Sorry to hear about the issues. I would have seriously lit into Turner for that little blunder. Maybe you can still manage to sell that E92 bumper?
I'm also in the situation you're in RE: front strut mounts and decreasing ride height\bottoming. I had ordered the parts to do the job myself from ECS, but the more I think of it, the less I want to spend a good chunk of my xmas vacation wrestling with it in the cold wet garage, so I may farm it out. I'm shamed, but also 60 is creeping up on me...
Thanks for the tip on the E36 M3 bump stops, I'll def pick up a set prior to having it done. I had installed Koni sports within the first couple K of buying the car and I'm at about ~70K right now, so debating whether I should replace them at the same time or not...
Thanks for the post!
