Lock rear dif, fit drift tires, and PRACTICE.
Front spool diff will help marginally. Stay away from steering and drive train mods to start with, does not add anything on a TT-01.
Oh, and either go back to brushed (you don't need heaps of power, it will only break parts) like a Carson Cup Machine, or use a SENSORED brushless. Sensorless is quite jibbery on pick-up of power, while you want smooth pick-up.
