Well I did a google search of the sparco rims and I found one pic that looked like the ones you have pictured here. But my work internet is restricted and wouldn't let me open the pic up. Just type in sparco wheels and scroll down a bit till you see it.
You guys might be right and wrong, cuz I had the real ones for over 25 to 30 years
If you take a closer look the rota reps, the pattern touch the lip, the reals ones are RS betas they dont touch the lip
