I am trying to to decide what rims and tire sizes to go with on my LWB. I have a 2.5 drop in the front and a 4" in the rear with 265-60-15 on 15x8 rims in the front and 295-50-15 on 15x10 rims in the rear and want to go with 18" and 20" rims. Right now I am level but I would like to have a little bit of a rakeand stay flush with the fenders. Any pics or advice would be helpfull
