Hi Bordia,
I agree they're definitely stronger than the E46 mount.
But there's some evidence that it may not be fully licked:
- Members MrBimmer, Xaeryan, onefastman and katsooba have reported mushrooming -- two from potholes, the others didn't explictly state what happened (Edit: Added reference to katsooba on 2013.05.07)
- I spoke to Dinan Service in Campbell (CA) and they've definitely seen this happen on both the E82 and E9x chassis - almost always after hitting a pothole or curb. Not to the level of causing cracks, 'just' an upward deformation which causes the studs to splay out a bit. The repair method is the wooden block & 3-lb hammer technique...
- I also spoke to BR Racing in Los Gatos (CA). They've raced a E82 and for track work they recommend reinforcement... with the Vorshlag plates as the way to go.
Hopefully I haven't come across as unduly alarmist, but I am trying to determine if some preventative reinforcment is worth doing (note that I typically track my cars 4-5 times per year).
Karl.
