16x7 was a
standard size for the Pro race 1.2s, and was as readily available as any of their other stock sizes.
Ron (Whoosh Motorsports) was even selling a used set with winter tires a while back.
Many on here bought these in that size when they were still available, so maybe someone selling them will respond on here.
WAY WAY back when Chalon (Perfect Circle Autosports) was the US distributor, he was trying to get them to group buy/special build us a 16x
8 version, but that never happened
.
Sadly, except for the 15x8s through Phil's Tire Service (and the 15x8 KE Motorsport Pro 'copies' of them from the same), the Pro Race 1.2s are gone forever in any other size to fit our rides.
