ah! mmkay, now i see where you're headed.
if you are worried about adverse tire wear when lowering, that would be more of a possibility with the rear tires than the fronts. our front suspension design doesn't take on all that much neg. camber when lowering, and the little bit that it does will actually help your car handle better and not run so heavy on the outside shoulders of your tires when turning harder.
depending on how you drive, its possible that with enough neg. camber, your rear tires outer shoulders would see little to no action. overall, for both handling and tire wear concerns, running around -1.0 to -2.0 degrees of camber is safe...and then just making sure to rotate tires as you should with any car (roughly every 6000 miles is good).
now, to more directly answer your question: if you had 1.75 degrees of neg. camber adjustability, then that should probably be able to return you back to stock or near stock settings almost no matter how low you drop your car.
of course, you can always go check out the other stickies and see that staying at or near stock ride height could possibly grant you a better handling car than most setups that drop your car an inch or more.....
but that's a whole other discussion.
