Suspension setup is all about managing compromises. You should sit down and talk to Jeff. He can help you analyze your needs and come up with a solution. Then he can order parts for you, revalve your shocks appropriately, align the car and anything else you need to get it track-ready.
Putting a large front swaybar on a FWD car has two main effects, and those effects sort of counteract each other to some degree on some cars. First, the action of the bar itself will tend to make the car understeer more. The counter to that is that some cars have such poor camber curves that limiting body roll helps them maintain more dynamic camber in a turn. This is really only an issue for STREET cars. A race car simply dials in more static camber to compensate rather than compromising the suspension to band-aid it.
So, yes, you could but a big giant front bar on your car and deal with all of the negatives associated with it. And to reduce the understeer you created, you would HAVE to put either really stiff springs or a really big rear swaybar on the back. But, you'd end up with a car that was so stiff that it wouldn't handle road imperfections well at all. Since all of the roads and race tracks that we drive on are far from perfect, I never think of this as a good compromise!
Talk to Jeff. Bring your checkbook.

Loren is dropping that knowledge just fine. Ultimate setup is going to be course dependent. a car set up for aggressively might lap other tracks quicker slightly more aggressively. the idea is to find a good compromise.
The current "hot" setup is active Aero on FWD cars, and spring/damping them slightly too stiff in the rear. this way the slow corners they oversteer, and the faster corners they are stable.. but I've driven the same FWD car before and after a splitter and you would not believe the difference.
Now A FWD setup for a smooth track with a lot of slow corners can see the rear spring rates eclipsing 1000lbs on a light car. but that same setup will kill your lap times at sebring.
