To get the bike turning quickly you need the wheel almost touching the ground but you might find it a bit twitchy and unstable and also run into problems like i had with the top of your helmet getting in the way of your vision! It really does lift the back of the bike a lot. 20mm is the ultra stable conservative setting.
I think its only in the last couple of years that the ST4S has had the revised top fairing.
