more about Fuchs, Fuchs Options

[ME733]

You have asked about the fuchs which came on my 914 S....here goes...the O.E.M. spare rim is dated 8-72...and so are all the others.....and they are part#...914.361.011.00 .They look different in /on the backside than THE PHOTOGRAPH with notes you have shown......as a point of intrest the spare RIM and ALL the four on the ground are identical in every way...EXCEPT the four on the ground have a Painted BACKGROUND.....and after looking closely with a magnifing glass its obvious they are painted...and not quite dead flat black....they are Not anodized....the spare tire is an original tire ..DUNLOP 165 hr 15....looks like it and the rim have NEVER been used...the rim is clean and perfect (both sides and the tire has full tread....and is not dry rotted.(cracks showing in sidewalls)..However,.I would never consider using it obviously.

In my experience there were 3 front brake rotors used in production, with the mid version being a half step between the others. The first rotor (still available) is for the early cars with the early (single bleeder) calipers and struts. The last rotor (still available) is for the late cars with the late (dual bleeder) calipers and struts and is hub-centric. The mid rotor (not available soon after the late rotor came out) is for the late cars with the late (dual bleeder) calipers and struts and was not hub-centric; these appeared on late 1972 MY production with the introduction of the new struts and calipers, and were discontinued during the 1973 MY. It would be very rare to find one today. If I can find the part #'s then I'll edit this post.

Anodizing is essentially the creation of a hard oxide layer on aluminum, and this oxide is also known as ceramic. Cast aluminum parts are generally too porous for anodizing, hence the Pedrini and Mahle rims were painted. There are special primers used on the bare metal, and these are usually colored. The magnesium gasburner Mahle 5 bolt rims had a turquoise primer under the silver paint.

The alloy-wheel bolts (the long ones) are steel, with a copper plate layer, and a top cadmium plate layer. Often, when the cad layer is worn away, you will see a green/blue layer underneath that is the corroded copper layer.

I believe that both Pedrini and Fuchs came in non-hubcentric versions. Pedrini rims came out early before the change to the calipers and struts, so were for the first rotor version. Fuchs came later, and were initially used with the mid version rotor. After the hubcentric rotors came out all rims were available to match.
