once again, this spees specific vibration is 90% due to the unbalanced wheels. i had this problem for a while and i checked everzthing and it turned out to be unbalanced wheels. its a 5$ job for a wheel and u need to check only front 2 wheels. i think its worth trying to eliminate this cause b4 going to deep. dont repeat my mistake. i alreacy changed brake rotors, lower arms and a rim with a tire!
