This photo was taken when I first installed my Euro Armrest (larger, flip-open' by pressing MINI Logo)
and it also sloped down towards the gearshift handle (I assume for tall stick-shift drivers comfort).

You can see a 'hard-rubber' Wine Cork taped to hang in the hinge area.
This 'shimmed' the armrest up to the level I preferred and it still does not interfere with my auto-gear-selector
and gains space for a tissue box above handbrake.
As soon as I was happy with the angle, I 'contact cemented' the 'cork' to the backside of the armrest where it can no longer be seen.
The resiliency of the shim gives a nice 'springy' feel for this armrest, which is plenty large enough for two arms or elbows,
