Hey guys I have an 04 Gt and want to get it lowered...What do you recomend? And what is the total cost (around).

 

eibach pro kit(1-2") and the eibach sportline(2-2.5") and its about simple as cake to do it yourself. there are many writeups on it. it only took me 45 mins to do mines and about the same to do my g/f's v6. i belive the springs were 200ish. i cant remember its been awhile. check americanmuscle.com

 

you also have to get an alignment when ur done

 

I have H&R racing spring, I bought them more for handling than a drop. The droped a lil nothing, H&R also makes different drop springs that are pretty good quality.

 

If you just want to lower the car for looks then I would get the best brand name springs you can afford.Eibach,Steeda,and Maximum Motorsports all have good quality parts.Now for the caveat,lowering your car can make for funny if not dangerous handling characteristics.I suggest doing lots of research befroe you plunk down your money.Here's a link to get you started.
