CATS /SuperSport suspension on XKR worthwhile?

[notax]

As you may have seen on earlier thread, I am after a secondhand XKR. Is it worth looking out for cars with the above? I like firmly sprung cars but not sure what the above consist of? Is SuperSport a version of CATS or something different...

Thanks - I found a 1997 car which mentioned supersport suspension - and looks a lot lower in the photos. However, now after a newer car to avoid the various engine issues - but sadly my budget won't stretch to the limited editions you mention. Just have to hope I get lucky, but at least it will have CATS from what you both say.
