Reducing body roll. SS springs, sway bar, or both?

I was running 002 and 003 SS springs on my Demon with 275/60-15 tires on 15x8 rim with 4" BS. When I changed to the new tires , 295/60-15, I switched to 002 on both sides. 15x8.5 rim with 3.25" BS. Does not rub during any street driving or driveway approaches. Not sure what you are trying to fit the tires in, but I love the SS springs.
