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.

the anodizing is a heat tempering process

Anodizing in an electrical process involving cathode/anode interactions in a chemical bath. Heat isn't a significant part of the process. Anodizing makes the surface harder and impervious to oxidation. After anodizing, but before sealing, a dye can be sprayed, dipped, or brushed onto the part to color it.

So McMark - on those 2L alloys - did they color the background to that matte or satin silver finish, then seal them???? (IMG:style_emoticons/default/confused24.gif)

If so, what is the correct dye & finish on that background area??? (IMG:style_emoticons/default/confused24.gif)

...as opposed to the semi-polished "petals" or "windmill blades" & rims or lips below:

The 'color' difference in this case is a factor of pre-anodizing surface finish. Anodizing is not thick and so will 'show through' any finish on the base metal. Anodizing does reduce any polish slightly, and that's why aluminum trim will never be as reflective as chrome trim. The difficulty in refinishing wheels like this is how to reproduce a non-directional satin finish. Bead blasting is too coarse, sanding leave directional scratches, but perhaps something like soda blasting would work (or some other media, maybe plastic?). Al Reed certainly has this down. He did a set of RS-look five lugs for me that were perfect (RS-look is just like ours, satin background with polished spokes/paddles).

Yeah - Al has it down, he had loads of finished 5-spoke/lug Fuchs with various finishes & was explaining to me that he has some sort of a fine bead blast or something to get the 2L 4-lug background finish - but anodizes first, because he found if done after it turns dark.

btw - side question - when you do those 2056 Raby kits on the 2L, does that retain the D-jet & at what HP & Torque??? (IMG:style_emoticons/default/confused24.gif)

A 2056 Raby kit is about 115hp with the Djet...makes the 914 a different car.
