X5M performance and handling mods?

[bcredliner]

Would like to hear from those that have done mods to their X5M. I am most interested in anything that improves 0-60 ET but I would also like to learn what you have done to improve handling and how you chose to lower the vehicle.

In January, I will start looking for a 2015-17 X5M.

I might end up buying a new one and pick it up at the plant. I think that would limit me to Dinan to keep the factory warranty so hearing from anyone that has gone the Dinan route would be great. If I buy used it will be one with less then 30,000 miles.

I would like to hear about HP/TQ gains and how far I can go before I have to worry about something breaking every time I launch it though I have not problem going to the iffy point.
