I did the same thing on my bike.
Corbin seat with the oval back rests.

It is the widest I was able to find at the time. And my wife has a sensitive tuchy.
Rivco passenger floor boards with the extension arms, she has long legs, 5'9.
I did not upgrade the shocks because I did not notice any problem and am unsure what new shocks will do to the ride.
Do they make is a stiffer ride or softer?
