Has anyone gone through the process of replacing the sport suspension components?

I picked up a 2005 3.0 Manual with sport package. I love the seats, shadow line, etc. but find the ride to be obnoxiously stiff on our lovely roads here in WI. With 120k, I figure the shocks are due replacement anyway so I am thinking about reverting to the 'non-sport' springs and stabilizer - that seems to be about it?
