@jjvw (and others). I know this thread and the other one like it has been all over the place. And unfortunately I think some people have been misunderstood and in defense of their understanding of things, the threads have often gone off track into argueing instead of actually being helpful. As Mr Blaine mentioned above, I think most of us are here to learn how things work as we are trying to gain more knowledge and a better understanding for our own Jeeps. We are not 'fan bois' of any specific builder, but instead we respect all the different builders that have shared knowledge and even products with the Jeep community.
I am here because, although my Jeep handles well, I can feel that the geometry is not as well setup as it could be. Particularily at high speed. So things like Daves geometry correction brackets have appeal to me, as they appear to solve the problems I have (or think I have) at a lower cost than a full rebuild with midarms. But I am very heistant to change any geometry without doing my research. Even then, I am forced to hire out the work because I am not a welder or fabricator. So gaining a firm understanding of some basic concepts is very helpful since it is unlikely I will be able to take my Jeep out to the west coast to have one of the better known guys do the work for me and there is not a knowledgeable 4x4 shop in the area that I am aware of. So I for one greatly appreciate all the effort and time that folks like you and Mr Blaine and Dave have put into helping us understand what certain products do and don't do.
So to get to my question. I think I have a grasp on what you are saying in regards to short arm vs geometry brackets vs mid arm. But for clarity please let me know if I understand you correctly.
My basic understanding is that the factory short arms are going to be fine for most people until around 4" of lift. At which point some sort of geometry correction is needed. At this point it seems that for the serious offroader, the Savvy Mid Arm solution is likely the best designed and most complete solution available. However, there are two instances where things are muddy for me and I don't understand the best solution.
1) My first point of confusion is at highway driving. I live in the flat lands of ND and I drive my Jeep at 80 mph 1000 miles each way to Colorado every couple of years to do trail riding. So my needs are obviously different than others. How would you compare your mid arms performance in a high speed emergency lane menever to a similarly lifted TJ with stock arm locations but maybe a raised rear trackbar bracket. How do you think geometry brackets would compare in Interstate driving. I get the impression from comments above that the Savvy mid arm is stable at interstate speeds, but I would still love to hear your opinion.
2) Is it your opinion that geometry brackets provide no value and do not work, or is it only that for the amount of effort it takes to install them you are better off going all the way to a mid arm setup?
