Man, I like those '08 20's on that '00. Is that stock height, or is it lowered in the rear any?
Stock front, the rear is questionable. When I bought it there were 2 extra leaves per side, it was a good 5" or so higher in the rear, (it had a 1/4" plate steel slide in rack for carrying gas bottles and a liftgate). I pulled those leaves and put in drop shackles, it also has spring clamps on the front of the overloads, pulling it down about another 1", I didn't snug them down all the way though because it was too rough.
I'm torn, I'd like to go lower, 3" dream beams, and fab up a flip kit for the rear, but I'd have to change up my exhaust because the 5" is close to the axle as it is, and I would hate to go to any smaller of a tire, the rpms I turn on the highway (which I do a lot of) are higher than I'd like. I've considered putting the rear back stock and doing a leveling kit up front with either 275/65R20 or 35x12.50R20 on the OEM 20s, or maybe even some 33s on 20x12s.
But likely it will stay just like it is for a long time, or be traded for a crew cab, house and baby are the priorities right now.
