Now the big one. This is where Eric really let his imagination run wild. He was looking at all sorts of wheels of all sorts and it was up to me to tell him if it was or wasn't at all possible. He was willing to run a bolt-on adapter if we could make it work.
He looked at everything - old Cosmics on Triumphs, Maserati Merak wheels, Mahle "gas burners", you name it. It was quite entertaining.
The classic five-blade Fuchs? Unfortunately, no. You can't overlay a 5x130 pattern on a 4x100 and there were some problems with brake clearance on that big an adapter. Anything's possible, but this would have required custom hubs and brakes. Just in case anyone says "but I can get this adapter for my VW" - yes, you can. The hub bolts they use allow it. But a hub with studs won't.
He considered several steel wheel options, and we became conversant in the number of holes found in many aftermarket steel wheels. The more the better, and there's a set of Cobalt steel wheels that was very seriously considered. He also was fond of the steel wheels and hubcaps found on BMW 2002s, and even bought a set of 14" ones. Unfortunately, when they arrived, they were really 13". Tire availability took that size out of contention.
And again, the final answer was Porsche. Four-bolt Fuchs, to be exact. They're reasonably light, 15" so tire availability is good, and they had the look he wanted.
An adapter was needed to match the Porsche 4x130 bolt pattern. The adapters are 25mm thick, and this gives the wheels an effective offset of +17. That's a bit on the low side for a Miata, but not out of the question. As you can see, the adapter just barely fit into the stock brakes. It wouldn't have worked with 1990-93 brakes. We just contacted Adapt-it and told them the car and the wheels. They took care of the rest, quite quickly.
Here's the final result. The wheels have a satin finish on the recessed regions and are polished on the face, but the overcast light hides this. The final result is not to everyone's taste, but Eric loves it.
You can see the cut rear bumper in this shot.
The extra offset of the wheels effectively softened the V-Maxx suspension, which gave the car a really nice fluid ride on bad roads. We did find a bit of rubbing when running two-up on my "Targa Simulation Road", but a bit of rolling took care of that. Yes, the car is on jack stands.
