Ground Control

For people who own this or any other brand. My main concern is the tread being worn out really fast. I know you should purchase a camber kit but what's the use of a camber kit if you get the car alligned with the camber kit and then you slam it later. Isn't this going to go out of factory specs anyway? I mean if u use the ground control at maybe a 1.5 drop then likely u don't have to use a camber kit. But if you decide to drop it more then chances are, camber kit becomes a neccessity. I want to get ground controls but i do not want to get a camber kit.
I want to drop it about maybe 1.5-1.7 all around for daily use and sometimes slam it for a maybe a week or less just for show and then rise it back up to 1.5-1.7. If this is how I'm going to use the ground controls will my tire wear be ok?
I still don't understand what's the use of getting your car alligned with coilovers.
Someone please clarify, thanks.

When you raise and lower your car you can never get it back to the same EXACT specs as before. Which in turn will throw off your camber and toe. Everytime you raise or lower your car you should get an alignment. I don't know many people who can do an alignment right there.

With a 1.5" drop you shouldn't need an alignment. Your tires start to wear quickly when you go 2" or more of a drop.

Lets say you drop your car 1.5" and then get an alignment. Then you go to a car show and slam it to the ground. Then after the show you raise it back up to what you think is 1.5" again. You may or may get it perfect, you may get it within .1", but that .1" will throw everything else off too - toe, camber, and now that one side is off.

Also at car shows you can never be too sure the ground you are on is level. Heck even my garage is off by a bit and the only way to correctly drop your car is to have it corner weighted so that means an even amount of weight is on each corner so the car behaves equally left and right.
