I have a 2018 X3 XRS 2 seater, I'm trying to adjust the suspension so it's a little more comfortable when going through the choppy stuff at slower speeds. I've completely softened high and low speed dampening, front and rear. I adjusted the rear crossover up about an inch. It still rattles our teeth. Should I adjust the rebound? Any help will be appreciated or point me in the right direction please, thanks.
