Fuchs style 17 inch CNC Rim

As I need to fit 17 inch rims to my 1977 930 to allow the use of 993 T calipers, and wanting to keep the Fuchs style rims, I got to thinking about the possibility of CNC machining rims as opposed to using cut out Fuchs centers to make up 2 or 3 piece rims.

Any thoughts/ experiences on this thought? I am sure many have thought of it in the past, so I am wondering why thee is nothing on offer?

I have access to a 4 axis machine and a good modeler (3D) as well as various qualities of billet-

If this concept does work, at least I can make the exact in-sets I need and be able to make replacements if I should damage one!

Jeff Alton makes 17" "Fuchs" that are forged. Search on here and you'll find him.

Mark, I trained as a CNC machinist also along with the 3D modeling using Mastercam.

If you have access to a 4 axis machine I say go for it. I don't know why nobody is making them. I would think with all of the extra 3 piece wheels out there many people could use them instead of buying completely new.

Let us know if you decide to make some.

I've machined centers and then bought the rim halves. It's certainly doable, but the rim halves probably run over $200 per wheel and the billet aluminum for the center is probably around $100 to $200 per wheel. You can buy a wheel for about $500, so there's not as much savings you'd think.

If you have access to free billet, then it's another story.

Zuffenhaus is now making/selling the 3-piece 17" Fuchs replicas that Jeff Alton originated. Not cheap, but sounds like exactly what you're looking for. Why futz around with development (in terms of time and money) when someone else has already done it? There's a reason it took Jeff, a guy who earns his living in the high performance wheel industry, a couple years to get the project rolling.

I have a pair of 11x17 3 pc. Fuchs for sale if your interested. The backspacing is 6.5, so you would need spacers.

Thanks for the input, as I am in Africa it will be better for me ( and others!) I think to be able to make a Custom Wheel locally in terms of insets/ offsets/ widths and to be able to test fit

Onc e the mapping is done, it is a relatively simple process to make dimensional changes to these parmeters ( or so my guy tells me)

I like the look of a non 3 piece rim, ie do not like to see bolts no matter how well painted they are, so a 2 piece or 1 piece rim is the way to go for me.

The cost factor is an issue, but if I factor in freight to Africa, duty etc, plus the risk I may have the incorrect dimensioned rims, it makes the lump a bit easier to swallow!

We will also be able to tweak the outers slightly to get a nice looking flow line

You can put the bolts on the inside so you can't see them. That's how my Kodiaks were made:




There's just so much scrap if you machine it from a single piece that it seems hard to justify. I guess you're far enough from a manufacturer though that it might be worth if for a few wheels.

10 " Fuchs

Are these rear wheels (shown above) 9" or 10" aftermarket fuchs?

I need a pair of 10" rears for my 74. I have thought about getting some 8" and have them widened to 10"

What tire size are those?

I can only find Kumos sized at 265/45/16 at the widest.

Will that work out fine?

Ideas?
