E46 turret reinforcement plates

It's not something we have done before, as I've never seen it happen. I pressume your talking about the fronts? What E46 do you have? The M3's come with a strut bar that's supposed to stop this from happening.
 
I've got a 2001 330i Touring. From what Ive been reading it seems a sensible precaution when running coilovers, might as well chuck them on at the same time as the coilies. Front for sure but I think they are available for the rear as well, I believe they are part of the 'heavy duty' option. Im think I read that M3s come with them as standard.
 
BMW part number 51717036781 for the front. Not sure about the rear though, cant find any info about them right now.

I guess I can go get them myself from BMW but if you do them then its less hassle.:D If its going to be grief for you though dont worry about it.:)

The E36 M3 3.2 had reinforcement plates, and I know the topmounts can be swapped between e36 and e46.

I've seen a couple of "mushrooms", they don't seem to be very common, but they do have issues every now and again.
