@Owais_Yunus everything is very well explained by @hamza91, rear suspension in my car is almost stock except smaller springs.
Simply for the sake of stance it is compromise over life of tyres over and somewhat to road grip. Since most of the time I drive alone and that too on weekends only so I am good with it.
However, IMO -ve camber suits with deep dish wheels, when wheel is slightly out of fender or just inline with fender. whereas, in my car even lower end of wheel is inside body. In lowered charade u can't instll those wheels because there is no room.
I achieved this camber accidentally. I went to a mechanic for up-gradation of rear brakes, while box up he adjusted camber without wheel. And when we installed wheel it appeared to be like this.
Took the car for alignment and got 2nd wheel adjusted as well.
sorry I just rechecked photo, it is -4 degree, not -5.
