I wanna stance out with tt lca poly bushings coils and ls/tt brakes. Heard of negative camber. do they drive like that or do they got bags. If theu drive like that is it bad on the tires?

Z30 is the short name for our Chassis, also called a JZZ30 or a JZZ31 or the SC400s are called a UZZ30, 31, 32.
Camber is number of degrees of the wheel/tire on a vertical plane.
The actual reason you want negative camber is you are trying to maximize the contact patch of the tire on the ground during a corner, as the more tire you can get on the ground at any given time, the more grip you will have.
Race cars for examples will dial in their negative camber depending on their setup, track conditions and what they are trying to get out of the car.
Here is a Australian V8 supercar, they run quite a bit of camber, you can see it on both front and rear wheels:
As that car is thrown into a corner, the body will always lean over towards the outside of the corner, as the car leans over, the tire with negative camber will have a greater contact patch with the road, giving it more grip through the corner.
Now here is a car that has excess camber for "Looks"
The car above will eat through tires like crazy, but that is the price you pay for that "Look" and the handling would be horrible, if not down right dangerous. However a bit of camber is awesome, and the amount will depend on your setup, but generally something around negative 1 through 2 degrees in the front is ideal, and maybe around negative .5 through 1.5 for the rear would be ideal. Also camber plus toe(in or out) will eat through tires quicker than camber with 0 toe. However I feel the added handling and performance is worth the small amount of excess wear you will get, but you have to weigh the pros and cons yourself.
Hope this helps.
Thanks,
