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

Every set of halfshafts is built on order according to customers specification

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

but then the factory designed kinematics wouldn't work as it supposed to

The result was more grip at the front and more precise steering
