Lowering & Expected Camber Changes   If you are planning to LOWER your vehicle BELOW MFG'S factory ride height, you can expect camber angles to change approximately as follows:  

Camber is the inward or outward tilt of the tire/wheel assembly.
This angle is measured from a true vertical line, i.e. perpendicular to the ground. A tire/wheel assembly that is tilted outward at the top is considered to have Positive camber. While a tire/wheel assembly tilted inward at the top, displays Negative camber. For a zero setting, the tire/wheel assembly is in the exact vertical position or perpendicular to the ground. To rephrase, if the top of the tire/wheel assembly is tilted inward towards the engine, it has a negative camber. If the top of the tire/wheel assembly is tilted outward from the engine, the camber is positive.

This is Negative Camber    
 

This is Zero Camber      

This is Positive Camber
