Tower has most parts, if you stripping the gears on the inside, the FOC will help because it takes out a lot of rotational mass. If your stripping spurs and clutch bells, Robinson Racing makes a great hardend steel package. As for motors, I would go with a .18 tm or TZ. And Fantom makes a great pipe, or the Traxxas resonator. I wouldn't bother with all the aluminum stuff, it bends or breaks easier than plastic, so if you ever want to upgrade plastic parts, see if RPM makes anything.
