Start in the middle, go for a drive and if it feels too soft at either end give it 2 clicks stiffer or if too hard 2 clicks softer and go for another drive.

Keep going until its how you want it.

Make a note of the set up.

Then you can back it off a bit for a wet set up or stiffen it up at the back if you are running 2 up.

There is no quick solution, thats why race teams spend so much time testing.

Worth the effort though.
