Coil Overs What do i avoid??

Well everyone this is my first post for my car which i will be getting soon. I have been researching alot on different suspension set ups and i believe the best thing for my would be coilovers so that i will be able to adjust them when winter comes along.(line in ablerta so i have to be at stock height or i will hit snow all the time) I was looking at some coil overs called DropZone which came with the struts and the coilovers i was just wondering if any one has had an experience with these or if anyone has herd if they are goodor if you have a better sugestion i would be glad to hear it. btw i don't want to spend a large amount as i am already spending alot on the stg2 turbo kit. thanks for your time
