Hi. I am new to site. Used to have a 1966 mini cooper S. I am curious about a wheel I had for it. It is a black wheel, painted I think that was magnesium I believe, It was eight spokes and had a goodyear blue streak. Can anyone tell me anything about this? Was it an option, aftermarket etc. I assume it was for racing but I have seen nothing like it since thanks for any information. JW
