When I bought my car it had an Arizona Z coilover setup (w camber plates) on it and polyurethane bushings all the way around coupled to 16x8. I've replaced the tires with 245/45r16® and 225/45r16(f) (falken's). The springs are about 300# all the way around.
Although the car handles like a race car (that's actually what it was in it's previous life) I'd have to say that unless your roads are perfectly smooth you may want to consider keeping more stock components than mine has.
Yes...it is a very stiff (rough) ride, but, I do drive it almost every day (or at least I did until it started spitting raw fuel out of that fuel pressure regulator looking unit beside the fuel pump) so, I guess it's liveable...not something you'd want to impress your girlfriend with, though...
On the other hand, as hard as I try, I can't make it fishtail. I've tried to get it to...but, all it does is let the inside tire spin a little and continues to turn normally, throwing you almost out of your seat.
I have a GTech and one of these days I plan on measuring my lateral Gforce just to see what I can get out of it.
Few cars can outhandle a built suspension'd 1G Z (imho), especially if some weight is removed here and there.
