I would disagree with this statement. Adding a Mismatched or Larger diameter rear bar may induce dangerous oversteer. Dialing in some Understeer is usually favored by car manufactorers because the car is still controllable and handling is predictable (i.e. limit product liability)for the majority of drivers. That being said, since the existing front bar is the same diameter for all years of PT's, adding the stock rear bar would make it a properly matched set.
