ya when i reach speeds of around 70KM/H and then speeds over 100KM/H, while lightly pressing down on the gas, i feel a sort of vibration , not on my foot persay, but like from the car. Its like if u go over those little bumps on the highway that r supposed to slow u down.
does anyone know wat im talkin about? 89' PA by the way.
