Well, I finally broke down and did it.
I installed a set of lowering springs on the GT this weekend. To be
honest, I had not done a set of 05+ springs yet. I have done
multiple springs on a lot of other vehicles but none have been this
easy. I went with the Steeda Sport Springs. The installation went
great and the drive is even better. I must say that the car still
rides as smooth as factory and handles much better. No more nose dive
or hard leaning during turns. I would highly recommend these springs
to anyone. You can install them in under 2 ½ hours with no
more than few hand tools, jack stand and good jack.
