If you want to grab some measurements I would be curious about that. Circumferences will be the most accurate measurements for that stepped down portion and we can do some math from there. I don't know if this something I would jump at, especially as I don't have a lathe big enough, but I was curious at the possibility. If they're close and the material is there then you have the best of both worlds. However you run the risk of ruining a rim or weakening the rim where it counts.

I did some googling and the size of that rim is 365mm, or 14.37". It looks like it would have to get turned down to a 14" rim unless they measured from some weird diameter.
I'll make a note to myself to go take some measurements in the AM. I have some 15" wine glasses right next to the phone dials. So, I can give you both to work with.

Oh no... my cover is blown! Now the KGB, CIA, and al queida know where my kids go to school. Time for a new alias. The witness protection program is not going to like this very much :- )

I would do the analysis on that, maybe even do some finite element analysis for the lightened rim to make sure that it's structurally fine, but I would probably advise you ask a machine shop about that job. It's a very quick and not at all hard task to do, I could give you an engineering print to give them. The folks of the 'BB might appreciate the option of running the metric rims with ordinary tires.

I had abandoned that option for myself a while back. Once I had heard that it was not possible.

But I'm willing to pitch in the dimensions, to revisit this as a possibility. If my rough scaling show some promise, I could loan an extra rim to get more exact on. Details on the back side of the rim might make it, or break it, too?

Hi Xander,

I found a few moment to break out a couple of wheels to measure. I tried to be as accurate as possible, given my tools. Here are some numbers to play with:

A) Max OD on the face of the rim
B) The diameter that steps down inboard of the max OD, where the ID of the tire would sit
C) Circumference that describes 'B'
D) Diameter that defines the internal walls inside 'B'/'C' (there is a generous draft angle in the holes on the metrics, here [10-15 degrees, perhaps]. Not as much draft on the 'wine glasses').

Metric TRX rims:
A) 15.38"
B) 14.294"
C) 45.09"
D) 13.865"

Speedline 15" 'wine glasses':
A) 16.31"
B) 14.69"
C) 47.00"
D) 14.46"

When you compare the math on diameter vs circumference... I did not make that calculation. So, hopefully those come out close.

Remember, in geometry class, they taught you that Pi R square. Not true!...
Pi R round... Cake R square. :- )

Cheers,
Peter

Xander...

I tried to respond to your question via e-mail... but the edu address got returned, twice.

Do you have another address I could use?

Cheers,
Peter

16" AR wheels on GTV6

This is my '83 GTV6 which has had a full restoration and is expected to be "on the road" Mar '13.
3.0 + power steering from 75 (Milano) fitted.
Wheels are from AR 916 GTV model (not in USA), 16x61/2, 5 bolt 98mm pcd with 30.5mmm offset. hub dia had to be increased by 0.5mm. Lots of room for bigger brakes.
I think these AR wheels with large disk area look a lot better than "spokey" aftermarket types.

these are a style i am very keen on.

have a set similar made by speedline that were mounted to my 308 before i bought it.

would be interested in a similar wheel to ones pictured above.

anyone know the make and model?

Joe check out my thread "What wheels are these".
Nice car by the way, I've been watching that one for years, very glad to see it go to a great new owner!

thanks glen,

spend too much on correcting issues from loading in colorado onto the transport and was not expecting those costs.

but the goal over summer and into fall is to correct the very wrong things and then tackle the little things during the winter before it gets a respray.

then i need to find a terrific set of wheels to set it all off

It bummed me out hearing about the bad "transport" company. I know getting money for damage from auto transport drivers is pretty well not worth the effort and negative communication and energy,,,
That said, I seriously applaud you rolling with it and embracing that great car.
You need some bits, I'll be glad to help if I can.

yeah i didnt spend much time spinning my wheels with anyone.

what i will need is help figuring out the speedo on the car. i can drive very happily and easily with a rev counter. i spent so much time on track with my bike programmed to run the tack and shift lights only that is how i run my bike on the street. rev counter and feel for speed has served me well for nearly 10 years,,,,but a speedo might be a good idea at some point i suppose

ohhh and the passanger side signals do not work. both front and rear. no flasher sounds from under the dash. will begin to tackle that this week i think. hoping its a bad fuse,relay,flasher unit and not a bad steering stalk unit.

GTV6 Wheels

Thought I'd chime in...Charlie at Serpent Autosport sold me some rims. they look great, I'm very happy, and Charlie is as helpful as anyone I've met. give it a shot.
