BMW E9X or Lexus LS (UCF30) steering rack is needed to be used with this kit to replace the original electric power steering

We recommend tire diameter not bigger than 620mm (235/40 R17)

The knuckle has been designed to allow more suspension travel with the trending long stroke coilovers

The upgraded knuckle has been reinforced and has more room for bump steer adjustment
