there is no vibration felt in anything, as far as it being in sync no not really. just a random crunching sound. if i let off or just eaze up on the acceleration it will stop. also if im up to say 35 mph and stomp on it its only slighty there
keep in mind its very hard to stay on the gas when its making such a horrendous noise so i have never played it out until it stopped so im not sure how long it would do it
