Hi M5 board, I am in need of some tips to correct an issue I cannot identify right away and it is progressively getting worse. I daily drive my M5 and
over a span of about a week I noticed a slight pull to the right when driving straight- and I mean slight- and the alignment was perfect in the past. I also at this same time noticed when looking at the rear of the car, the drivers side would sit about an inch lower than the passenger side visually measuring. The only changes I can figure that started this was a new rear tire on the passenger side with more tread, but not an inch difference since I run 275-30/19's in the rears.
The pull then became much more pronounced and the front right(passenger) tire is starting to detread in the middle of the tire as I can see crack marks showing now. Also, the left rear inside lip of the tire is now shot and a bubble has formed on that inside lip. I had a local indy check it out and they stated it was a rear shock mount. I changed the mount out myself with these AWESOME diy's on the forums(thanks!!) and it STILL sits odd after the change on the drivers side. An alignment and new tires are obviously in order, but can anyone chime in as to what the cause and at this point a possible fix?
I do run FK adjustable coilovers so I can easily adjust and corner balance to get it right, but I wanted to know if anyone else has run into this same issue or if this is just a case of an alignment gone very horribly wrong? I did not hit any potholes or curbs so no collision has taken place at all, it just seemed to happen during a 5 day period. All my bushings and arms look good in the rear since I was real up close and personal during the rear shock mount swap.
Any ideas is greatly appreciated to figure this out before I order the new tires and alignment to be done.
Thanks in advance!
