So to make a long story short I will be getting a credit from Essex Distribution for a set of H&R springs I had ordered from my previous car. With that being said I have figured to go with either of the following two H&R springs for my 2011 GT. If anyone can give me some details or info regarding them it would be appreciated, even if you don't have H&R springs some help with things to expect when lowering with the the difference springs. Thanks.
