Like I said it depends on what you have stock and what options you go with. There is no standard number.
The biggest weight savings would be going from a stock power steering disc brake and sway bar car to an alter-k with a manual rack, no sway bar and the smaller wilwood brakes. Not sure what number would be but I do know a stock power box and steering linkage is quite a bit heavier then a manual rack. Lol.
