I'm in the process of getting a 1972 safety certified (for registration in Ontario), and the inspecting mechanic has raised the issue of the lug-centric rear wheel design. While I'm pretty sure he's going to issue the certificate based on the fact that this is the way Porsche sold the vehicle in 1972, he has opined that changing a flat tire at the side of the road would be difficult or even impossible with this design...
I understand Porsche did change the hub/wheel at some point, so I guess I'm wondering if there's an option of "upgrading" from a 1972 rear hub to a later model year that would provide an easier way of centring a wheel on the hub? Or did the rear wheel design remain unchanged throughout the entire production period? Any insight here would be appreciated! |

Insert 3 bolts, replace screw-in stud with 4th bolt. google "14mm wheel stud pilot pin" , and feel free to share with the inspector. |

It's actually quite easy but most of us are trying the wrong way...... just lean the wheel against the hub and start any lug bolt that lines up... then rotate that one to the top and presto, all the others line right up... much more like dance than wrestling.... |
