Guys I have couple of questions

I've heard on an AWD car can't put different sizes of rims and camber kit either

Why is that? What does it do bad to the car?

Thank you in advance

 

For the AWD system, different size wheels will screw with it. Your wheels have to be rotating at the same ratio for the AWD to work, so getting 19x9.5 and 19x10.5, the wheels are two different weights and will rotate differently. Some have done the staggered wheels and offset the weight with different sized tires.
