ESC recommendations PLS (non-MMM)

The mm is your best bet at the moment. I have good success with it and 7xl motors. Just make sure that you gear for around 40mph, and you may want to use a fan on the mm. I am guessing that you are making your own motor mount, as not much exists for the tmaxx. I have done a few tmaxx conversions, and found that the rcm revo mount works well.

Keep in mind that you will need to disable the internal bec in the mm as it will heat up too much on 4s. The Castle bec is a good choice for an external bec and can also be programmed if you buy the castle link.
