update to my BK seat mounts

I ended up fabricating my own low profile sub-strap bar.
I now have my seat sitting all the way down to the ledge.

Bar is 2" x .25" 304 SS; fasteners are all 10.9
All holes are through BK mounts only, the OE rails are untouched.

Pic also shows the PnP wiring harness that I made up.
OE seats and wiring are 100% untouched.

Autocoutur have found away to mount the BK sub strap bar it what looks like a perfect way.

They drilled the mounting hole to enlarge it enough for the sub strap bolt and is using the bolt for both, the bracket mounting point and the holding the bar in place. Because it sits before the seat sink to the lowest point, it works.

Looks like it will work nicely.

I considered that approach as well, the thing that held me back was drilling out the hole on the OE rail would make it hard to go back to stock.
The OE seat bolt head is indexed in place so the the seat will raise & lower without binding.

Anybody having a problem with airbag lights? I made the mistake of removing OE seat without disconnecting the battery. I installed the BK mount with a recaro PP (drivers side only) and plugged the OE seat belt receiver plugged into the harness plug coming out of the floor. When i turned on the ignition I got the airbag warning on the cluster and have codes 93AC MRS:seat airbag left, and 93AE MRS: active head restraint. I tried to clear with a foxwell nt510 but no success. Keep in mind I am using a manual OEM slider and my car is equipped with power seats. Not sure if that would cause a problem.
Also, if anybody is interested I have a 2 R9281 mounts for sale, both new, only removed from the packaging to verify fit, with all hardware. I also have an new OEM e30 window switch.

You can't just clear the codes, you will have to code them out. If you know how to code, here's a thread on the specifics of what to code out.

Otherwise you can pay somebody to code it out for you, but it's a bit expensive for what it is imo.

Has anyone weighed the total BK mount + motor/E30 switch assembly compared to the typical floor mount + brackets that the typical race seat setups use? I swear I saw some numbers about this earlier but I can't find them now... :/
