This is really shocking to me. RealOEM says you should've had rear bump stop PN 33536850537 with your car. Does this mean you also didn't have any dust shield/boot/cover around the top exposed part of the rear shocks?

I'm not sure if the B8s for the F3x have the same valving as the B6s, but it's definitely a probable reality given how lazy they were with tuning (they only have a few PNs across the entire F3x range vs tuning for each config). One thing I expect is different is the internal bump stops in the front strut. The B6 ones are pretty long, but soft, and I found that with Eibach springs I was already compressing it .5" at static ride height. I ended up trimming them by .5". The B8s probably have a shorter and stiffer internal bump stop.
