    Lol I actually got a rivet spacing equation from an aircraft design book...I went with the minimum...

    ...And used massive headed rivets

    It's obnoxious, but uhhh pretty strong

    Glad the culprit was found, otherwise I'd feel real bad about derailing this thread.

I also did an aluminum plate tying the floor and rails all together. It was really just a convoluted way to get the same result as the vincebar but will still allow me to install the x brace.

    Wow, amazing. What's all that black stuff, POR15? Also, will you be writing it up? I'm fascinated with your approach to this problem. Did you have to do any welding?

    I have too many questions. lol

    My guess is structural adhesive, this man is building an airplane

    Yep, 3M panel bond. That's why I sanded all of the mating surfaces before install - that stuff bonds hard to unprepped surfaces so I'm sure it's in there for good now.

    I did no welding. The idea was based on Vince's epoxy kit, with a lot of design and fab on the fly as I went along. I'll try to post all this in my build thread so we can discuss it there instead of continuing the massive hijack here!

    Good news: RTABs took care of the creaking. Car rides great.

    Bad news: After an alignment, now have a DSC and Yellow Brake light illuminated. Was not on previous and car was never out of alignment. Did the alignment to make sure things were straight after the bushings. Drove it about 20 miles, tried taking the steering wheel lock to lock, nothing. So, back to the shop itíll go.

    I wonder if it is the steering angle sensor requiring calibration. During my DIY alignment woes, that was something that I came across during my research

    That was my thought too. I decided to order the Foxwell NT510 from amazon. I figure I need an OBD reader anyway and this will cost only a bit more than taking it to the shop for diagnosis.

    And for what must be a first in BMW history, the light turned itself off this morning....go figure.

    lol probably the steering angle sensor. The foxwell should be able to pull/clear it.
