When you think the tc4 is dead, it rises back up from its ashes... Driver patience in attaining knowledge is key here. Look at how long I've been posting here, and you'll understand the tenacity necessary to make the tc4 go faster in a world where everybody's bashing it... I receive little help when I go to race my tc4 in 17.5t blinky, and all the racers cringe when they see me pass them, eventhough I'm still not driving up to the car's ability yet... I recently watched DJ apolaro's video on swaybar tweak, and learned of another mistake I've been making all along... Give it time and effort, and don't get discouraged ever !!!
