i dont see why you would need a bucket for a street car. only reason i would run one is if i only put it on for an autox event. OR a car with a cage and a helmet. the stock seat belts are designed for you to fall to the center of the car in case a flip does occur. with a bucket seat you render your stock seatbelts useless, forcing you to use harnesses. since you have a harness you are unable to move as the roof caves in and snaps your neck.
