Don't forget about brakes. If you have a drum rear currently in the car and get a 4th gen w/ discs, you would need to install an adjustable proportioning valve which isn't a hard task...I believe the e-brake cables are different as well, to take up for the 2" difference on each side. I know I had to change mine, as well as the routing location underneath the car.

4th gen rears go anywhere from $200-400.

Edit: You can run 3rd gen wheels, it just won't sit as it did before, it would have more of a bulldog stance...and if there is enough body roll and you don't roll the fender lip, it can bump the tire a bit. 4th gen backspacing as Justin said would correct that.
