The geometry correction here in and of itself is interesting where it addresses roll center and potentially the antisquat. Potentially. I know what I was seeing, so I'm not on board yet. The rest comes across as a lot of uneeded hyperbole for the sake of a bolstering a sales pitch.
Why a mid arm? Because when you actually need to address geometry problems, then solve them. Before that, I am a firm believer that for most people there is more immediate and over-arching benefit from good shocks and sway bars. Both of which can overshadow the minor issues most around here might face from lifted short arm geometry.
In my case, the every day driving and general off road didn't change a whole lot after the Savvy mid arm. And no, there is nothing unstable about it. That is absolute hyperbole. Right now mine can easily do 75mph with two fingers on the wheel for hours on end and has the ability to make hard right turns that squeal the tires with one hand on the wheel. What I notice most often is an overall calmness and predictability in the way mine moves through an obstacle. There are no bad habits with the Savvy mid arm. But where we are and what we do, we are all getting through the same trails.
The three most dramatic changes happened after the mid arm. The rear outboard with a good tune, followed by the Swayloc, and finally the front shocks with an improved retune on all four corners. The Swayloc made street driving nicer. But the shocks did more to transform the Jeep for the better in most scenarios than anything else did. This is why I downplay geometry correction as a point of fixation, because mine has extremely good geometry correction that comes from a winning race team. And despite that pedigree, if I were to do it all over again, I would start with shocks long before any geometry correction.
