Glad I helped. My goal was to answer the question while trying to explain some of the heat from others.
Just remember you've got a Wrangler, not a Mustang, 350Z, etc. Generally, your best approach with any mod plan is going to be to make the vehicle better at what it was meant to do. And more so than ANY commercially available vehicle in the US, Wranglers are meant to go offroad over rugged terrain. So you'll have your best results modding toward that end. From a design standpoint, road handling, speed, etc. are secondary. The consequences of all the offroad appointments (solid axles, true 4wd, big tires, etc.) is that Wranglers handle poorly at high speeds.
It's the same reason you don't see a lot of folks turning Mustangs into overland vehicles. The platform isn't a good starting point. Absent significant changes, the Wrangler platform just isn't a good one to begin a "street speed" project.
