Cheers for the replies,
In response to what has changed, From standard the body roll has decreased a lot... Through corners, the car feels more nimble, less like a large whale, more like a nimble seal...
It it still a heavy car and you can feel the weight, but it seems to be more distributed and balanced.
Im not sure how much the springs have made a difference handling wise, but the package together has transformed the cars feel.
Needless to say it feels alot more confident through the corners.
I am yet to test it to the extreme, but a track day may be on the cards in the next few months.
Jamie.
