To do that properly, you should be looking at spring / damper combinations and anti roll bars.
The S3 is a heavy car, and to limit roll with springs & dampers only will mean you have to have them so stiff that all ride comfort is lost.
Perhaps the roads you use permit this, but where I am that sort of set up is a no-no.
You can get away with softer damping / springing if you run uprated anti-roll bars....you still have the better roll reluctance but the ride comfort is increased.
Don't forget also that the stiffer the ride in general, the less the chassis is able to cope with small bumps, and it actually is less able to put the power down.
This probably won't be a problem on a smooth dry road, but on a wet back road, it's an issue.
Sticking with modest spring / damper rates and fitting uprated ARBs gives toy the best combination of all...you get the better handling, whilst keeping the decent ride comfort and still being able to transfer all the torque to the road, wet or dry, on all roads.
