I have had their +2" Race Kit since 2015 (which has since evolved into their expedition Kit) and I love it. It allows quite a bit more clearance under the arms compared to their standard kit (as Inv4drZm mentioned).
I didn't want to run fiberglass so I felt the +2" kit was perfect. It allows me to run 255/80/17's with a body lift and no rubbing. Also, with a pair of spidertrax in the rear your track width is so similar you don't notice the difference.
The rig definitely isn't as stable on the highways with no sway bar and softer springs. Total Chaos does now have a +2" LT sway bar that I am looking to add.
What exactly are you looking at the kit for? It is definitely overkill for most peoples purposes. Also, anything specifically you are interested in knowing? It is worth mentioning that this is not my daily driver and if it was I wouldn't recommend long travel.
Here are a few photos from a trip to Death Valley a few weeks ago. Most people wouldn't be able to spot its a long travel rig, but you really notice a difference in what it handles when it hits the dirt. Safe to say I cruised through things at a different speed and comfort level compared to the other 4th gens I was with.
