I can't say I've noticed any vibration, but my 2019 RS definitely torque steers more than any other car I've owned. I could imagine a situation where an LT model with lighter wheels and probably less aggressive tires could suffer even more from it.
Doesn't bother me personally. Even with a relatively lively engine applying its torque to the front wheels and the leverage advantage of 9 gears, I figure GM could have engineered it out. But I am content with where they spent the money to develop this car.
