Just as a quick note on the metric wheels... Michelin was more responsible than ALFA. Peugeot and some others gave those a try too. Michelin thought it seemed silly to make 15" tires, when everything else had gone metric. Their plan, as I heard it, was that they would initiate metric, and Good Year and the rest would have to follow suit. Leaving the competition in the dust, and looking antiquated. The other tire companies would have to play catch-up in the development cycle and getting them into the pipeline. Turns out, it backfired on them. No one else bought into that system, and Michelin found themselves to be the only BetaMax in a VHS world.
You can still get new Michelin TRX metric tires, through Coker Tire in Chattanooga. They even say Michelin on them... identical to the 1985 tires in every way. Even the 25 year old technology in manufacturing them! As a street tire, I have no problem with them (stiction to wear ratio is actually pretty good). As they are now constructed by the same company that you would get new tires for your Ford Model 'A' from, the price seems to get even more expensive over time. Dang... and I found those metric Speedline 'phone dial' wheels the most gorgeous of all the options (stock and aftermarket).
I've had GTV6s with all 3 rim designs. Each has it's own beauty:
1981-'84 Campagnolos--- a bit heavier than the other two, but also more bullet-proof. Not as unique as the other two, thanks to a 4 year run. The other two were only around one year, each.
1985 Speedlines--- pure eye candy visually, but req metric tires (aka 'phone dials')
1986 Speedlines--- almost as pretty as the metric rims, Lightest of the 3. But a bit fragile in pot holes and curb scuffs. Prone to warping. (aka 'wine glasses')
You're likely going for an aftermarket rim... so the above may only provide historical insights. And not get you any closer to a Ronal, OZ, or such.
There were some ALFA rims on later models: 147, 156, and maybe 164s... that had some of that 'phone dial' styling. I might be interested in a set of those, if I knew that a 16" or 17" had proper diameter and offset clearances in a GTV6 wheel well. Anyone know the answer to that??
