Other Information on this swap[edit]
This swap is known to work with the 87-89 turbo and non turbo wheels. 1986 Non turbo wheels rub the caliper slightly at the bottom face caused by the hub section of the wheel. At this time it is unknown if the 84-85 Turbo and non turbo and the 1986 turbo wheels will work without rubbing the new caliper.
