I don't know about it being like f-body handling, but my car is pretty stiff. Here goes:
G-W front springs
Moog cc507 rear springs
F-body front sway bar
HO rear sway bar
poly bushings throughout
Like I said, it's pretty stiff. No noticable body roll, handles well. I would like it to be a bit tighter, but for that I would need to change to different wheels/tires. Currently it rides on 15x8's. I never drove it on the stock pieces, they were too worn. I went with this setup after going through an exhaustive search on this forum(lots of great info in the archives if you are patient).
I have only pushed this setup hard a couple of times. One was out on the highway at 75mph to avoid hitting a car that slammed his brakes out of nowhere. Again, no body roll and the car remained totally predictable. I, on the other hand, had to pull over and catch my breath.
