I'd like to know what you mean by using the jato gear. Clutch or spur? There's a bunch of different size gears you can pick up for the T Maxx. Setting up a T maxx for top end isn't the most useful thing to do to it. It may be fine on the pavement but you'll lose a ton of off road capability. If your set on trying to achieve more top end for the street, a good set of on road tires is a must. If the street is the only place you have to run, an on road vehicle is more up your alley.
