Hey guys, I am new to the Terminator model. Had an 01Cobra for some time. Is it normal for the car to shake/vibrate at above 100MPH. I had the car up to 145MPH last week and it was shaking during deceleration. Was not sure if it was driveline or tire out of balance. Chime in if you can. Normal or not normal. Is it supposed to be smooth as butter above 100? Below 100, no issues......Smooooooth.....
