Unfortunately, Anything to increase front travel is going to cost some bucks.
I just went over the entire thread again to see what arms your using. As far as I can tell, your using the stock EB arms? Not sure if you extended them and by how much if you did. I would consider going longer to help increase the travel and thus helping the "Feeling" of high COG with off camber stuff.
I def wouldn't use the 3.5" coils.
Someday you will be installing hoops and long travel coil over shocks. These seem to be the best option for the most articulation possible. Check out BKennedy's, Ricks, & Turboexplorer's builds. They all run the coilovers/SOA, and they all have mad travel, and no complaints about off camber situations for the most part. Rick installed the anti-wrap bar set up.
Someone here would buy your JD stuff if you ever change it up.
Oh... The more you use it, the more you will want out of it. This trend will take a stock Explorer, and eventually turn it into something that nobody even knows what it was to begin with. In other words, it never ends, until you seek professional help, or the wife threatens to leave you over it.
