Too many variables. Tires, tire miles and age, temperature, pressure, state of the suspension. As well as road conditions. So you need to have a feel for what the vehicle will do. A hard and fast rule could kill you. I suggest pushing the limits slowly on a corner or curve that you travel frequently and slowly get to know how the vehicle feels and responds.
If you want flatter cornering, get a SAS rear sway bar. It costs around $130 and is easy to install.
The NG900 and 9-3s share a front suspension that has may rubber mounts and bushings that allow the geometry to distort with accelleration, braking and cornering loads. There are numerious things thay you can do that are unfortunately expensive. The Viggen rescue kit (VRK) eliminates most of the rubber bits and makes the cornering much better and very responsive. This will cost over $800 for the complete kit and about $300 to install the whole kit. It has a steering rack brace and an aluminum clamp to replace one of the steering rack's rubber mounts. The control arm rubber bushing mount is replaced with a steel spherical bearing and the lateral and lower control arm oil filled hollow rubber bushing is replaced with a urethane bushing. There is also a sub frame brace to stiffen the subframe which carries the lateral control arms.
Stiffer and shorter springs can reduce body roll, but not as pronounced as the SAS rear sway bar. Lowered springs can increase the risk of damage to the suspension and engine from severe pot holes. So you may need to consider such factors.
While the stiffer springs and rear sway bar will reduce body role, the complete steering dynamics are altered with the rear sway bar. There are some complex interactions going on with body role that go away with a stiff rear sway bar. So you gain some things and loose some others. You have to get used to driving a completely new system.
The above deals with body role and vehicle role response.
The VRK will make the vehicle steer so effectively in corners you will find that you can corner much harder. It is like the front outer tire did all of the steering in the stock system and with the VRK both tires start to develop effective cornering loads. Thats the way it felt on my NG900 at 110000 miles when installed.
