Time for another lengthy update.
I was able to get with the local guy (07 Chevy on GMFS) who I bought the drop kit from and we got the drop installed.
Up front I went with spindles, 2" springs, and struts set to 1. While we were installing everything we checked out the rest of the front end parts. Everything seemed good except the lower ball joints which are worse than my uppers were. They will be next on the list.
Out back, we did the flip kit to get 7". We left out the bumpstops since there was very little clearance anyways. I accidentally left the overload leafs at home (I always forget something) so they did not get put on. Once I make sure I'm at the height I want I'll take the time to put them back in. I also left the hitch off temporarily. His shop has a pretty big dip at the entrance, so we had to take it completely off to get the truck out.
The ride home wasn't awful, but it wasn't really pleasant either. The front rubbed a ton and the rear bottomed out constantly under normal driving conditions. As seen in the last pic, the front has some pretty excessive negative camber at the moment. I believe that is the main reason for rubbing up front. It's getting aligned after work today, so I'll know more then.
I think the bottoming out is worse at the moment due to all of the parts and my 22 in the bed. Here's the current clearance for the rear.
Once I get it aligned I'll know more and be able to take actual measurements, but the rear seems like its closer to 8" than 7" how it sits.
