I just got a used Challenge car that has been raced for a few years. Everything looks great. So took it to a track time event at PBIR and it seems like there is something going on with the rear end. When you do a normal fast shift up, the rear end takes a quick kick to the right making the car take a quick jerk to the left. If you do a slow, grand ma easy soft off throttle shift almost no kick. A hard accelerate on the shift the rear end takes a quick kick to the left, making the car take a kick to the right. It is acting like worn out bushings in the rear 3 link drag bars letting the rear end torque steer the car. I checked the rear end as well as I could at the track, but what little I could see the bushings looked fine. Any thoughts before I start tearing the 3 link apart?
