Re: traction control issues
Not to be a big troll or anything, but you could learn how to drive the car. I never turned my traction control off and I slid aroud the corners just fine. Ask itsky, he rode with me all weekend last spring dragon.
Are you trying to "drift" the car or whip around the turn with a little back in wiggle? If you're trying to drift it you've picked the wrong car. BTW changing the diff will just put your car into limp mode.
