I have an 08 GT and bought the Eibach Pro-Kit Springs. The dealership wants $400 to install them plus $68 for alignment. They said if I put the rear ones on myself it would save me about half for installing the front. I found one other place called Chassis Systems in my area that said they can do it for $220 WITH alignment. They said if I installed the rear ones myself it would save me $80. I'm not sure if they have lazer alignment or not, but is that really necessary? And, how difficult is it to install the front ones? Also, will I need anything else like camber adjuster plates? Any feedback will be greatly appreciated. Thanx
