Small vibration under HARD acceleration
Can feel a little vibration under really hard acceleration (floor gas at 1st/2nd gear. vibration happens around 3k rpm or more)
otherwise the car is firm.
Recently replaced guibo.
But not sure if the vibration is because of that, or because of chopped and unbalanced tire.
(autocrossed last weekend and I believe the tires had a hard day)
Is it possible that sliding in autocross could cause the tire unbalanced and have noticeable vibration?
no vibration if going smoothly.
