2011 RS SM.
This is how I did mine:
Frunk off (I was doing the fog light installation too.) Removing the frunk makes it so much easier to access the top bolts....there's only an electrical connection on each side and four bolts top and two at the bottom....five minutes and the frunk is off...!!!
I removed the nuts on the top and bottom complete...the bolts will not drop out...the shock is still loaded.
With a jack under the center frame, just take the weight of the machine...you can gauge that by trying to rotate the front tyre.
When the tyre just breaks free of the floor, both bolts will come out just fine. Further elevate the frame by about 2" and you can work the shock out.
Work in the new shock, locate the bottom outer end and slip in the bolt from front to back and start the nut on the end.
My jack has a nice pressure release screw so it's easy to control the rate of descent, so start to go down and control the rate so that by guiding the top with one hand and looking at the attachment bolt hole you can stop the jack right on target and the top bolt will slip in from rear to front. If you miss, stop the descent, give a short pump up and go again.
Tighten top and bottom bolts to specs and do the same on the other side.
This was my first time doing this and I was done in thirty minutes.
