I am sure each setup will act differently when going down the road.... since most of the setups are not going to be installed and setup exactly the same, a person will get the same setup driving differently when going down the road.
Mine runs solid down the road with no issues. I have had mine up to 80mph (GPS real speed), for a few miles with, no problems. Usuallly keep it around 60-65mph just because of the high rpms. I drive it too work a couple of days a week.
I am running a 1.6 16v, 4.30 r&p(just swapped from 5.12) , on 31" tires with YJ missing links front and rear.
No sway bars and no panhard bars.... no issues
Kinda a balance between being a good driver on the street and good off-road.
