Lowered car alignment questions

[dedoom]

So! I am still learning how car suspension works so bear with me please. I've read multiple threads and the common knowledge is that to have close to stock alignment when you are lowered an inch or more, you need front upper control arms and a rear camber kit. I've read a couple threads that state it is more than highly recommended to get new shocks. But when I message a couple of the Instagram famous Z owners or talk to local people in person, they literally only have springs (either swift or ark). That's it. Nothing else except for spacers. Can someone pleeeeeeeeeeeeease clear this up, can I just get springs in the meantime until I get my other suspension components? I go to canyons every Sunday and partake in some spirited driving lol. I just wanna lower my car but not **** up how my car handles. Most likely gonna shoot for the ARK-GTS. I am a college student so I don't have money to blow over a grand just to lower my car. Thanks!
