Thanks, and welcome! My build is middle of the road, I've got some budget upgrades, and some more expensive stuff too, but I'm really just here to show that it isn't too hard to make these cars fun!
Unfortunately, the entire suspension setup on these cars changed 2003+, so what I'm running won't work for you. Your best resource for these Panther cars is Crownvic.net, tons of info on the forums there on wheels, mods, performance, etc that spans the entire production timeline. Good luck, and welcome to the Panther addiction lol
