I havnt had this problam very long but my drivetrain has been shaking realy bad whenever i take off from a stop or revers...once im moveing faster then 5 mph it drives smooth, its really hard to get someone close under the car to look at it since the car has been lowerd..and to tell ya the truth this all started whenever i raced a mustang and my car started to wheelhop very bad..what could be the problam?
