On mine tweaking them up a couple of clicks at a time then driving on a similar stretch of road I found a point where the front stopped moving up and down so much. For the first few hundred yards it seemed the suspension had become too firm but then after a mile or two I realised the ride was actually more comfortable because of such. I called it the sweet spot as it was so well defined. You can always back off a click or two to prove the point.
YMMV
