ats cups 5.5x15 helpp!

I have just brought some ats cups that are the 5.5j ones. I have seen people saying they are rare and that the ones people have have come from the dutch rally cars as they are only 9 pound each.

I'm just wondering if anyone knows anymore about these wheels and if there was a lot made or if they were just for rally cars and I want to know what sort of price they sell for as I got them for 180 with tyres,, hope someone can give me some more info about these :) cheers
