I just installed a 22mm swaybar and it's not that straight forward. The convertible has an additional rear subframe bolt (5 total) in the middle of the subframe, right above the exhaust pipe.

I had to remove the cross brace (center only, you can swing the arms out) then i proceeded to drop the exhaust with a jack underneath it and remove the heat shield enough to reach center bolt.

In all a little more work than expected but the results were worth it.

First ride was great but seem to soften a little after a few runs. Has this happen to anyone else with rear swaybar install?
