We've just purchased a 2013 XKR-S in California, which I'm having shipped home to Oregon, stunning car! We have some quite rough roads here and although I don't mind the ride, I promised my better half that I'd look into softening the suspension somewhat. I'm guessing that I could replace (at least temporarily) the springs and/or dampers with ones from another model, like the same generation XK, or an aftermarket option. Is anyone familiar with the spring specs or looked into swapping them? Who should I talk to?
