Haha its funny cause i also have a fx4 and i am on a 6 inch lift and 35 toyo mts and i have 20 inch wheels. And check out mambe m1 m2 and m3's they are chrome and black and not gunna break the bank too bad. Here's a pic of my truck.
I think the first truck with stock 20s looks good. I'll be going in a similar direction, adding everything on by the end of the year. A lot of stuff already sitting in the garage. I'm keeping the stock 20" rims, I think they look good.
