getting rid of the rear air?

[X5X35D]

so i put h&r vtf and i'm super happy with the look and the way the front feels and drives but the rear is just too bouncy.
i wanna keep it low, don't mind the hardness but i can't deal with the bouncing. i assume it bounces because the air bags are squished all the way down and it's like the whole rear end sits on rubber blocks.
i was thinking maybe leave the front as it is with the vtfs and work something out on the rear end only.
what are my options?

update:
the lowering links at the rear were turned all the way down and there was no air going into the bags. after 2 turns up on the treads everything came together perfect.
now the ride quality is proper.
car is 2.5inches down and comfort mode feels like sport+

i'm very happy with the results
