Driver’s sport seat bottom has 19 degrees of rear tilt in the lowest setting. I am unable to flatten seat bottom causing Sciatica nerve pain which causes my legs to fall asleep while driving. I have owned several BMWs with sport seats and this is the first one that has caused problems. Base sport seat needs more adjust to lower degree of rear facing tilt.
