I have one on my 2015 edge v6 can’t say it does much but tbh sounds cool

I need new rotors and pads in the rear. I am just going to replace all of them. I cannot for the life of me figure this out I see powerstop sells a kit of all four with rotors and pads but it won’t tell me a size 13 inch or 14? Also they said I need shocks and struts…?? Anyone have any recommendations for a better upgrade than OEM? 2015 Ford edge awd titanium v6 3.5L 71k
