Newbie here, looking to lower my ride

They do have lowering springs that lower your car but you cannot adjust them. And the struts/shocks aren't built for the springs so they will get worn faster. I went with adjustable coil overs and felt I made the right decision. Up to you on what you want to do.

You can but make sure you get it aligned after install. I lowered mine with the Eibach kit then waited over 1 1/2 years to replace the struts and shocks. No need to waste money if they are working as advertised.
