So, got the rears installed on Friday. Didn't do fronts because we didn't have time to get an alignment and have a LOT going on this weekend. Adjusted them to 1/2 turn out from full stiff, which really sucks to do and I hope we don't need to constantly adjust them. Wife is autocrossing today, will let you know what her initial impressions are.
As you can see, the only meaningful difference between these and the stock units is the threading on the end of the shaft. Removing/reinstalling the rears took 2.5 minutes per side, the time consuming part (though still, 5-10 min max) is getting the car jacked up and wheels removed, and transferring the strut mount/bumpstop to the new unit.
