I had a 95 GT and when I lowered it with the Eibach springs/Tokico dampeners I had to put on the Steeda bumpster kit along with the X2 balljoints and assorted bushings to curb the problem. I plan to lower my 06 GT with Steeda springs and was wondering for those of you who have already lowered, did you have to use the bumpsteer kit on your new Mustang?

 

I used the Steeda springs but I never got to try it with JUST the springs because I put the bumpsteer, adjustable panhard bar, control arm relocation bracket, caster plates and LCA's on all at the same time. I love my Steeda suspension and it works just as well at the strip as it does on the road course.

 

I've done Steeda springs only so far, and it feels absolutely fine. My rear axle is only 1/8" off, so no panhard bar needed. Front needs camber bolts. I don't plan on doing much more. The stock dampers feel really good. I'm pretty picky about screwing anything up, and I am very pleased about it. The Steedas provide probably the smallest change from stock. I think the height is perfect...

Can't imagine you'd need the bumpsteer kit with the Steedas. Maybe with the Eibach Sportlines...
