PS - I would second matching front springs to match slinky rears. I know slinkys are a progressive rate spring which would make me nervous to have everything matched.
I Have oversized sway bars and poly bushings all around with a 2.5 OME / heavies lift, oh and braided brake lines (Probably takes a little pedal play out, one of those "hard to tell the difference" mods). I can't imagine driving mine without the beefed up sway bars. Especially with the RTT.
