does anyone know what the rule is for keeping or decreasing the stock roll-over factor for lifted ZJ's? i heard that it is " for 1 inch lift the width must increase 1 inch too" so does that mean that if someone lifted their jeep 4.5 inches they would need to increase their width by 4.5 inches to keep it stock?

Keeping it simple, it'd be at least 2:1. For every inch up you'd need to widen two in width; one inch on each side of center. Course, this is really simple and doesn't take into account changed spring rates, swaybar removal, heavier tires, or phase of the moon. To me it's one of those "long enough to reach the ground" things. After a while you get the feel for when the upside lightens and start taking it easy. A 4"+ lifted offroad setup will never be as nimble onroad as stock.

To keep the stock roll over factor the height/base ratio must stay the same. This means that if you go up 4.5" then your width must increase 9". This is why stock jeeps are usually more stable. It is hard to go that wide.

that might be fine for trail rigs, but you'd never be able to balence a wheel with fluid in it, thats why fix-a-flat is a last resort, and shouldent be left in.
