i was on the interstate last night and noticed the car starting to sway back and forth while boosting in 4th gear( I have a 6 speed) Im a 4th gen though. Im guessing Im around 300-325 to the wheels. It was almost like I had two flat rear tires But I did not. I held the gas about 60% when I felt it but it was not rear bad but you could definly tell it. What can I do to fix this? has anyone eles had a problem like this other than torque steer!
