spring relo: offset vs. mini tub for handling?

No I don't. My car is still in build process, but I am going with Hotchkis springs, shocks, & sway bars. Adjustable strut rods & upper arms. Chassis stiffening from USCarTool. I will probably run Radial T/A's on 15's for street cruising & shows, but I plan to have a set of 17s for track & corner carving. I hear good things about Continentals.
