you are using "suspension geometry" as an adjustable feature? It is not really that easily adjusted. You can change it by lowering the car, like you did but you can not adjust it any further unless to change toe and camber to make it "steer" differently. But this will wear you tires unevenly.

To "change" the suspension geometry you need different control arms and suspension mounting angles.

The sport and regular "Geometry" is nearly the same. You lowered the car which is the main physical difference between the sport and the normal

First, Thank you for the answers.

I think i did the alignment that is not for lowered car spec that is so affect to my steering, I have to turn it so much when i need to turn my car in same angle as before. I have another question. Is the lowered car spec and standard spec is the same in number(something like angle, length, etc) or it is difference?

Thank you
