LilRoush Posted July 3, 2012 Report Share Posted July 3, 2012 For that first post, the 99-04 V6 and GT stock springs are different. There were basic 3 springs made (leaving out Cobra/Mach/Bullitt): GT coupe, GT vert and V6 Coupe. The V6 vert used GT coupe springs. If you put stock GT coupe springs in a V6 coupe, you'll lift the V6 up about 3/4"-1". (I know because I did that as Winter trick on my V6 while living in MN).

Black Brad Posted August 2, 2012 Report Share Posted August 2, 2012 What would be the best 1.75-2 inch lowering spring that will ride decent, sportlines or h&r super sports? How do spring rates affect the ride? I'm kinda looking for a 2 inch drop that has some kinda performance...seems like the super sport would be better.
