How much clearance do you have before hitting the bump stops on your lower arms?

Tires do make a difference in the way a car handles,
but if the suspension is not setup properly travel wise
you can forget any kind of performance handling.
If your on the bump stops whats the point in
shocks or swaybars not to mention any alignment gains.
All your doing is bashing the a-arms and stressing
the steering components.
You might run drop spindles to lower the car without
compromising handling.
QA1 has some decent tech on the subject as do a lot
of other shock and steering component manufacturers.
