sooo I've put about 90 miles on the setup and the rear end is still almost 2 inches higher than the front end. will it settle at some point or should i get some spacers from toytec?
Give it time. Unless you didn't touch the front at all? If the front is still saggy and you only did the rear, yeah it's going to stay higher because the coils are new compared to old, compressed ones up front. If you did both, you might want to check that the front is not over torqued. The rear coils will come down after a bit though.
I put 99 talls on my '98 about 2 years/10k miles ago. At first it looked like I'd forgotten to lift the front end, but after about 5k miles it settled down to normal.
These days though, it's starting to sag (again) when I put 100-200lbs of gear in the back. Initially 200lbs would level it out.
