i think (not positive) the more u lower a car the more negative camber u give it. because u've just changed a dimension in ur cars suspension which other pieces relied on in making the wheel have positive or negative camber. u can get adjustable camber plates in which u'll have control on how much - or + camber u have. so like i said:

lower the care = more - camber

which affects two things: handling and tire wear

have fun rippin the turns lol
