Wheels with a better offset are the better option as they will have the same effect without risking spacers.
Obviously a wider car is less likely to roll, Its a good idea to add about an inch in width for every inch you lift or the car would get unstable. Wider off set will also help sort some issues of rubbing, but will create some others as the wheels radius of movement will be bigger and colud now catch in the arch rather than the chassis.
