I have a 76 914. How can I tell if a Fuchs, or a Mahle 4 bolt wheel is 'hub centric'?

I wan to say they should be labeled on the inside of the wheel.

I opened a post in our forums. A Pelican community member may be able to answer your question.

All of the Mahle wheels should be hub-centric.

Almost all of the Fuchs wheels should also be hub-centric. There were a very very few Fuchs wheels made early on that were lug-centric, but those are quite rare. The back side of those wheels looks fairly different than that of the regular hub-centric ones. I used to have a photo showing the back of one that I found at a swap meet, but I can't find it now. I don't think there was a part number change for that, but I could be wrong.


Oh--for completeness' sake: Most Pedrini wheels are lug-centric. There was a version made that was hub-centric for the 1973 model year; the part number on those ends in "01", while the part number for the regular lug-centric Pedrinis ends in "00". Those numbers are cast into the back side of the wheel.

Here's a pic of the back of a regular Fuchs four-lug wheel, the one that is hub-centric, courtesy of the folks at 914world:




The lug-centric Fuchs look different; the recesses in the back (where the part numbers, etc., are seen) are a different shape and the cut for the hub-centering ring is not present.

The wheels can be hub centric, but is the hub on the car? With your 76 the answer is yes. On earlier 914s the hub part of the disc is smooth/flush with no raised circular part for the wheel to mate with. On these cars the bolts centered the wheels which was not optimal which is why Porsche changed to hub centric in 72 or 73 (don't recall exactly). I know this because I had issues with swapping out parts on my racer in the early days and having wheel fitment issues.
