If you're not "one legging it" and doing one wheel burnouts then the factory traction control is doing it's job. A really "tight" posi unit can make a car really oversteer badly on wet roads. I put a Auburn posi-pro unit onto my '97 RWD Cougar and two weeks later backed her into a guardrail on a curving wet entrance ramp when I kicked 'er down trying to accelerate around a curve. $ 1,700 poorer and much wiser ! A Crossfire is a stubby 95 inch wheelbase RWD vehicle without TC/ESP It would want to swap ends on you every time it rained !
