ORIGINAL: get sideways
Tt-01 is a good chassi for the price... I've had three and loved all three. Don't lock both diffs, just the rear. The only negative thing I have to say about tt-01s is that they have a govenor... No matter how low turn of a motor you get, the car will go the same speed. (Even if you do brushless) the motor will wind out, but the car will stay at a certain speed. Its not a speed chassi, but it sure is hell is a great drifting chassi! Good luck w/ the driftin!!
its mostly for torque because they use this chassis for rallying. You will need a proven race chassis to get high speeds like a tc4, t2, xxx-s, mr4tc, sprint 2, and such.
