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

SS springs are drag race springs not handling springs. If you notice, many of the SS sprung drag cars set a little crooked due to the spring packs having different leaves in each pack. You didn't mention what car you are working with but you may have to do some pretty serious homework to get that tire to fit. It probably won't fin up in the wheelhouse because of the width. Are you running them on 10" wide wheels?. Trim the wheel lip or roll the edge? XHD springs that don't move much or 1" or 2" over height springs for more clearance? Way too many details left out to have a good answer for you.
