RTAB pocket reinforcement?

[fanchazstic]

I've seen a lot of discussions about this pertaining to e46's, but in my searching haven't found anyone talking about it on our chassis. I'm going to be doing a TON of suspension work on my car and I'm trying to put in all the reinforcements that I can to help prolong the life of the car. It already has 140k miles on the odometer and I plan to drive it for plenty more. Is the RTAB pocket as much of an issue on the Z4's? I know for example the subframe mounting points that are an issue on e46's aren't an issue on the z's because the subframe mounts to the frame rails, but I haven't found any discussions about RTAB pockets. Any info/opinions are appreciated or if there are existing threads that I missed in my search, please link them so I can read through them
