E92 - Schroth Quickfit Pro Install
With 370 posts on the other thread, I thought I would add a simple install guide with pics. It took me about 30 minutes.
1. Buy the mini harnesses - HMS were very prompt
2. Tools: Torx T50 socket; torque wrench for 30 ft pounds; a vice with pliers for bending the Schroth brackets
3. Front: Pop the rubber cover off the Torx bolt at the front of the seatbelt rail
4. Undo the T50 bolt
5. Determine how much you want to bend and twist the Schroth bracket. Do it. I tried to get the angle and twist so that it aligned with the direction the belt would pull.
6. Tighten the T50 bolt to 30 ft pounds
7. Trim the rubber boot so that it fits back over the T50 both with the Schroth bracket
8. Rear: Remove the seat cushion - pull up, some effort is required
9. Undo the T50 bolt
10. Determine how much you want to bend and twist the Schroth bracket. Do it. I tried to get the angle and twist so that it aligned with the direction the belt would pull.
11. Tighten the T50 bolt to 30 ft pounds. I did not use the 13mm nut an washers provided by Schroth, because the factory T50 bolt fits just fine
12. Reinstall the seat cushion
