I have an E30 325E 4 door, starting to consider prep for going to CR school. My first step will be to strip and cage it. Looking at the GCR, 9.4.B.1.a: "On all closed cars, the main hoop must be as close as possible to the roof and “B” pillars."

If I run the main hoop against the B pillars I will have to use a bent harness bar. I would much rather run the main hoop a few inches further back against the back of the rear of the rear passenger footwell, basically where the body goes vertical for the rear seat "platform." My reasoning for this is to keep the harness bar straight and in plane with the main hoop along it's entire length.

Question is, is it legal to run the main hoop a few inches rearward of the B pillars? I'd also shoot an email to a tech guru, if I knew who I should be emailing.

Thanks.
