Has anyone done air bags to a XR6T BF Series 2? I also have heard that in some states even if you have a engineering certificate they will not pass your car roadworthy... I have also heard that it ruins the handling and makes the car massively airy on the road? I was keen as to do it but those 2 factors were a bit of a turn off...' I looked at price aswell, looking at about 7-9K fully done.
