Monroe struts and lowered springs
 

I just replaced the OE struts and springs with monroe strut assemblies. The car rides very comfortably compared to before, however it sits way too high and the look is not as aesthetic as I'd like. Is it possible to simply swap the monroe assembly springs with eibach springs? Or should i just save up for set of coilovers?

You can definitely swap out the springs. Make sure you have the springs compressed (using a spring compressor that can be rented for free from autozone) before you remove the top strut mount. If you try to remove that mount before compressing the springs, it will get shot off from the tension releasing from the spring and maim/kill you, no joke, people have been killed this way. Also you sorta need an impact gun. You can definitely do the job without it but have fun spending an hour trying to compress your springs by hand.

Is it possible that the car will settle and lower itself after awhile?

Let's see it
