Need some help guys!
So about a month back I purchased some new suspension for my ZHP. I went for the BC racing coil overs. Was looking for a sportier driving experience that was still tolerable as a daily set up.
Long story short lately I've been hearing some funny clunking noises coming from the rear driver side underneath the car. I thought it had something to do with the coils themselves at first, but quickly found out what it is after doing some research... I now have a subframe that is starting to split, from the bottom driver side of the car, just to the left of the diff (where it normally starts).
BMW North America will not cover any subframe damage, as they closed out their lawsuit they had against them a few years back. Which is B.S. If you ask me. ITS A DESIGN FLAW.
I put the same post on the ZHP Owners Club facebook page, but I figured here would be a better place to hear some better input.

Any input is greatly appreciated.. :facepalm

Active Autowerke has subframe reinforcements to fix this issue. Also see Wyatt's build, he had this issue. I plan to reinforce my subframe before installing coilovers. Good luck with your repairs.

Mageec, did you replace the RSM when you did your suspension refresh?
