Great looking wheel. Makes me sad. Did I mention that yet?
I wonder if the 5 x 130 bolt pattern in a 16 inch size could be considered as an option, just saying, that would open up an even greater market. I have 16x6 and 16x7inch I don't know the offset off hand but if you have 911 sc front brakes it would be nice and Stan is right the 16 inch rubber still has some choice. A lot of builders who are using more expensive wheels might be chasing you down to get them. 
Um I'm new here
just not sure if this could be considered part of the topic
I have a set of these:

I agree, 17's don't look right and have no rubber unless your doing a "Donk"
Donk ?
There are low profile tires that can give you 17 or even 18 inch wheels.
I would think that you need full 911 suspension to really handle this with sway bars and maybe even power rack and pinion. It would be pretty much a full on go kart.
That is if you like or can endure the harsher ride. You might need a kidney belt to survive a cross country trip on rough pavement roads.
On the other hand for a street cruiser, light to light, it would be a flat out Rebel machine especially with a Flat 6 with 300hp.
While I can appreciate that kind of rocket ship building, I am more of a classic car nut so the rocketship, is not my cup of tea, you see I don't like to wear a parachute it does not fit my seat properly.
With a 3.75" backspacing (12mm offset) these may not fit in the back of many speedsters, when mounted with a 185/65 tire.

If you measure out the back space on your wheels now, you will find a 3.75 back space. All the aftermarket wheels have a 3.75 back space. Here is the thing, you can always space them out if you wanted, but you can't space them in.
The only issue I have ran into with the 3.75 is with IRS and the adjustable spring plate. The adjuster rubs on the tire. Easy cure, add a wheel spacer to get it out. Don't need much. If we make a rim with a 4" back space, a lot of Speedster will have issues with tire rub inside the finder (Can't space in).
We have a lot of R&D in the wheels, and as much as we would like to make a one wheel fit all perfectly, it is just not possible. Bug, Bus, Speedster, Porsche, Spyder, dropped spindles, IRS, Swing axle, short swing axle, long swing axle, Just goes on and on. We know that this wheel will fit the majority with no issues.
Trust us, we have done our homework.
For some reason I LOVE tires and wheels, so I did some research:
Stock Beetle tire diameter for a 165/80-15 tire is 25.39" so that's the approximate diameter we're aiming for.
Here's some diameters in other tire sizes:
185/65-15 24.47"
195/60-15 24.21"
195/50-16 23.68"
195/60-16 25.21"
195/55-16 24.44"
It's getting near impossible to find a performance tire in a 15" 60 or 65 series tire, so let's look at 16" sizes:
Seems there is very little, performance wise, tire selection in a 195/60-16 tire. The only one I could find was a Kumho ECSTA PA31 all seasons performance tire. Since it's an all seasons tire I suspect it's comparable to the 15" all season performance tires offered in a 185/65-15 size, which do nothing to improve our cars' handling.
Seems we can still buy some excellent handling tires in the 195/55-16 size. The tire diameter is a bit smaller than we'd like, but still not that far off
Below I've listed three. The RE-71Rs* are as good as you can get-would be a great track tire and absolutely awesome on the street.
*Bridgestone Potenza RE-71R
Bridgestone Potenza RE760 Sport
Yokohama Advan Sport ZPS
New wide-5 aluminum wheels with RE-71R tires would be an awesome combo. 
Appears the Western/Gurney wheels are knock-off of the McAfee racing wheels???
"I found some interesting notes about these wheels. According to jackmcafee.com, these wheels are clones of the Porsche "McAfee wheel". From what I have read, these wheels were sold by more than one manufacturer and the differences primarily came down to the center caps. This one appears to be the style with the bolt-on center caps, whereas my wheels have caps that slip on from the back.There are two different styles of slip-ins (like mine) and the style that uses these bolt-on caps."

I would be too embarrassed to drive or even ride in this! Even if it was the neighborhood where it's regarded as cool.
I'm assuming 5 1/2" wide wheels. If you have a 4" back space like an empi 8 spoke and it hits the suspension, you can space it out. If you have a 3 3/4 back space like a chrome wheel and it hits the body you can't space it in

I have always wondered how accurate this calculator is https://www.tacomaworld.com/tirecalc
One thing I found out is that the 165 80 15 is shorter than the metric size of 165r 15. And to top it off all tire manufactures size there tires a little different. i.e. not all 195 65 15 are the same size.
16" do have better performance tire options, but not everyone wants the tire profile of a 16" wheel. Like I said, it is hard to make one wheel fit all and the cost to make 6 different rim sizes and to hold on to the inventory is huge. We are doing our best to provide a viable option for a cost effective wheel to fill a gap in the wheel market. Plus we are tired of trying to source a good wheel. Most of the aftermarket overseas wheels are eggs, wobbly and not eccentric.
I got a set of cheep round imported tire because I needed some in a rush and was blown away with the grip, performance, and millage wear. So much that I am getting another set for my little canyon carver. The bad thing about them was once they got past the wear limit mark, they wore very uneven. No bid deal, they were wore out and needed new ones anyways. Won't post the brand, but if you want to know PM me.

I have found the same thing on my CMC body with IRS. In order for a 5 1/2" wide wheel to fit I need a 4 - 4 1/4" backspacing. IRS. The suspension is not as much the problem as the body.
3 3/4" backspacing works for 4 1/2" wide wheels, but 4 1/4" is more appropriate for the 5 1/2" wide wheels.
Greg;
So you have the Western Gurney / Mcafee wheels? Cool. For some reason I thought you had Fuchs 914 2.0 Ltr. wheels, like I have. My centers caps have to be hammered in with rubber mallet and a little black chaulk. The previous owner(s) had ground down portions of the male part. And somewhere in time rivets had been used??? I still like them, though. I have seen far worse on a CMC.

Art - I have 2L Fuchs on my CMC. The Western wheels were on a '72 914 I bought new way back and replaced the plain jane steel wheels. On the 2L liter wheels I have deeper billet caps that use a small hex screw to secure them --- maybe its that hex screw that looks like a rivet. How is clearance on yours in the back driver's side?
Greg;
My back drivers side is very tight, 3/16". BUT I have not done the CMC surgery. Dr. Clock and Gordon and perhaps you, gave me clear instructions. But I still haven't completed.
Yes and my billet caps are quite deep. So probably what I saw was set hex screws.
