I went with the RTR springs on this 24 GT non- PP. Rides great handles awesome. One inch drop in front 0.8 ish in the rear. That photo was right after i put the springs on. springs have settled and sits a bit lower now. has 19 inch rims with factory tires.
Driving under the speed limit in a mustang for sure suspicious. They figured you had something to hide, probably looking for a good chase that you did not give them.
The first photo at the top looks like it isn't seated right obviously. but then again it doesn't look like it is in a bind either. IMO if it is not giving you trouble or making noise i would roll with it. I wish I had photos of mine but i dont to share with you.
I just installed the RTR tactical lower springs on my 24 GT. I could be wrong but something looks off. I dont remember my springs being that close when installed.
