What Inge said, and not so much the commentary from people who think bone stock is perfect and pooh pooh anyone who wants different.

As in any application where you're dealing with coil overs they are adjustable so the driver can tune them to their preference. I also agree with starting them dialed out so they offer the most amount of dampening, then take them in until you feel they're just right. Which is usually found by when they get too harsh and backing them off a bit.

Also it's handy to make note of the adjustments on them, either by measuring distance with calipers or counting full turns, etc. I know some guys who will have a daily driving setting on their coil overs, but then stiffen them up for more vigorous track days. That is part of the benefit of the adjustable shocks.
