The Steeda springs have a lifetime warranty and lowers the sedan 1 inch in the front and .8 inches in the rear to lower the center of gravity, and improve overall vehicle appearance.
The Ford Racing springs lower the car Lowers vehicle approximately 0.3 - 0.6 inches.
Here is a review on our springs
I installed the Steeda Springs on my car about two weeks ago and all I have to say is this is the way the car should have come from the factory. The car has loosed the rear end rake from the factory springs and over all is about an inch lower. Also with the Steeda rear sway thats on my car there is basically no understeer to be found where ever you point the car it goes.
If you are going to lower the car do it once, get these springs!
If I can help provide forum pricing then don't hesitate to email me at tim @steeda.com.
I look forward to hearing from you.
