How many times will I have to replace the struts/shocks if I get my car lowered?
 

If I get my car lowered and say the stock struts and shocks go out in a year (I don't know the average time) will I have to replace them again in same amount of time? That would really turn me off from the idea of lowering my car...

In order to properly lower your car, the shocks/struts need to be replaced with ones designed for that purpose. The quality of the parts you buy will determine their life expectancy. High quality shocks/struts designed for the amount of drop you are going to do should equal or exceed the factory equipment.
