It is a better car because the fuel tank was finally moved to the center, which makes the center of gravity even lower and it doesnt throw the car off balance when you steer. The differentials (front and rear) are relatively much smaller than the MTX-3, which provides a less rotating mass and more acceleration. The same goes for the clutch bell. Stock MTX-3 pinions are 21/27 while stock gearing for MTX-4 is 17/23. The brake system also changed and now only uses one disk, instead of two plus the one in the middle. The rear shock tower provides a larger window of tuning due to all of the holes you can change the shock position to. The rear arms are 5.5mm longer which provide better rear traction.
