I got a pair of new burton cartels.
My front leg has a 24degree stance angle. I am adjusting the highback of my front binding to make it become parallel to the board edge. But the highback is manufactured to a shape that it is parallel to the binding.
Should I use brutal force to make a 24degree shift and slightly change its shape?
but then the center of the high back (where the + - sign is) is 1cm above the rack even if I pushed it down it just recoils back up
What do you mean it "is manufactured to a shape that it is parallel to the binding"? You can rotate the highback, so that it is not parallel/perpendicular (depending on how you look at it) to the binding by loosening the two screws were the highback attached to the baseplate (check the manual).
