I will really be surprised if changing to ANY shock/strut combination makes much difference in the ride harshness of this car. This is a no compromise car, it's designed to handle, not to compromise handling against ride, the springs, and swaybars have more to do with the ride harshness than the shocks.
My wife hates my Vette for the same reasons, but she knows I love it. I'm lucky enough that she loves me enough not to make me sell it.
