I may have to take out the b-pillar trim but I don't want to leave it out permanently at the moment. I have no problem trimming it, but Mark at Kirk Racing told me it should slide past. What I'm thinking is the bar was designed for an S4 model. Those don't have the automatic seatbelts so the a- and p-pillar trim is a little narrower. I didn't want to have to totally gut the interior for this...
