Is lowering your car say 2 inches as simple as buying a set of lowering springs for 200-300 dollars and installing them and balancing?

 

you'll most likely need aftermarket shocks and camber kit and alignment

 

How much does all that cost?

 

depends on how much you wanna spend, you can get some good shocks for about 240 for a set of four, and the camber kit will cost about that much as well for a good one, and the alignment is like 80 bucks at a shop i believe, but if you werent planning on installing all that yourself then you have to pay a shop a lot of money to do it
