I have been running Steeda Sport Springs for about a year, I didn't change out the shocks and struts, just the springs. It was ok for a while, but my 66K mile shocks and struts made it become bouncy and it rode like crap.
I ordered the Bullitt Suspension Package from
www.stangsuspension.com. It includes the Ford Racing C Springs, the Bullitt front and rear Sway Bars, and the Tokico Shocks and Struts, this is the original Bullitt Suspension. It cost $415 total.
Just the Tokico shocks and struts were $299, so I decided to order the whole package, maybe sell the springs.
I originally installed the sway bars and rear shocks, it rode loads better, but I ran out of time and didn't put the struts on. I decided to go ahead and install the springs too, so yesterday I was under my car all day long, I installed the front struts and springs and the rear springs. The car rides and handles better than I ever remember it, and we bought it with 8400 miles on it back in 98. Kept my cool low stance but with a smooth but firm ride.
My wife had ridden in it about a month ago, said it rode like a ghetto car and she didn't ever want to drive it again. Today she drove it, it drives just like my son's 03 GT which has 30K miles and has the stock suspension. She was really impressed. I haven't aligned the front end yet, that comes tomorrow, and I am getting new Nitto NT 555's this week.
