Tein lowering springs on 13 civic ex 2 door
 

Hey I have a 2013 civic coupe completely stock. I want to put lowering springs on my car but I need to know will I need to buy anything else to go with the springs( https://www.jhpusa.com/store/pc/viewPrd.asp?idproduct=24534&idcategory=157 ) I'm completely new to this. I also want to have a -2.0 camber on the rear and maybe -1.0 to -1.5 on the front. Will I need to buy a cambering kit?

Any advice is welcome!!
PLEASE HELP!
