I replaced the Fronts with the 5100 Leveling shocks and I adjusted them to the setting 1 down from the highest. I replaced the rears with the 5100's as well, and yes, I did put in the T/C Diff drop. Rides the same as stock, and I took it for a pretty intense weekend 2 weeks ago, and had no issues. I will be posting a write up this week when I get some time, in the Billstein 5100 shock update thread. :tu:
