Is anyone running a True-trac posi in a car with a 12bolt. I would like a review- pros/cons? Usage will be autocross and street with some drag racing. Thanks, SS

It will be the best differential for autocross. It will not upset the chassis or tires as much as a clutch type posi. I have heard that sometimes they will allow one wheel to spin when doing a burnout, but a touch of the brake pedal will get the other wheel spinning.

thank you BGH, SS.
