Thanks for the thoughts. The latest order is for some carbon 'A' trees, so that should take care of breaking the diff cover (only happened once so far) when using the regular uprights I think. Kind of peeved as I lost one of my metal suspension balls in the last crash, kind of expensive vs. the A tree ball. I'll see how the carbon suspension mounts stand up to my driving, I dont want to spend a lot on aluminum mounts and then have them messed up. Of course not having 45mph crashes into fixed objects might help some too
