Depending whether you will be racing and what type. The kit tires are fine for outdoors but not the best for carpet. If you think you will be buying the upgrades in the FT version, you will save money now by buying the FT versus the Team.
I work with new racers at our club, which is a carpet track. If you plan to race and haven't done it before, I would recommend against buying a modified motor first. I don't know what your skill level is or your racing experience/background. I always recommend to new racers that they start with a stock motor.
If you're set on a 12t, then I also recommend buying a Novak or LRP speed control versus the Duratrax. These are higher quality for not much more money.
Tell me more about what you plan to do withe car (race, bash, etc.)
