hopefully very little trimming. I am now shopping 21s and because of the above, I am thinking that I want a 6" right from the jump. Your leveled pics look great, but if I am going to put the money into the work, rims, and tires, I figure I might as well go for it all. Any reason not to? Does BDS have a kit for 21s yet? I had a dealer tell me they could do an RC 6". Thanks in advance!
