The front wheel brake disc/hub connection is changed since the production of 1981 models. The flange and ring connection has been changed to a brake disc shell connection as on the 911/3.0 Itr. Turbo.
By designing the new brake discs with a shell the total distance (brake disc - hub) is 21 mm longer. Consequently the installation of 21 mm spacers is omitted. It is not permitted to additionally install spacers with the wheel hub.
Conversion to new brake discs/wheel hubs is only permitted on both sides simultaneously for 3.3 liters cars before 1981 models.
Removing grease caps is different due to the modified hubs. Old Version
