I do know of at least one person that ended up with 10.87"caliper brackets that thought they were getting 11.75's based on the year/make/model of the donor car though, and we all know how honest everyone is on eBay .

I had the same concern about sizing. I e-mailed iRotors ahead of time for the specs, and they sent me the below, which was exactly what I received, except for the weight, which was off by +20 lbs.

FWIW,
my A-body 10.7" rotors weighed 22 lbs
the Cordoba 11.75" rotors weighed 27 lbs
