Not a daily driver.
OK. What is it then?
Drag, track, autocross?
What is the driver's skill level?
What kind of shocks do you plan to use?
Gonna use coilovers?

Garbage in... Garbage out.

1kg/mm front no sway bar.
20kg/mm rear with a 42mm sway bar.

I found this to be a good stable setup that is lift throttle friendly.

I plan on using it mostly for Autocross, have about 2 years of autocross and 1 road race. It will be used to autcross once a month and will be road racing 2-3 times a year. I am looking into the koni yellows, and eibach ers springs.

1991 honda Civic si hb mods include:
-b18c w/ lsd
-roll cage
-no suspension modifications as of yet
-car is stripped if that matters.
-15x 6.5 wheels

Granted, the original post could have asked his question better, done some research on is own - but is this type of sarcastic respnse really necessary? If you don't want to help the guy, just don't say anything - don't give him misinformation and think it is funny...

The consensus here for a daily driver and halfway serious auto-crosser seems to be a bias around 400F/600R using off the shelf, or revalved Koni's with a larger rear sway bar (say 22mm) and a stock front. This will give a decent amount of oversteer depending on tire pressures.

Also, it seems you want to run higher if you plan to roadrace because the tracks tend have a smoother surface with less harsh of transitions which suits a higher spring rate better. If you go higher than 600lbs/in, you will want to revalve Koni yellows which costs about $125/shock.

EDIT: If this isn't a daily driver, and will see double duty between track and auto-cross then plan accordingly.
