Right, quick update - I just went out for an hour on the hardest setting on all 4 corners and from what I can tell so far I am really pleased. As you would expect you feel every bump in the road even more than normal, but I don't mind that as the car isn't my daily and I like that connected-to-the-road feeling. Going round roundabouts and cornering there is little to no body roll and the car feels extremely planted. I wasn't pushing crazy hard as it was dark and I am still getting used to the car (and it hasn't had the break-in service yet), but I love how it feels
I forgot to mention the car's ride height has been dropped by 25mm all round when it was installed.
