I read the forum about suspension springs with great interest. I also want to lower my 2012 GT and was looking at 2 types. The Eibach Sportlines which say they lower the front 1.4 inches and the rear 1.5 inches. The Eibach Pro-Kit says it lowers the front 1 inch and the rear 1.5 inches. It seems the Pro-Kits would level the car more but want to hear from others that might have this set up. Thanks to all for your help.
