Rolling the chassis

I am losing alot of traction in corners due to the chassis swaying. Im sick of the roll and everything I find is for moderate drag racing or for a strip car. Everything is just too stiff. Anyone have a street car with suspension work? any parts you recomend that are not too harsh for a street car. any suggestions of spots to hit first?
With the tokicos stiffened a bit I can get some good power slides and I am not getting too much twisting off the line. but any parts to make these better would be great to know
thanks
