2003/04 Cobra front springs November 03, 2019, 08:32:08 AM I see that in a lot of posts that when you guys upgrade to newer front springs that you use 99 up Mustang GT springs. I have 2 sets of 2003 Cobra springs that I swapped from a coupe years ago. I think they are 300lb rated springs or something like that. Will these lower my bird plus keep the front stiff? I know my Cobra was not so comfy of a ride but that was not the purpose of owning a Terminator.
