Speaking of replicas, I was pleased to find that my 15x7s are indeed real and not fakes, as I had secretly suspected all along.
Each are stamped like this (after scrubbing off a few years of road grime and brake dust)...
When I saw the little fox heads on all four wheels, along with the smooth finish on the back of the wheels and the 911.361.020 part number I danced a jig in my front yard.
