Honestly, if I had it to do over again. I would just stick with the racer kit. You put that car in the hands of even a good driver, and they will go just as fast as a FT kit. It now comes with an aluminum driveshaft and you wouldn't believe how many drivers run composite CVD's anyway. The one real gain I see you get in the FT kit are the gorgeous threaded aluminum shocks. So I would get a racer kit and slap a set of Tamiya TRF shocks on it and be done with it.
If you feel like spending money for the FT kit, go for it. It sure is pretty.
