Darn good time since shop labor time is 1.3 hours just to replace the entire front strut assembly just for one side. Assume you also had to use a spring compressor to remove the original spring to replace it with a shorter spring. Replacing the rear spring only on one side is easier, shop labor time is just 0.6 hours.
Certainly been a lot of TSB's on the upper strut bearing, mainly for the 2011, seems like Chevy forgot to grease them, again.
With MacPherson front suspension, single control arm, with the car one inch lower, control arm will be one inch higher. Taking the pivot point of the control arm to a right angle to the center of the tire, that center point would be moved inward increasing the negative Camber, this can be calculated, or better yet measured.
Since the lower strut bolts are fixed, can also purchase offset ones to get your camber back to zero. For my Cruze, calculated with the throw of the control arm, get side movement of the front tires of up to half of an inch every time you hit a bump! Its no wonder the front tires don't last very long, but tell you to rotate them to even out the wear.
State recently repaved a road I use a lot, even added a bicycle lane, that's nice, have yet to see bikers use it. Then afterwards, decided to dig trenches to equalize the drainage on both sides of the road by adding culverts. This was stupid, now that brand new road has low spots every several hundred feet. There goes my tires.
In my neck of the woods, guys like to buy pickups and jack them up a couple of feet, don't want to take a corner a tad too fast, will roll over. But this also looks cool.
