The 5-bolts mount was part of the LCI modifications to increase steering feel. This noise was fixed in the F3x by a new steering rack insert kit as discussed before. Nothing for the F8x other than replacing the rack.

I think the 5 bolt mounts were an attempt to fix this problem, but didn't completely eliminate it. I've driven another members 2017 car in my test bump and the noise is there but mine is significantly worse.

Now the tough question: how to fix it?
