Mine is Aluminum, currently I am lowered 2" in the front with Belltech struts, rides great, no alignment issues, the only time i get a bit of a rub is in reverse at full lock, and its just rubbing on my mud flaps so not too concerned i should really find some new ones since these sit an inch off the ground now that its lowered haha.
If you are looking to drop 2" or less the struts are a great option imo, I kind of want to go a little lower now I have been considering some DJM 2" control arms and going back up a little with the shocks for around 3-3.5" total in the front and then I would drop the back from 5 to 6. Decisions..
