Hey Ryan.
If you can save up to an M135i, there are other options out there that may suit your need. For example, tuning/look/drive/whatever. If you must have a BMW, then that's alright too. BMW parts are expensive, that's definitely one of my concerns, but just fyi.
Other than the possibility of your voiding warranty, lifetime for your parts are shortened. There is more wear, gearbox has their own torque ratings, so I wouldn't do anything too aggressive.
I personally recommend leaving these heavily computerized cars along. Mine is fully stock 'cause I think I got enough power already. For my case Kart driving and track driving definitely improved my driving somewhat, and that improves the speed of the car overall.
Just my 2 cents.
