If I buy a 2007-2010 Shelby GT500 Shock, Strut, and Spring combo, will I need to buy GT500 eibach sportlines, or GT eibach sportlines?

Also will the 2013-2014 suspension work on my 2006 mustang gt?

If I decide to not buy shocks/struts/springs, will adding eibach sportlines to my stock struts and shocks give me a harsh ride or will it be fine?

My goal is to lower my car and get handling out of it on a budget. I don't wanna spend $1,000+ for a suspension setup.

I don't 100% understand the question. If you're just looking to run the GT500 Strut mounts, you can still purchase the GT Springs. However, if you're looking to run a full GT500 Suspension that is a different question.
