From looking at it looks like the front end is not centered. Like the passenger wheel seems closer to the fender than the driverside. Cars lowered about 2 inches I had an aliegnment done after I lowered it a year ago, also passenger caliper is warped so it shakes quite a bit when braking. Will getting another alignment fix it?

 

an alignment will not move the wheel in or out, in fact there is no adjustment in and out.

is the entire wheel out further, or just the top? that could be an alignment issue

It could be an illusion, or the car is wrecked and "fixed", or a fender is bent slightly and bulged out further than the other. Could be a handful of other possibilities, but if nothing is obviously damaged or broken, there is nothing you can do about it.

 

maybe the front/rear wheel offsets are different, and a front wheel is on the rear, and vice versa

 

Naw, im running c6 wheels. 18"s up fron 19"s out back. From what i know the cars never been wrecked. Another question i have, is when im rolling slow and brake hard there is a popping noise coming from the driver side front wheel. Any idea what this could be?

 

Check to see that everthing is tight. That popping could be a ball joint, strut bolts,bushings, or sway bar related.
